Colobops: a juvenile rhynchocephalian reptile (Lepidosauromorpha), not a diminutive archosauromorph with an unusually strong bite [PDF]

Royal Society Open Science, 2020
Correctly identifying taxa at the root of major clades or the oldest clade-representatives is critical for meaningful interpretations of evolution. A small, partially crushed skull from the Late Triassic (Norian) of Connecticut, USA, originally described

First three-dimensional skull of the Middle Triassic mixosaurid ichthyosaur Phalarodon fraasi from Svalbard, Norway [PDF]

Acta Palaeontologica Polonica, 2022
The marine Middle Triassic sediments of Svalbard are rich in fossiliferous material and are particularly well-known for marine reptile fossils. Here, we present a new specimen of the small-bodied mixosaurid ichthyosaur Phalarodon fraasi from the ...

The Triassic [PDF]

Current Biology, 2016
The Triassic, lasting from 252 to 201 million years (Myr) ago, was crucial in the origin of modern ecosystems. It is the seventh of the 11 geological systems or periods into which the Phanerozoic, the fossiliferous last 540 million years, of Earth history is divided.
