Introducing the #FunkyWorm, the oldest-known fossil caecilian! 220 million years ago Funcusvermis gilmorei roamed the tropical forests of Petrified Forest National Park. @PetrifiedNPS @VT_Science @vtgeosciences @AndreyAtuchin Read the paper at: https://t.co/OimkTSdb6u

Yay #FossilFriday! N is for Neoaetosauroides, an #aetosaur from the L #Triassic of Argentina. Recently Taborda et al. used FEA to support possible zoophagy/omnivory, previously proposed by Desojo, & by von Backzo et al. https://t.co/6YtiXhaL55 #Croctober #AtoZCrocs #StemCroctober

Today’s #StemCroctober is Mystriosuchus Fraas 1896. These #phytosaurs, including M. westphali & M. planirostris, have a looooong slender snout & short squamosals. A 3rd one, M. steinbergeri, was added in 2019. It's from Austria & was marine! #Croctober #AtoZCrocs #StemCroctober

Today’s #Stemcroctober is Poposaurus gracilis Mehl 1915 from the Upper Triassic of the western US. Poposaurus has a remarkably similar body plan to dinosaurs, yet has hallmarks of all pseudosuchians. We know almost the full anatomy, minus parts of the skull #Croctober #AtoZCrocs

Today’s #Stemcroctober is Nundasuchus songeaensis Nesbitt et al. 2014 a pseudosuchian from the Manda Beds of Tanzania. The phylogenetic position is poorly constrained, but largely because it lacks characters of the ‘classic’ pseudosuchian clades #Croctober #AtoZCrocs

Today’s #Stemcroctober is Desmatosuchus spurensis Case 1921, an aetosaur from the southwest. It was a one of the largest with shoulders spikes measuring ~50 cm. The diet is his unknown, but it could have been the largest herbivore of NA in the L Triassic #Croctober #AtoZCrocs
