And now for the second day of #temnovember, we have #Acroplous, an a basal dvinosauroid from lower permian of northamerica, known from multiple localities and specimens

#temnovember2025 day 3: Tupilakosaurus
Third day of #temnovember and hey look at that, we have the name shake of a family,#Tupilakosaurus , the tupilakosaurids are small and long dvinosaurs from the early #Triassic

Uliakhin & Golubev described a new dvinosaur, Dvinosaurus gubini, from the late Permian of Russia, based on disarticulated cranial elements. This probably results from the smaller size relative to other species (i.e. immaturity, unfortunately they cite size as diagnostic). doi.org/10.1134/S003...

#temnovember2024 day 2: Neldasaurus
Second day of #temnovember and we have the basal dvinosaurid #neldasurus, a mid size aquatic #temnospondyl from the permian of northamerica
#paleoart #sciart #amphibian #dvinosaurus #permian

Next one (by Efremov) concerns discovery in the same Bogdo locality (Late Permian of the Kirghiz ASSR) of Trematosaurus and Capitosaurus, and a theory about Dvinosaurus being a neotenic form of temnospondyl owing its survival in Late Permian to non-migratory patterns

A painted 3d print of a dvinosaurus skull, done for the prompt 'extinct'.  I printed it small because I was trying to do this prompt in a day; but I've since printed a larger one.
