(wikipedia.org)
  • Isolated, small fossils from North America, Europe, Africa and Asia, the oldest of which were recovered from the Oligocene (Chattian) Chickasawhay Limestone (Alabama, United States), are interpreted as remains of alpheid shrimps by Hyžný et al. (wikipedia.org)
  • Mantis shrimps (order stomatopoda) are elongate crustaceans with a pair of enlarged appendages that they carry folded beneath the head, somewhat similar to the forelimbs of a praying mantis. (blogspot.co.nz)
  • Lower Cretaceous
  • 2018). An ellipsoidal chamber composed of a thin organic layer, interpreted as a likely insect cocoon or pupation chamber, is described from the Lower Cretaceous Jinju Formation (South Korea) by Lee (2018). (wikipedia.org)
  • A study on the plant specimens (ferns, gymnosperms and angiosperms) from the Lower Cretaceous Araripe Basin (Brazil) preserving evidence of plant-insect interactions and potentially of paleoecological relationships between plants and insects will be published by Edilson Bezerra dos Santos Filho et al. (wikipedia.org)
  • phylogenetic
  • 2016). A study of the eye anatomy of the thylacocephalan (an arthropod of uncertain phylogenetic placement, possibly crustacean) Dollocaris is published by Vannier et al. (wikipedia.org)
  • A study on the anatomy of the Carboniferous whip spider Graeophonus anglicus, as well as on the phylogenetic relationships of fossil whip spiders, is published by Garwood et al. (wikipedia.org)
  • mouthparts
  • Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. (wikipedia.org)
  • It is this position of the mouthparts which divides them from their closest relatives, the non-insect hexapods, which includes Protura, Diplura, and Collembola. (wikipedia.org)
  • In the adult insect the head capsule is apparently unsegmented, though embryological studies show it to consist of six segments that bear the paired head appendages, including the mouthparts, each pair on a specific segment. (wikipedia.org)
  • crayfish
  • Although Marmorkrebs have a fairly long generation time and only a "primitive" crustacean has had its genome sequenced , marbled crayfish are easily kept and reared and have a number of other reasons in their favor as a useful model organism. (blogspot.com)
  • South America
  • Another crustacean, the large acorn shell ( Balanus psittacus ), a barnacle (order Cirripedia) measuring up to 27 centimetres (11 inches) in length, is regarded as a delicacy in South America , and a stalked barnacle ( Mitella pollicipes ) is eaten in parts of France and Spain. (britannica.com)
  • appendages
  • The number and variety of appendages in different crustaceans may be partly responsible for the group's success. (wikipedia.org)
  • These animals enlarge their organs also in the adult life period and can regenerate lost appendages and organs, which is in sharp contrast to mammals and most insects. (blogspot.com)
  • adult
  • The majority of crustaceans are also motile, moving about independently, although a few taxonomic units are parasitic and live attached to their hosts (including sea lice, fish lice, whale lice, tongue worms, and Cymothoa exigua, all of which may be referred to as "crustacean lice"), and adult barnacles live a sessile life - they are attached headfirst to the substrate and cannot move independently. (wikipedia.org)
  • Jurassic
  • A study of well-preserved kalligrammatid fossils from Middle Jurassic and Early Cretaceous sites in northeastern China, indicating that kalligrammatids convergently evolved some of the anatomical traits also present in butterflies, is published by Labandeira et al. (wikipedia.org)
  • Fossil specimen which might be a barnacle nauplius is described from the Upper Jurassic Solnhofen Limestone (Germany) by Nagler et al. (wikipedia.org)
  • specimens
  • Fossil specimens of O. quadrata have been found in rocks dating from the Pleistocene. (wikipedia.org)
  • 2017). A study on the wing pad joints in several specimens of Carboniferous palaeodictyopteran insect nymphs, and their implications for the origin of insect wings, is published by Prokop et al. (wikipedia.org)
  • Patagonia
  • A study on the recovery of insect herbivores after the Cretaceous-Paleogene extinction event as indicated by insect-feeding damage on fossil leaves from the Maastrichtian and Danian localities in Patagonia (Argentina) is published by Donovan et al. (wikipedia.org)
  • Marine
  • The studied ichnocoenose corresponds in fossil records to Skolithos-Taphrhelminthopsis-Ophiomorpha-Planolites-Thalassinoides association within shallow marine Psilonichnus ichnofacies to which Uca mud-mounds are new entrants diagnostic of palaeoshoreline, especially shallow coastal-mudflats at high-tide level. (palaeo-electronica.org)
  • Marine crustaceans are as ubiquitous in the oceans as insects are on land. (wikipedia.org)
  • At the time of its discovery, Haumuriaegla was the only known fossil from the family and the only marine member. (wikipedia.org)
  • ecological
  • These modifications allow insects to occupy almost every ecological niche on the planet, except the deep ocean and the Antarctic. (wikipedia.org)
  • known
  • The scientific study of crustaceans is known as carcinology (alternatively, malacostracology, crustaceology or crustalogy), and a scientist who works in carcinology is a carcinologist. (wikipedia.org)
