Have been using bluesky for a while to talk about #books#Dinosaurs: How They Lived & Evolved (co-authored with Prof Paul Barrett). Three editions published so far and it continues to sell well. Let me know if you own it and like it!
Edmontosaurus annectens 🦆✨️ #paleoart#edmontosaurus#hadrosaur#ornithischian#dinosaurs#digitalart#art
admitting that my understanding of ornithischian taxonomy is lacking
Skeletal reconstruction of Thescelosaurus neglectus, a robustly built, somewhat basal ornithischian
Although one of the tooth roots is broken off in this specimen, for tiny teeth, a derived double root distinguishes common triceratopsin teeth from the basal single root of the small and much rarer Leptoceratops. #dinosaur#fossil#paleontology#triceratops#torosaurus#ceratopsian#ornithischian
While Edmontosaurus annectens material is very commonly available to collectors, it's almost entirely from the Hell Creek or Lance Formation. So a nice tooth crown from the similarly aged Laramie Formation is quite unique. #dinosaur#fossil#paleontology#edmontosaurus#ornithopod#ornithischian
"Qianjiangsaurus changshengi lived... during the Late Cretaceous epoch, around 70 million years ago. The 8-m... long herbivore belongs to Hadrosauroidea, a superfamily of ornithischian dinosaurs that includes the so-called duck-billed dinosaurs & their close relatives." www.sci.news/paleontology...
A new genus and species of non-hadrosaurid hadrosauroid dinosaur, named Qianjiangsaurus changshengi, has been identified from a specimen found in 2022 in southwest China.
Too big in overall size, or longer? If longer it might just be less worn, or like you say, it could be another ornithischian. But I don't think we have a good handle on tooth variation between different species within a family yet. If it's previously undocumented, it may not perfectly match.
