Thecodontia (meaning 'socket-teeth'), now considered an obsolete taxonomic grouping, was formerly used to describe a diverse "order" of early archosaurian reptiles that first appeared in the latest Permian period and flourished until the end of the Triassic period. All of them were built somewhat like crocodiles but with shorter skulls, more ...
Thecodont dentition is a morphological arrangement in which the base of the tooth is completely enclosed in a deep socket of bone, as seen in crocodilians, dinosaurs and mammals, and opposed to acrodont and pleurodont dentition seen in squamate reptiles. [1] Notably, this appears to be the ancestral tooth condition in Amniota. [2]

This feature is responsible for the name "thecodont" (meaning "socket teeth"), [8] which early paleontologists applied to many Triassic archosaurs. [7] Additionally, non-muscular cheek and lip tissue appear in various forms throughout the clade, with all living archosaurs lacking non-muscular lips, unlike most non-avian saurischian dinosaurs.

The teeth are stout at the base, with slightly recurved and sharp points. [5] The first four to five maxillary teeth (anterior) are the largest at the primitive position of the canines. [5] [3] These teeth are moderately elongated, flattened, and present an obtuse apex. [3] The premaxillary and maxillary teeth are typical thecodont teeth. [8]

The 10,000 steps per day rule isn’t based in science. Here’s what experts have to say about how much you should actually walk per day for maximum benefits.
Yang classified Wangisuchus in the family Euparkeriidae, which also includes the much better known Euparkeria from the Early Triassic of South Africa. He diagnosed Wangisuchus by the following characters: long and low shape of the maxilla; pointed posterior process of the maxilla; rounded anterior margin of the maxilla; thecodont tooth implantation; crurotarsal (crocodile-like) structure of ...
