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 ...
This did not change when Richard Owen coined the term Dinosauria in 1842, because Owen did not recognise Thecodontosaurus as a dinosaur; in 1865, he assigned it to the Thecodontia. It was not until 1870 that Thomas Huxley became the first person to understand that it was a dinosaur, though referring it incorrectly to the Scelidosauridae. [18]
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]
Proterosuchia is one of the suborders of the paraphyletic group Thecodontia; containing the most primitive and ancestral forms. These were primitive, vaguely crocodile-like, archosauriforms that mostly lived during the Early Triassic epoch. The name Proterosuchia was coined by Robert Broom in 1906.
If the crocodilian ancestors and other Triassic archosaurs were warm-blooded, this would help to resolve some evolutionary puzzles: The earliest crocodylomorphs, e.g., Terrestrisuchus, were slim, leggy terrestrial predators whose build suggests a fairly active lifestyle, which requires a fairly fast metabolism.
von Huene (1936) named Rauisuchus in a list of the Thecodontia, [5] but no diagnosis or description was given, so it remained a nomen dubium until being properly described by von Huene (1942). [ 3 ]
The name Whippomorpha is a combination of English (wh[ale] + hippo[potamus]) and Greek (μορφή, morphē = form). [2]Some attempts have been made to rename the suborder Cetancodonta, due to the misleading utilization of the suffix -morpha for a crown group, [6] as well as the risk of confusion with the clade Hippomorpha (which consists of equid perissodactyls); [7] however Whippomorpha ...
Of note is a "Letter from the children of Moses" surfaced in mid-17th century, an episode from the numerous searches of the Ten Lost Tribes. The Letter was accompanied with the following story. A certain R. Baruch Gad, an emissary from Jerusalem to Persia was robbed on his way and after long wandering he met a warrior from the tribe of Naphtali.
