For those curious about the 3d model, it's the humerus of Pteranodon sp., FHSM VP 2183. Since this is already a fairly well described genus, I'm not gatekeeping the 3d model until publication, since this is just comparative data. Download it here:

Edmontosaurus annectens is in the news, and it made me remember of this oldie (2016) work. Something unusual tried here that got more or less confirmed from the new mummies is how a midline crest starts at the neck, and near the hips starts to transition to spikes that cover the tail!
