Ornithomimids/Ornithomimosaurus September Part one Anserimimus Tuesday

It's September, a brand new mouth with new dinosaurs. Dino Lord's gonna give new dinosaurs all September long and it's not gonna stop there so i give the birds mimic dinosaurs the Ornithomimosaurus starting with Anserimimus the goose mimic dinosaur.

Anserimimus was three meters long and was toward the smaller end of the scale in Ornithomimosaur size. Other related dinosaurs like Gallimimus  would have been double its size and the incomplete Deinocheirus would have been larger. It's most likely that these variations in total size were down to each genus taking up a different position in the ecosystem, growing to size that allowed them to best fit their roles. Anserimimus is most different to other ornithomimids by the structure of the arms which are powerfully built with almost straight claws that are only slightly curved growing from the fingers.‭ ‬The actual hand bones themselves were fused which resulted in the hand being stiffened to maintain its shape.‭ ‬It would seem that this hand and arm structure evolved for a very practical and physical purpose given the much stronger development,‭ ‬but how and why this worked is still unknown for certain.
