That upright dinosauroid was a textbook case of humanoid chauvanism. They had a perfectly good bipedal form with grasping hands to begin with, thank you very much.
Here they've been given essentially a perfect human skeleton, with only the fingers, toes and skull differing. Pure nonsense! The barriers to that evolutionary direction are huge, and the destination of sapience from the dinosaur form has so many easier routes. Incidentally, two groups of dinosaurs have almost got there now: the Passerines have produced the crows and the psittacines have produced the macaws, greys and amazons.
One of my favourite palaeoartists Nemo-Ramjet produced a more realistic alternative to the humanoid dinosauroid, inspired by ground hornbills
And even gave them cave art, drawn with authentic tools and media using his teeth and hands held the way his creatures do.
He did, as revisiting the humanoid dinosauroid, try producing an authentic upright posture, but this was as close has he could justify.
