When did and why did dinosaurs go from giant fangs to beaks? Or are reptiles more direct descendants of those dinosaurs

[–] [email protected] 1 points 2 days ago

Fangs are still pretty rare in reptiles. Most lizards have basically some form of serrated beak.

fwiw there were plenty of non-avian dinosaurs with beaks, ceratopsids for one.

Birds are the only direct descendents of dinosaurs. Reptiles were around at the same time as dinosaurs and evolved independently. There are huge differences, scales instead of skin and feathers, cold blooded instead of warm, etc.

Why Do Birds No Longer Have Teeth?

TL;DR: Beaks are a lot lighter and more easily adapted than teeth.
