Like lizard lip

Probably not in my opinion, but maybe some species had them

I think all of them had them other then beaked dino and maybe fish eater like spino

Not all did

What ones of them didnt other then beak havers and fish eater

Dinosaurs needed a way to keep in moisture so their teeth don't wither away. So they probably had lips unless the aquatic dinosaur theory is true

Whats the aquatic dinosaur theory

More primitive dinosaurs like Eodromaeus probably didn't have lips.

But lip would be basel to them

Some probably did
