Quill knobs! When present, they indicate large wing feathers. BUT, some birds (ostriches, rheas, ducks) have large wing feathers without quill knobs, so their absence doesn’t mean dinosaurs without them were wingless #FossilFriday

Happy Deinonychus Day!
UAlberta student @MarkPowersJ’s thesis outlined a new, short-snouted skull shape for Deinonychus - turns out what was thought to be part of the maxilla was actually the premaxilla!

late #FossilFriday, spent yesterday doing a quick photogrammetry of a cast Albertosaurus skull. The re-assembled skull will be used for an updated illustration from my 2020 drawing

In bipedal animals, one femur has to support the entire weight of the animal during locomotion. Because of that, the width of the femur can predict the animal's mass.
This was extended to bipedal dinos in Campione et al. 2014 (great paper btw, link: https://t.co/9WygG7XuF4)
