A tyrosine-rich domain within homeodomain transcription factor Nkx2-5 is an essential element in the early cardiac transcriptional regulatory machinery. (1/33)

Homeodomain factor Nkx2-5 is a central component of the transcription factor network that guides cardiac development; in humans, mutations in NKX2.5 lead to congenital heart disease (CHD). We have genetically defined a novel conserved tyrosine-rich domain (YRD) within Nkx2-5 that has co-evolved with its homeodomain. Mutation of the YRD did not affect DNA binding and only slightly diminished transcriptional activity of Nkx2-5 in a context-specific manner in vitro. However, the YRD was absolutely essential for the function of Nkx2-5 in cardiogenesis during ES cell differentiation and in the developing embryo. Furthermore, heterozygous mutation of all nine tyrosines to alanine created an allele with a strong dominant-negative-like activity in vivo: ES cell<-->embryo chimaeras bearing the heterozygous mutation died before term with cardiac malformations similar to the more severe anomalies seen in NKX2.5 mutant families. These studies suggest a functional interdependence between the NK2 class homeodomain and YRD in cardiac development and evolution, and establish a new model for analysis of Nkx2-5 function in CHD.  (+info)

On the depth and scale of metabolic rate variation: scaling of oxygen consumption rates and enzymatic activity in the Class Cephalopoda (Mollusca). (2/33)

Recent ecological theory depends, for predictive power, on the apparent similarity of metabolic rates within broad taxonomic or functional groups of organisms (e.g. invertebrates or ectotherms). Such metabolic commonality is challenged here, as I demonstrate more than 200-fold variation in metabolic rates independent of body mass and temperature in a single class of animals, the Cephalopoda, over seven orders of magnitude size range. I further demonstrate wide variation in the slopes of metabolic scaling curves. The observed variation in metabolism reflects differential selection among species for locomotory capacity rather than mass or temperature constraints. Such selection is highest among epipelagic squids (Lolignidae and Ommastrephidae) that, as adults, have temperature-corrected metabolic rates higher than mammals of similar size.  (+info)

A model biological neural network: the cephalopod vestibular system. (3/33)

Artificial neural networks (ANNs) have become increasingly sophisticated and are widely used for the extraction of patterns or meaning from complicated or imprecise datasets. At the same time, our knowledge of the biological systems that inspired these ANNs has also progressed and a range of model systems are emerging where there is detailed information not only on the architecture and components of the system but also on their ontogeny, plasticity and the adaptive characteristics of their interconnections. We describe here a biological neural network contained in the cephalopod statocysts; the statocysts are analogous to the vertebrae vestibular system and provide the animal with sensory information on its orientation and movements in space. The statocyst network comprises only a small number of cells, made up of just three classes of neurons but, in combination with the large efferent innervation from the brain, forms an 'active' sense organs that uses feedback and feed-forward mechanisms to alter and dynamically modulate the activity within cells and how the various components are interconnected. The neurons are fully accessible to physiological investigation and the system provides an excellent model for describing the mechanisms underlying the operation of a sophisticated neural network.  (+info)

Ethics and invertebrates: a cephalopod perspective. (4/33)

This paper first explores 3 philosophical bases for attitudes to invertebrates, Contractarian/Kantian, Utilitarian, and Rights-based, and what they lead us to conclude about how we use and care for these animals. We next discuss the problems of evaluating pain and suffering in invertebrates, pointing out that physiological responses to stress are widely similar across the animal kingdom and that most animals show behavioral responses to potentially painful stimuli. Since cephalopods are often used as a test group for consideration of pain, distress and proper conditions for captivity and handling, we evaluate their behavioral and cognitive capacities. Given these capacities, we then discuss practical issues: minimization of their pain and suffering during harvesting for food; ensuring that captive cephalopods are properly cared for, stimulated and allowed to live as full a life as possible; and, lastly, working for their conservation.  (+info)

DIGITAL.CSIC: Are pelagic cephalopods in the Mediterranean as abundant as suggests the stomach contents of their predators?DIGITAL.CSIC: Are pelagic cephalopods in the Mediterranean as abundant as suggests the stomach contents of their predators?
According to most specialists, the dearth of information on oceanic cephalopods reflects the inability of present day sampling equipments to catch them, since stomach content analyses of their predators suggest that they are very abundant along the water column. Stomach analyses, however, have an important inherent problem that should be taken into account when addressing this hypothesis. Cephalopod flesh digests more quickly than fish flesh and, in most cases, the identification of cephalopod remains is done from beaks, which are difficult to digest and may accumulate for long times in the stomachs. Such beak accumulations obviously bring forth an overestimation of the importance of cephalopods in the predators diet. With the expectation of determining if pelagic cephalopod abundances in the Mediterranean are in agreement with inferences from teutophagous predators diet, we analysed the structure and dynamics of cephalopod assemblages at different bathymetric strata from the surface to bottom ...

Population Genomics of Three Deep-sea Cephalopod Species Reveals Conne by L. E. Timm, H. D. Bracken-Grissom et al.Population Genomics of Three Deep-sea Cephalopod Species Reveals Conne by L. E. Timm, H. D. Bracken-Grissom et al.
Despite the ecological importance of deep-sea cephalopods, little is known about their genetic diversity or population dynamics. The cephalopod species Cranchia scabra, Pyroteuthis margaritifera, and Vampyroteuthis infernalis are commonly collected in midwater samples from both the Gulf of Mexico and northwestern Atlantic Ocean but, despite their common appearance in trawls and important roles in marine food webs, no genetic studies of population connectivity exist for these species. Here, Sanger sequencing of three conserved genetic loci and ddRADseq techniques were used to examine population genetic dynamics in these deep-sea species. Genetic diversity is lowest in C. scabra, which appears to be in a population growth stage, and highest in V. infernalis. Population structure was unique to V. infernalis but does not appear to be the result of ocean-basin vicariance, thus possible alternative explanations are explored, specifically environmental variation in dissolved oxygen. The genetic connectivity

Cephalopod genomics: A plan of strategies and organizationCephalopod genomics: A plan of strategies and organization
Within the Mollusca, cephalopods diverged from a monoplacophoran-like ancestor over 500 million years ago, later branching into the extant clades Nautiloidea (Nautilus and Allonautilus) and Coleoidea (squid, cuttlefish and octopus) [2,42-44]. The CephSeq Consortium has come together with the intention of using strategic genomic and transcriptomic sequencing of key cephalopod species to address previously unanswerable questions about this group. Taking into account the challenges of cephalopod genome sequencing, as well as the necessity to address nodal taxa, we have identified a set of species on which to focus our initial efforts. Selected species have been chosen based on the curiosity of their biological features as well as the possible advantages of their practical use. These species also cover ecologically diverse life histories, representing benthic, nectobenthic and nectonic animals.. Cephalopods are animals with advanced cognitive skills and a complex repertoire of behavioral abilities ...

what mollusks belong to class cephalopodawhat mollusks belong to class cephalopoda
This quiz is incomplete! Their shells are chambered and may be straight or spiral. Despite their name, cuttlefish are not fish but mollusks. Answer. This class includes the extinct ammonites and nautiloids. The Cephalopoda receive their name from having organs of prehension and locomotion attached to the head, an arrangement toward which a gradual approach may be traced in the highest gasteropod mollusks. They display vivid coloration, typically seen in squids and octopi, which is used for camouflage. The Cephalopoda are named such because they have a prominent head that bears long flexible feet. These are ancient species that are found in all of the worlds oceans, and are thought to have originated about 500 million years ago. The octopus, squid, cuttlefish, and chambered nautilus are familiar representatives. To this class belong the Nautili, Squids, Cuttle-fish, etc. … Question 6 5 out of 5 points The classes Gastropoda, Bivalvia, and Cephalopoda belong to the phylum Mollusca. The ...

As a squid biologist, I have always been a huge fan of living cephalopods, but their shelled ancestors never piqued my interest before I picked up Danna Staafs Squid Empire. Thanks, in part, to her unbridled enthusiasm, by the end of the book, I found myself actively rooting for animals that I had previously only thought about as fossils.. Early cephalopods used horn-shaped chambered shells to control their buoyancy, allowing them to bob and float above the seafloor. The resulting mobility allowed them to evade predators and capture prey. With an abundant amount of food available and a lack of competition, cephalopods flourished, growing to enormous sizes. (Fossils as long as 3.5 meters dating from the Ordovician have been discovered in Iowa.). Cephalopod evolution is a fantastic subject for lovers of drama: The moment the protagonist appears to be done for, a narrow escape ensues. When fishes developed jaws, cephalopods countered with beaks. When fishes became faster swimmers, cephalopods ...

A two day workshop on Southern Ocean cephalopods was held in Hobart, Tasmania, Australia prior to the triennial 2006 Cephalopod International Advisory Council (CIAC) symposium. The workshop provided a second international forum to present the current state of research and new directions since the last Southern Ocean cephalopod meeting held in 1993. A major focus of the workshop was trophic ecology and the use of a variety of tools that can be applied in Southern Ocean trophic studies for both cephalopod and predator researchers. New tools that are being used as trophic indicators and tracers in food chain pathways include stable isotope, heavy metal and fatty acid signature analysis. Progress is also being made on understanding squid population dynamics in relation to other key components of the ecosystem by incorporating squid data in ecosystem models. Genetic barcoding is now of great value to fish taxonomy as well as other groups and it is expected that a cephalopod barcoding initiative will ...

Talk:Cephalopod eye. The eye of a cephalopod is strikingly large for the size of the animal, and in the case of the giant squid represents the largest eye in the animal world, nearly the size of a dinner plate. Unlike the vertebrate camera eye, the cephalopods form as invaginations of the body surface (rather than outgrowths of the brain), and consequently they lack a cornea.

An exceptionally well-preserved fauna from a new exposure in the Peterborough Member (Oxford Clay Formation) of southern England, equivalent to the famous and now inaccessible Lagerstatte at Christian Malford, Wiltshire, is described. It comes from a single bed and includes coleoid cephalopods with phosphatized soft tissues, and fully articulated fish. The level is unusual in that it lacks permanent benthos and is dominated by rain-out from the upper water column. It was deposited on a sea floor that experienced prolonged periods of anoxia and which was overlain by a water column that was at least intermittently stratified. It is postulated that the coleoids formed large shoals that were killed en masse, together with other elements of the associated fauna, in one or more catastrophic mass mortality events that affected a significant area of the Peterborough Member sea. During the event(s), many of the coleoids preyed upon moribund fish and other coleoids, sometimes of the same species, before ...

Cephalopod - WikipediaCephalopod - Wikipedia
The traditional view of cephalopod evolution holds that they evolved in the Late Cambrian from a monoplacophoran-like ancestor[88] with a curved, tapering shell,[89] which was closely related to the gastropods (snails).[90] The similarity of the early shelled cephalopod Plectronoceras to some gastropods was used in support of this view. The development of a siphuncle would have allowed the shells of these early forms to become gas-filled (thus buoyant) in order to support them and keep the shells upright while the animal crawled along the floor, and separated the true cephalopods from putative ancestors such as Knightoconus, which lacked a siphuncle.[90] Neutral or positive buoyancy (i.e. the ability to float) would have come later, followed by swimming in the Plectronocerida and eventually jet propulsion in more derived cephalopods.[91]. However, some morphological evidence is difficult to reconcile with this view, and the redescription of Nectocaris pteryx, which did not have a shell and ...

Pain in cephalopods - WikipediaPain in cephalopods - Wikipedia
Examples of cephalopds Pain in cephalopods is a contentious issue. Pain is a complex mental state, with a distinct perceptual quality but also associated with suffering, which is an emotional state. Because of this complexity, the presence of pain in non-human animals, or another human for that matter, cannot be determined unambiguously using observational methods, but the conclusion that animals experience pain is often inferred on the basis of likely presence of phenomenal consciousness which is deduced from comparative brain physiology as well as physical and behavioural reactions. Cephalopods are complex invertebrates, often considered to be more advanced than other invertebrates. They fulfill several criteria proposed as indicating that non-human animals may be capable of perceiving pain. These fulfilled criteria include having a suitable nervous system and sensory receptors, opioid receptors, reduced responses to noxious stimuli when given analgesics and local anaesthetics used for ...

The Dragons Tales: Cretaceous Ammonites had a Sessile (!) Phase as JuvenilesThe Dragons Tales: Cretaceous Ammonites had a Sessile (!) Phase as Juveniles
Here we present evidence for a semi-sessile early juvenile stage of ammonites. Our hypothesis is based on fossil evidence in early diagenetic limestone concretions discovered in platy limestone deposits of Cenomanian age in the northern state of Coahuila, Mexico. In these locations densely packed post-embryonic shell assemblages were attached to fossilized algal or bacterial mats and preserved in sediments deposited under permanently anoxic bottom conditions. Tiny ammonites, as well as gastropods and byssate pectinid bivalves are abundant and restricted to these mats. They do not occur elsewhere in the sediment. The ammonite hatchlings were apparently unable to escape from mats sinking to the hostile sea floor and must thus have been semi-sessile, similar to the associated gastropods and bivalves ...

Tarrantites, a new heteromorph ammonite genus from the Albian of Texas and PakistanTarrantites, a new heteromorph ammonite genus from the Albian of Texas and Pakistan
ABSTRACT. A new heteromorph ammonite genus, Tarrantites, is proposed for Hamites adkinsi Scott, 1928. The description of the new genus is based mainly on a near-complete specimen from the Middle Albian part of the Goodland Limestone of Tarrant County, Texas, the holotype, and on an abraded mould on a pebble from the bed of a stream in Hill County, Texas. In addition, we record the presence of the genus in the Albian of Pakistan. Tarrantites shows a remarkable resemblance to the labeceratine genera Labeceras Spath, 1925 and Myloceras Spath, 1925: in coiling and size to the former, and in ornamentation to the latter, but is excluded from the subfamily Labeceratinae Spath, 1925, because it has a distinct bifid adventive (A) lobe. This latter feature, and the ornamentation, rather suggest affinities of Tarrantites with the family Anisoceratidae Hyatt, 1900..

Plectronoceras in an excellent place to start, even for the whole shabang, being the oldest known cephalopod, known from as early as the Franconian, lower Yenchou, of China. I added the Ellesmerocerida which are the root stock of all post Cambrian cephalopods. The Endocerida and Actinocerida are shown slightly differently to allow for the added Orthocerida. All three are independently derived from the Ellesmerocerida. The Orthocerida provides a place for the Bactrida to attach. Stemming from the Bactida are three independent groups, the Ammonidea, Aulacocerida (Belemnoidea) , and Coleoidea. The line of direct decent from the Ellesmerocerida continues to the Nautilida, which along with the Coleoidea contains the most recent cephalopods ...

Sentience, welfare and Brexit | Veterinary PracticeSentience, welfare and Brexit | Veterinary Practice
There are currently some interesting discrepancies between the AWA and the A(SP)A. The AWA applies only to (non-human) vertebrates. In contrast, the A(SP)A, as it was amended in 2012 to bring it into line with European legislation, applies to (non-human) vertebrates, and to any living cephalopod not in its embryonic form (cephalopods are invertebrates). Furthermore, whereas the AWA does not apply to animals in their foetal or embryonic form, the A(SP)A does apply to mammals, birds or reptiles in the last third of gestation or incubation, and to other foetal, larval or embryonic forms once they become capable of independent feeding. The sentience-based protections given by the A(SP)A are currently more wide-reaching than those provided by the AWA. The provision already exists in section 1 (3, 4) of the AWA for the national authority to widen the scope of the animals being protected if it is satisfied, on the basis of scientific evidence, that animals of the kind concerned are capable of ...

It is widely accepted that the effects of global sea-level changes at the transition from the Devonian to the Carboniferous are recorded in deposits on the shelf of northern Gondwana. These latest Devonian strata had been thought to be poor in fossils due to the Hangenberg mass extinction. In the Mader (eastern Anti-Atlas), however, the Hangenberg Black Shale claystones (latest Famennian) are rich in exceptionally preserved fossils displaying the remains of non-mineralized structures. The diversity in animal species of these strata is, however, low. Remarkably, the organic-rich claystones have yielded abundant remains of Ammonoidea preserved with their jaws, both in situ and isolated. This is important because previously, the jaws of only one of the main Devonian ammonoid clades had been found (Frasnian Gephuroceratina). Here, we describe four types of jaws of which two could be assigned confidently to the Order Clymeniida and to the Suborder Tornoceratina. These findings imply that chitinous ...

Ammonoidea - WikipediaAmmonoidea - Wikipedia
Some ammonites have been found in association with a single horny plate or a pair of calcitic plates. In the past, these plates were assumed to serve in closing the opening of the shell in much the same way as an operculum, but more recently, they are postulated to have been, instead, a jaw apparatus.[6][7][8][9]. The plates are collectively termed the aptychus or aptychi in the case of a pair of plates, and anaptychus in the case of a single plate. The paired aptychi were symmetric to one another and equal in size and appearance. Anaptychi are relatively rare as fossils. They are found representing ammonites from the Devonian period through those of the Cretaceous period. Calcified aptychi only occur in ammonites from the Mesozoic era. They are almost always found detached from the shell, and are only very rarely preserved in place. Still, sufficient numbers have been found closing the apertures of fossil ammonite shells as to leave no doubt as to their identity as part of the anatomy of an ...

The ability to regenerate whole-body structures has been studied for many decades and is of particular interest for stem cell research due to its therapeutic potential. Several vertebrate and invertebrate species have been used as model systems to study pathways involved in regeneration in the past. Among invertebrates, cephalopods are considered as highly evolved organisms, which exhibit elaborate behavioral characteristics when compared to other mollusks including active predation, extraordinary manipulation, and learning abilities. These are enabled by a complex nervous system and a number of adaptations of their body plan, which were acquired over evolutionary time. Some of these novel features show similarities to structures present in vertebrates and seem to have evolved through a convergent evolutionary process. Octopus vulgaris (the common octopus) is a representative of modern cephalopods and is characterized by a sophisticated motor and sensory system as well as highly developed cognitive

ABSTRACT: Coleoid cephalopods (squid, cuttlefish, and octopus) have the largest and most complex brains of all invertebrates and show behavioral abilities similar to those of vertebrates. Among the coleoids, the oval squid Sepioteuthis lessoniana forms well-structured schools that are indicative of sociality. These behaviors are reflected in aspects of the well-developed brain. In this study, we focused on the role of the cephalopod brain in complex behavior. In order to reveal the network of γ-aminobutyric acid (GABA) in coleoids, we examined the immunohistochemical localization of glutamic acid decarboxylase (GAD), which is the synthetic enzyme of GABA, in the brain of young S. lessoniana. We found that GABAergic neurons and their axons were distributed throughout the brain. GABA neurons were abundantly localized in the inferior frontal lobe, which is involved in controlling arm motions, and in the subesophageal masses, which are lower and intermediate centers of action. GABAergic fibers were ...

Cephalopods possess the most complex centralized nervous system among molluscs and the molecular determinants of its development have only begun to be explored. To better understand how evolved their brain and body axes, we studied Sepia officinalis embryos and investigated the expression patterns of neural regionalization genes involved in the mediolateral patterning of the neuroectoderm in model species. SoxB1 expression reveals that the embryonic neuroectoderm is made of several distinct territories that constitute a large part of the animal pole disc. Concentric nkx2.1, pax6/gsx, and pax3/7/msx/pax2/5/8 positive domains subdivide this neuroectoderm. Looking from dorsal to ventral sides, the sequence of these expressions is reminiscent of the mediolateral subdivision in model species, which provides good evidence for mediolateral patterning conservation in cephalopods. A specific feature of cephalopod development, however, includes an unconventional orientation to this mediolateral ...

Cephalopod gnashersCephalopod gnashers
Cephalopods can inflict a nasty bite. On their underside, at the conjunction of their arms, they have a structure called the beak which does look rather like a birds beak, and which can close with enough force to crush shellfish. Many also dribble toxins into the wound that can cause pain, tissue necrosis, and paralysis. They arent the best animals to play with.. If you think about it, though, cephalopods dont have a rigid internal skeleton. How do they get the leverage to move a pair of sharp-edged beaks relative to one another, and what the heck are they doing with a hard beak anyway? Theres a whole paper on the anatomy of just the buccal mass, the complex of beak, muscle, connective tissue, and ganglia that powers the cephalopod bite.. The beak itself is made up of a combination of chitin (a carbohydrate, the same stuff that makes up insect exoskeletons) and proteins. The buccal mass is a roughly spherical lump of tissues with a fair amount of motility and independence-the beak can be ...

ADW: Octopus vulgaris: INFORMATIONADW: Octopus vulgaris: INFORMATION
Octopuses can learn. They can make discriminations based on visual, tactile, and chemical cues. Octopus vulgaris keeps its home hidden. The females find a hole, a crevice or sheltered place ad they often protect their homes with shells, stones, and other solid objects they gather.. Members of this species are perfectly adapted to live in very different habitats. Their capacity to conceal themselves on any substrate by varying colour, skin, texture, and posture is challenged by few other cephalopod species. In the Catalonian Sea, more particularly in the area of Banyuls and Port Vendres, Octopus vulgaris seems to undergo seasonal migrations, mainly of vertical orientation. In the early spring, large animals move inshore for spawning. The females tend to disappear during the summer; they lay eggs, brood, and die. From late summer onwards, the largest size class consists mainly of males. They leave the coastal waters in autumn or early summer; at this time the males are mature, and the females at ...

Cephalopoda - Palaeos.orgCephalopoda - Palaeos.org
The cephalopods first appeared in the late [[Cambrian]]. The first forms had gently curved shells. During the [[Ordovician]] the group underwent an astonishing evolutionary radiation, possibly due to the new ecological niches made possible by the extinction of [[Anomalocarida,anomalocarids]] at the end of the Cambrian. Some eight new orders appeared. There was tremendous diversity among them. Some had long straight shells, short straight ones, curved, lightly coiled, and tightly coiled ones evolved. The internal structure of the shell differed greatly as well, mostly in the structure of the [[siphuncle]]. Most were probably relatively slow movers, at least compared to todays forms. The largest ones had huge straight shells that reached 3 to 5 or even 10 metres in length. All these early forms are classed under the [[paraphyletic]] and probably [[artificial taxon]] Nautiloidea ...

This site is part of the Jurassic World Heritage Coastline, so follow the Fossil Code of Conduct. This is an SSSI, so the use of hammers on the bedrock and cliffs is not allowed. In addition, the cliffs are extremely dangerous, so collecting directly from them is extremely inadvisable. However, fossils are found washed up on the foreshore and so hammers are not required.. The ammonite, Pavlovia rotunda can also be found flattened in the foreshore clays. We do not recommend collecting this ammonite, as it is too fragile and best left for others to see. Instead, try to find nodules (Rotunda Nodules), as these can contain superb ammonites, but these are not a common as they once were. However, large ammonites have been found loose, which have fallen out of boulders and many fragments can lie scattered along the beach.. If you carry on to Freshwater Steps, which is about 2.5km from the pool, the foreshore and cliff yields the crinoid Saccocoma, which is pyritised. Freshwater Steps is equal distance ...

Mantle (mollusc) - Simple English Wikipedia, the free encyclopediaMantle (mollusc) - Simple English Wikipedia, the free encyclopedia
The mantle cavity is a central feature of molluscan biology. This cavity is formed by the mantle skirt, a double fold of mantle which encloses a water space. This space contains the molluscs gills, anus, and organs for taste, excretion and reproductive organs. The mantle cavity functions as a respiratory chamber in all molluscs. In bivalves it is usually part of the feeding structure. In some mollusks the mantle cavity is a brood chamber, and in cephalopods and some bivalves such as scallops, it is a locomotory organ. The mantle is highly muscular. In cephalopods the contraction of the mantle is used to force water through a tubular siphon, and this propels the animal rapidly through the water. In other molluscs, it is used as a kind of foot for locomotion. ...

These Cenomanian representatives (Figs 3A-J, 4A-C) are all very involute at small diameters, becoming progressively more evolute as size increases. The umbilicus is ofmoderate depth, with a flattened, undercut wall and narrowly rounded umbilical shoulder. The whorl section is invariably depressed, reniform, with a whorl breadth to height ratio of 1.1 to 1.32, the greatest breadth below mid-flank in the smaller specimens. Most specimens are weathered, and show neither ornament nor constrictions. SAM PCZ022454, (ex D994) is a particularly evolute juvenile, and although rather worn, has broad, distant, linguoid ventral ribs.. SAM-PCZ022449a (ex A599) is a well-preserved internal mould 68 mm in diameter. There are 6-7 strong flexuous constrictions per halfwhorl. SAM-PCZ022458 (exD2491) is the largest specimen with the shell well preserved, and bears 6-7 distinct collar-ribs per whorl. These arise at the umbilical seam, and are prorsiradiate and flexuous, straight to feebly convex on the inner flank, ...

Types.- Holotype is UWBM74501(Figure 39.2) from Member IV, Zumaya, Spain. Paratype UWBM76079 (Figure 40.9) is from Member IV, Bidart, France. Paratype UWBM76096 (Figure 41) is from Member IV, Hendaye, France. Etymology. - Terminus (Latin), the Roman deity who presided over boundaries or landmarks. Discussion. - Anapachydiscus terminus n. sp. differs from A. fresvillensis in the much higher rib density in early and middle growth stages (more than 60 vs. 31-32, increasingto 40). Later stages are very similar in that the massive involute shell of both species has ventral ribbing only, but flank ribs persist in A. terminus at a stage where they are effacing in A. fresvillensis (compare Figure 40.9 and Figure 35.6). The high rib density immediately distinguishes A. terminus from other European Campanian Anapachydiscus, such as A. wittekindi (Schl ter, 1872) (see Blaszkiewicz, 1980, p. 50, Pl. 42, figs. 1, 2, Pl. 43, fig. 2, Pls. 44-47, Pl. 48, figs. 3, 4, Pl. 49, figs. 1, 3, Pl. 50, figs. 2, 3, Pls. ...

Preservation. The Gonatitida originated from within the more primitive anarcestine ammonoids in the Middle Devonian some 390 million years ago. The tubarium has a variable number of branches or stipes and different arrangements of the theca, these features are important in the identification of graptolite fossils. In Rhabdopleura, the colonies bear male and female zooids but fertilized eggs are incubated in the female tubarium, and stay there until they become larvae able to swim (after 4-7 days) to settle away to start a new colony. 1 GEOL 3130: PALEOBIOLOGY LABORATORY PHYLUM HEMICHORDATA SUMMARY OF CLASSIFICATION: PHYLUM HEMICHORDATA CLASS GRAPTOLITHINA ORDER DENDROIDEA Dendrograptus Dictyonema ORDER GRAPTOLOIDEA Tetragraptus Phyllograptus Didymograptus Dicellograptus Climacograptus Diplograptus Monograptus NOTE ABOUT SPECIMEN LABELS: Many of … Sato, A.
