I had an educational book about dinosaurs in the early 90's that was pretty factual and accurate, but then at one point it veered off into this completely bonkers idea about how Troodon might have evolved into a human if it hadn't gone extinct. it had a model

it could have ended up as a bipedal sapient creature, but like, human shoulders are the shape they are because our ancestors swung from trees, etc. a dinoman would not have arms like ours.

or hips like ours. why would he lose his tail. etc. etc.

Wait wtf why does it have a BELLYBUTTON

I'm 90% sure this was the book
