2012年10月30日 · Reptiles. Reptiles (Reptilia) have an abundant fossil record in this period. The display includes: a slab with small reptile footprints, A mounted specimen of a lizard sized Captorhinus aguti, a member of the extinct captorhinids (Captorhinidae<Romeriida<Reptilia). These primitive reptiles were a closely related sister-group to the diapsids ...

One of the best known early reptiles is Mesosaurus, a genus from the Early Permian that had returned to water, feeding on fish. The earliest reptiles were largely overshadowed by bigger labyrinthodont amphibians, such as Cochleosaurus, and remained a small, inconspicuous part of the fauna until after the small ice age at the end of the ...

2000年11月3日 · We report here on the discovery of a small, nearly complete skeleton of an Early Permian reptile whose skeletal anatomy indicates a capability to attain relatively high speeds during bipedal and quadrupedal locomotion using a parasagittal gait and digitigrade stance.

2017年3月17日 · During the Permian period, pelycosaurs and therapsids occupied the mainstream of reptile evolution--but there were also plenty of bizarre "one-offs," chief among them the creatures known as pareiasaurs.

Other important reptile groups from the Permian include the anapsids (e.g. captorhi-nomorphs) and primitive diapsid reptiles, whose descendants were to dominate the course of reptile evolution to the present day.

The most primitive groups of diapsids went extinct at the end of the Permian (Dixon, 1988, p. 84). The first synapsids were the pelycosaurs, which made up 70% of the vertebrate terrestrial fauna in the early Permian.

2014年2月8日 · Two important groups of animals dominated the Permian landscape: Synapsids and sauropsids. Synapsids had skulls with a single temporal opening and are thought to be the lineage that eventually...

2018年6月13日 · Here, we place all known middle Permian–early Late Triassic archosauromorph species into an explicit phylogenetic context, and quantify biodiversity change through this interval.

Two new reptile skulls from the Richards Spur locality, Lower Permian of Oklahoma, represent a new diapsid reptile: Orovenator mayorum n. gen. et sp. A phylogenetic analysis identifies O. mayorum as the oldest and most basal member of the araeoscelidian sister group.
