Description
The scattered vertebrae of anthracosaurs from the late Carboniferous - the early Permian of North America were described under the name Cricotus (the genus was isolated by E. D. Kop in 1884 ). Later, these remains were recognized as non-diagnostic, for the most complete finds (including complete skeletons) E. Case presented the name Archeria in 1915.
By its structure, the archeria is a typical anthracosaur embolomer, with a long body, short limbs and a very long tail. The spinous processes of the caudal vertebrae are high, the supraneural radials form a “tail fin ”. The fore and hind limbs are five-fingered, the forepaws are significantly smaller than the hind. The pelvis is massive. The skull is low, with a long muzzle, the lower jaw is high. The teeth are very small. Well developed grooves "sideline". Archeria is perhaps the most studied anthracosaurus and its skeleton used to reconstruct other anthracosaurs.
The type species is Archeria crassidiscus , another 2-3 species are not excluded ( Archeria robinsoni , Archeria victori ). The length of the skull is from 20 to 35 cm, which implies a total length of the animal up to 2 meters. Judging by the small teeth and the long muzzle, the animal ate small prey ( amphibian larvae, small fish ). The genus is known from the very beginning of the Permian to the upper horizons of the early Permian in Texas and New Mexico (Wichita Formation).
Archeries - one of the last anthracosaurs.
Title
The name is given in honor of Archer County, Texas (USA), where the most complete remains are known.
Archeria is the scientific name of not only the genus of extinct amphibians, but also the genus Archeria of flowering plants from the heather family ( Ericaceae ). Since the zoological genus Archeria is under the jurisdiction of the International Code of Zoological Nomenclature , and the botanical genus Archeria is within the jurisdiction of the International Code of Botanical Nomenclature , these names are not taxonomic homonyms and the procedure for eliminating homonymy should not apply to them.
