A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae
The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of ...

Locomotor reassessment of Iguanodon, Ouranosaurus and Lurdusaurus (Dinosauria, Ornithopoda) using osteological correlates
Large ornithopod dinosaurs have been successively described as quadrupeds, bipeds and facultative bipeds. Here we study the case of three ankylopollexians (Iguanodon bernissartensis, Ouranosaurus nige...

Interesting preprint suggesting that recently described fossils from Brazil described as a new ctenochasmatine pterosaur, Bakiribu, preserved within a regurgitalite, instead represent the gill arch apparatus of an actinopterygian fish:

Here's a T. Rex bored to death trying to bite their own tail. My partner asked me to animate it in stop motion, after she watched a video about the very important topic of "could T. Rex chew its own tail like a dog". The puppet is still a work in progress 🦖
