A modern human pattern of dental development in lower pleistocene hominids from Atapuerca-TD6 (Spain). (1/163)

The study of life history evolution in hominids is crucial for the discernment of when and why humans have acquired our unique maturational pattern. Because the development of dentition is critically integrated into the life cycle in mammals, the determination of the time and pattern of dental development represents an appropriate method to infer changes in life history variables that occurred during hominid evolution. Here we present evidence derived from Lower Pleistocene human fossil remains recovered from the TD6 level (Aurora stratum) of the Gran Dolina site in the Sierra de Atapuerca, northern Spain. These hominids present a pattern of development similar to that of Homo sapiens, although some aspects (e.g., delayed M3 calcification) are not as derived as that of European populations and people of European origin. This evidence, taken together with the present knowledge of cranial capacity of these and other late Early Pleistocene hominids, supports the view that as early as 0.8 Ma at least one Homo species shared with modern humans a prolonged pattern of maturation.  (+info)

Australopithecus garhi: a new species of early hominid from Ethiopia. (2/163)

The lack of an adequate hominid fossil record in eastern Africa between 2 and 3 million years ago (Ma) has hampered investigations of early hominid phylogeny. Discovery of 2.5 Ma hominid cranial and dental remains from the Hata beds of Ethiopia's Middle Awash allows recognition of a new species of Australopithecus. This species is descended from Australopithecus afarensis and is a candidate ancestor for early Homo. Contemporary postcranial remains feature a derived humanlike humeral/femoral ratio and an apelike upper arm-to-lower arm ratio.  (+info)

Equatorius: a new hominoid genus from the Middle Miocene of Kenya. (3/163)

A partial hominoid skeleton just older than 15 million years from sediments in the Tugen Hills of north central Kenya mandates a revision of the hominoid genus Kenyapithecus, a possible early member of the great ape-human clade. The Tugen Hills specimen represents a new genus, which also incorporates all material previously referable to Kenyapithecus africanus. The new taxon is derived with respect to earlier Miocene hominoids but is primitive with respect to the younger species Kenyapithecus wickeri and therefore is a late member of the stem hominoid radiation in the East African Miocene.  (+info)

A new primate from the Middle Eocene of Myanmar and the Asian early origin of anthropoids. (4/163)

A new genus and species of anthropoid primate, Bahinia pondaungensis gen. et sp. nov., is described from the Yashe Kyitchaung locality in the Late Middle Eocene Pondaung Formation (Myanmar). It is related to Eosimias, but it is represented by more complete remains, including upper dentition with associated lower jaw fragment. It is interpreted as a new representative of the family Eosimiidae, which corresponds to the sister group of the Amphipithecidae and of all other anthropoids. Eosimiidae are now recorded from three distinct Middle Eocene localities in Asia, giving support to the hypothesis of an Asian origin of anthropoids.  (+info)

Widanelfarasia, a diminutive placental from the late Eocene of Egypt. (5/163)

The lower dentition of Widanelfarasia (new genus), a diminutive late Eocene placental from the Fayum Depression in Egypt, is described. Widanelfarasia exhibits a complex of features associated with incipient zalambdodonty and at least three unequivocal apomorphies [loss of P(1), an enlarged I(2) (relative to I(3)), and a basal cusp on I(2)], which provide weak support for its placement as a possible sister taxon of either a tenrecid-chrysochlorid clade or of solenodontids. The former hypothesis gains additional support from biogeographical evidence, but both scenarios are currently tenuous as Widanelfarasia is clearly not truly zalambdodont. Phylogenetic hypotheses positing affinities with tenrecids alone or chrysochlorids alone must invoke either convergent acquisition of zalambdodonty in these taxa or autapomorphic reversal in Widanelfarasia. Given these considerations, a relationship with more generalized taxa from the Laurasian Paleogene (e.g., geolabidids, nyctitheriids, leptictids) cannot yet be ruled out. Comparisons with other Paleogene Afro-Arabian forms are generally inconclusive. A relationship with the earlier Eocene Chambilestes from Tunisia-currently represented by a single specimen preserving P(4)-M(3)-seems possible based on the geometry and predicted occlusal relationships of these teeth, but cannot be confidently determined until these two taxa come to be represented by common diagnostic elements. Todralestes (late Paleocene, Morocco) exhibits general phenetic similarities to Widanelfarasia, but it is not yet known whether this taxon shares any of Widanelfarasia's unequivocal dental apomorphies. Pending the recovery of more informative material, we tentatively refer Widanelfarasia to Placentalia incertae sedis. Truly zalambdodont placentals remain conspicuously absent from the Paleogene of Afro-Arabia.  (+info)

Linking development with generation of novelty in mammalian teeth. (6/163)

The evolution of mammalian teeth is characterized by the frequent and convergent evolution of new cusps. The evolution of new cusps can be linked to tooth development via population-level variation. This allows testing whether development increases the capacity to evolve, or evolvability, by facilitating and even directing morphological change. In a population sample of living seals, variation in cusp number of individual teeth is from three to five cusps, the variably present cusps being the shortest ones that also develop last. By factoring in recent evidence on development, I show that the variation in cusp number can be explained by a patterning cascade mode of cusp development that cumulatively increases and directs height variation in short cusps. The biased variation in seal tooth cusps supports the recognition of teeth as highly evolvable because only small developmental changes are needed to produce large changes in size and number of small cusps. This evolvability of tooth cusps may have facilitated the fast and independent acquisition of new cusps in mammalian evolution. In phylogenetic studies, small cusps may be unreliable as phylogenetic signals. Population level variation can be a powerful tool in testing and generating hypotheses in developmental evolution studies.  (+info)

Oral hygiene, dentition, sexual habits and risk of oral cancer. (7/163)

In an Italian case-control study of oral cancer, number of missing teeth and other aspects of dental care were similar, but the general condition of the mouth, as indicated by gum bleeding, tartar deposits and mucosal irritation, was worse among oral cancer cases than controls. No differences were detected in sexual practices (including oral sex) and (previous) sexually transmitted infections.  (+info)

Dynamics of tooth formation and replacement in the zebrafish (Danio rerio) (Teleostei, Cyprinidae). (8/163)

We have used three-dimensional reconstructions from serial sections as well as cleared and stained specimens to infer patterning of the pharyngeal dentition throughout ontogeny in the zebrafish. Each pharyngeal tooth has been monitored from its initiation to its complete disappearance (resorption and shedding). We have identified tooth families and have studied the persistence of the pattern through successive replacements. Teeth arise in two seemingly independent clusters, a ventral and a dorsal cluster, with differing patterning features. The ventral cluster consists of one row of five teeth in which a tooth is first initiated in position four, and subsequent teeth in adjacent positions, posterior and anterior to it. Replacement teeth in odd and even positions are initiated simultaneously during successive odontogenic waves but differ in generation number according to the timing of appearance of the first-generation tooth, i.e., the founder of the tooth family. Up to four teeth of a single tooth family are simultaneously present in early juveniles of which two are usually "co-functional." The number of teeth per tooth family is reduced in older juveniles and adults, reflecting a slowing down of the replacement rate. The consistent way in which the pattern is established and maintained during ontogeny calls for research of the presence of specific molecular controls.  (+info)

Conodonts are chordates that resembled eels. The entire class of conodonts was wiped out by the Triassic-Jurassic extinction event, which occurred 200 million years ago.. Researchers used X-rays to create computer models of the eight paired, food-processing structures from fossils of the Wurmiella excavata. The tips of the teeth are just 2 micrometers across. Using finite-element analysis, which uses numerical analysis to approximate the solutions of partial differential equations, the scientists compared conodont teeth with similar-sized bat molars. The findings were published in the journal Proceedings of The Royal Society B.. Conodonts relied on minuscule forces that were concentrated because of the extreme sharpness of their teeth. They didnt use muscular force as mammals do and conodont teeth sliced from left to right, instead of up and down. The sharpness would have made the teeth brittle, but conodonts may have been able to re-sharpen them, a quality that other vertebrates have failed to ...

Several well-preserved jaws of the rare North American omomyid primate Steinius vespertinus, including the first known antemolar dentitions, have been discovered in 1989 and 1990 in the early Eocene Willwood Formation of the Bighorn Basin, Wyoming. They indicate that its dental formula is as primitive as those in early Eocene Donrussellia (Adapidae) and Teilhardina (Omomyidae) - widely considered to be the most primitive known euprimates - and that in various dental characters Steinius is as primitive or more so than Teilhardina. Therefore, despite its occurrence at least 2 million years later than Teilhardina, S. vespertinus is the most primitive known omomyid and one of the most primitive known euprimates. Its primitive morphology further diminishes the dental distinctions between Omomyidae and Adapidae at the beginning of the euprimate radiation.

What is Mixed Dentition? Mixed Dentition is the situation when both deciduous and permanent teeth are present. Save on dental care procedures with a dental plan.
A positive mold for use in creating an orthodontic appliance is produced by obtaining a digital dentition model, such as a 3D geometric surface model or a 3D volumetric image model, that defines the shape of an orthodontic appliance and then altering the digital dentition model to remove a portion that does not affect the shape of the orthodontic appliance. The altered digital dentition model then is used to construct a positive mold for the orthodontic appliance. Processing circuitry, such as a programmed computer, is used to obtain and alter the digital dentition model. A rapid prototyping device, such as a stereolithography machine, is commonly used to construct the positive mold.
The fossil record of conodonts may be among the best of any group of organisms, but it is biased nonetheless. Pre- and syndepositional biases, including predation and scavenging of carcasses, current activity, reworking and bioturbation, cause loss, redistribution and breakage of elements. These biases may be exacerbated by the way in which rocks are collected and treated in the laboratory to extract elements. As is the case for all fossils, intervals for which there is no rock record cause inevitable gaps in the stratigraphic distribution of conodonts, and unpreserved environments lead to further impoverishment of the recorded spatial and temporal distributions of taxa. On the other hand, because they are resistant to abrasion and can withstand considerable metamorphism conodonts can preserve evidence of otherwise lost sequences or environments through reworking.. We have conducted a preliminary investigation into how the various forms of gross collecting bias arising from period to period ...

Like other members of its family, Microgale gracilis retains many primitive traits, including a low and seasonally variable body temperature, a cloaca (common opening for the urogenital, anal and reproductive tracts) and testes that are undescended in the male. Microgale gracilis is shrew-like in appearance and many of its morphological features suggest that it is semi-fossorial. This species is characterized by an elongate skull, long rostrum and rhinarium, dense, velvety pelage, reduced eyes and ears, short forelimbs with broadened forefeet, and enlarged claws with five digits. The tail is shorter than the head/body length. Individuals have dark-brown dorsal pelage with buff speckles, and dark grey ventral pelage with a buff wash. The tail is bicoloured, dark brown dorsally and light brown ventrally. Juveniles appear less speckled than adults, particularly posteriorly. The dentition is much reduced in size with slender canines and incisors. The adult dental formula of M. gracilis is I3/3, ...
Trechnotheria is a group of mammals that includes the therians and some fossil mammals from the Mesozoic Era. In the Jurassic through Cretaceous periods, the group was endemic to what would be Asia and Africa. Trechnotheria has been assigned various ranks, but was originally called a superlegion by the original author. One reference has defined the Trechnotheria as the clade comprising the last common ancestor of Zhangheotherium and living therian mammals, and all its descendants. Like most Mesozoic mammal groups, early trechnotherians are known mainly from their teeth. Hence, one of the most prominent features of this group is the hypertrophied postvallum/prevallid shearing mechanism, along with other dental characters. Features of the shoulder blade, tibia, humerus, and ankle joint also diagnose this clade. A cladogram compiled by Mikko Haaramo and based on individual cladograms of after After Luo, Cifelli & Kielan-Jaworowska, 2001, Luo, Kielan-Jaworowska & Cifelli, 2002 and, ...
But maybe the show could have retained some use if all of this human-like/fictional appearance and behavior was there to illustrate some greater true scientific fact, that even network execs think viewers could remember. Alas, no. The implication of the Eoraptor portion was that dinosaur success was due to more complex parental care, but my impression has been that evidence for such care is limited to maniraptorans, supposed evidence for care in hadrosaurs (and thus Ornithischia) has been refuted, and that baby sauropods were too small to associate with adults and arent apparent in herd trackways. And even the mosasaur cares for its babies enough to get revenge on sharks for eating them (vengeance is such a widespread trait in squamates...). As does the Cretaceous mammal, more realistically. If you want to make the point dinosaurs were probably often brightly colored with display structures as the Gigantoraptor portion tries to, a far superior method would be to show say ten different ...
How to Regain Good Dental Formula. There is a significant portion of the country population who have had to persevere dental related appearance challenges. Stained dentals and poor arrangement of teeth are just but some examples of the abnormalities. Failure to understand that the problem can be solved is the primary reason many people have accepted to live with those conditions. Price consideration has also forced a significant number to shy away from visiting dental experts often giving away ones health for money.

Nesomyines are characterized by their morphological and ecological diversity. Typically they are medium to large gerbil-like, vole-like, or rat-like rodents. They measure 80 to 350 mm in head and body length and their tails range from 60 to 250 mm. Nesomyines weigh 21 to 1,500 grams. In some species, females weigh less than males, in other species, there is no sexual dimorphism. Nesomyine tails are short to long, naked to moderately furred, and sometimes tufted. Some have prehensile tails. The hind feet range from wide and short to narrow and long, and most have no hair on the soles. The pelage is long and soft or thick and woolly. It is sandy brown, reddish, or gray on the dorsum and yellowish white, white, or gray on the venter. Most nesomyines have large eyes and prominent ears and whiskers.. The nesomyine dental formula is 1/1, 0/0, 0/0, 3/3 = 16. The incisors are opisthodont. The molars are rooted, have a biserial cusp arrangement, and range from brachydont to hypsodont. In most species, ...
With the exception of the maras, which have a more rabbit-like appearance, caviids have short, heavy bodies and large heads. Most have no visible tails. They range in size from the smaller cavies at 22 cm in body length, and 300 grams in weight, up to the capybara, the largest of all rodents at 106 to 134 cm in length, and body weights of 35 to 66 kilograms. Even larger forms existed in the Pliocene, such as Phugatherium, which was about the size of a tapir.[1] They are herbivores, eating tough grasses or softer leaves, depending on species. The dental formula is similar to that of various other rodents: Females give birth to two or three furred and active young after a gestation period of 50 to 90 days in most species, or 150 days in the capybara. In most species, they are sexually mature within a few months of birth, although in capybaras, maturity is not reached until around 18 months.[2] Social organisation varies widely among the group. Many cavies are promiscuous, forming ...

Views of the dentition can only be achieved using dental retractors as it is necessary to retract the cheeks and lips from the field of view in order to obtain clear intra-oral pictures. Dental retractors are available in metal, wire and plastic and come in paediatric and adult sizes. Dental retractors (if used properly) should provide both vertical clearance as well as horizontal retraction of the lips. Dental mirrors can be used alongside retractors, the mirrors are available in glass and plastic and also in paediatric and adult sizes. There are two main types of dental mirrors, occlusal mirrors are designed to fit inside the patients mouth. The occlusal mirror can be tilted until the reflection of either the upper or lower dentition is visible, the photographer can then photograph the reflected image of the maxillary or mandibular arch. Buccal mirrors are used when photographing the buccal surfaces of the posterior teeth. Buccal mirrors are often double ended and the smaller side can be used ...

The morphology of the lower jaw and teeth of the legless lizard Pseudopus apodus (Anguimorpha, Anguidae, Anguinae) from Eurasia are described in detail and compared with those of other species of the subfamily Anguinae. The lower jaw anatomy of Pseudopus, especially the dentary and teeth, clearly differs from the genera Ophisaurus and Anguis. Even so, Ophisaurus is largely uniform in its lower jaw morphology across species. The teeth of North American Ophisaurus are slender cylinders, the shafts are mesiodistally compressed and bulge lingually; the apices are curved lingually and posteriorly and have weakly developed cutting edges. Southeast Asian and North African Ophisaurus present conical teeth, with broadened bases, apices more distinctly curved lingually and posteriorly, and cutting edges that are distinctly developed. The lingual surfaces of the tooth apices are striated in Ophisaurus and Pseudopus. The lower jaw of Ophisaurus is in many respects similar to that in Anguis, however, the ...
Evidence suggests that energy-protein malnutrition is associated with impaired growth and development of facial bones. The objective of this study was to investigate the association between nutritional status and reduced space for dental eruption (crowding) in permanent dentition. A cross-sectional study with probabilistic sampling design was used. We evaluated 2,060 students aged 12 to 15 years enrolled in schools in the northeast of Brazil. Crowding was defined according to World Health Organization (WHO) as misalignment of teeth due to lack of space for them to erupt in the correct position. Nutritional status was evaluated by means of body mass index and height-for-age, using the WHOs reference curves. Parents and adolescents responded to a questionnaire about demographic, socioeconomic, biological and behavioral characteristics. The associations were estimated by odds ratio (OR) in multivariate logistic regression analysis (alpha = 0.05). Confounding and effect-modification were taken into account
Eruption is a complicated process where teeth begin to appear through the gums.Humans have 2 sets of teeth, namely primary dentition and permanent dentition.Primary dentition consists of 20 baby teeth and erupts when infants are around 6 months of age. Permanent dentition consists of 32 teeth which starts erupting at the age of 6 years old ...
The Soom Shale is perhaps most famous for conodonts. The remains of this taxon exemplify the quality of preservation, the unusual composition of the fossils and that Soom taxa are often anatomically peculiar members of their kind. Conodonts are mostly represented in the fossil record by millimetre-sized phosphatic elements recovered after acid preparation of rocks from Cambrian to Late Triassic age; they are the teeth of otherwise nonbiomineralized jawless fish (Aldridge et al. 1986). Rarely, these phosphatic elements occur as natural assemblages reflecting the morphology and topology of the conodont tooth-set, albeit collapsed into two dimensions on the bedding plane. The Soom Shale preserves hundreds of bedding plane assemblages of conodonts, which can be seen on the shale surface with the naked eye. All are from the priniodontid order; those of the taxon Promissum pulchrum form a significant proportion of the fossils collected from the Lagerstätte (Aldridge et al. 2013). They are both the ...

Conodont biostratigraphy of the upper Montney and Doig formations in the subsurface of northeastern British Columbia provides the first age constraints on the boundary between these two formations. Previously presumed to be broadly but uniformly equivalent to the Spathian-Anisian boundary, it is shown herein to be highly diachronous, ranging from Spathian to Middle Anisian in age. It is oldest in the Altares area (at 56.201389 N; 121.906667 W) and youngest in the Dawson area (at 55.846389 N; 120.203333 W). The fact that the Montney-Doig boundary is oldest in the centre of the study area and younger in all directions suggests that the basal Doig Formation does not represent simple west-east transgression as previously thought. Rather, the Doig Formation was apparently deposited in the Altares region first and transgression must have proceeded away from this point. The lowest part of the Doig Formation, the Doig Phosphate Zone, has long been recognised as a condensed horizon. However, it is not ...
Abstract The general principles guiding the study of wear facets which develop during mastication in mammals possessing tribosphenic molars are named. The application of this method of study to the molars of European Tertiary Didelphidae shows that the lineage of this family as represented by the species Peratherium cuvieri (Upper Eocene), P. elegans (Lower-middle Oligocene) and P. antiquum (Upper Oligocene) has propessively evolved toward a more carnivorous diet. ...
During any anesthetic, especially during General Anesthesia, it may be necessary to place life sustaining, and life saving airway devices. Be aware that no dental restoration, cap, crown, bridge, implant, partial, denture or any other unnatural dental work present, is as sound or strong as natural dentition. It is thus possible that during placement of the aforementioned devices, and perhaps even more commonly, during involuntary emergence biting down, that the dental work can be damaged. Despite the anesthesiologist taking utmost care to protect your dentition, situations may arise, out of his / her control, that could lead to dental damage. Similarly, unsound natural dentition are prone to the same risks. We encourage our patients to disclose all dental work and dental conditions, so that optimal protection can be put in place. ...

Mandible is the scientific term for the lower jaw. Whereas we humans have a lower jaw made of only a single bone (the dentary), penguins have a more complicated mandible made up of half a dozen different elements (the dentary, splenial, articular, prearticular, angular and surangular). These bones are all connected in penguins, though some…

The conodont-based biochronology of the Devonian Period is calibrated herein on the basis of: (1) a recent, reliable radiometric dating (CLAQUE??-LONG et al. 1992) of a stratigraphic position just above the Devonian-Carboniferous boundary; and (2) new calculations of stage durations based on our estimates and those of a large number of other Devonian workers, which pertain to many stratigraphie sequences in several different paleotectonic settings globally. Using these tools we maintain the 46-m.y. duration for the Devonian Period given by the recent global timescale (GTS 89) of HARLAND et al. (1990). The main changes to GTS 89 are accomplished by raising the dating of the end of the Devonian by 9 m.y. from 363 Ma to 354 Ma and considerably shortening the bizarre estimate given by GTS 89 for the length of the oldest two Early Devonian stages. We reiterate our earlier expose?? (ZIEGLER & SANDBERG 1994) of the inaccuracies...
I am indebted to my friend Mr. A. N. Leeds, of Eyebury, near Peterborough, for the opportunity of bringing under the notice of the Society a very interesting, although unfortunately imperfect, Dinosaurian jaw, recently obtained from the brick-pits in the Oxford Clay near the town named.. The specimen comprises the anterior and posterior extremities of the left ramus of the mandible, showing the alveoli of the teeth and the cavity for the articulation of the quadrate. The fractured surfaces are fresh, and it is thus evident that the present imperfect condition of the specimen is due to a blow from the pick of the workman by whom it was disinterred. When entire, its total length was probably about 1 foot. The anterior fragment (Pl. XI. figs. 1, 1 a)comprises the greater portion of the dentary bone, with the symphysis entire; while the hinder moiety (ibid. figs. 2, 2 a) includes the articular, and portions of the angular and surangular elements.. The dentary bone is somewhat roughened and pitted on ...
