Microraptor

My second choice would be darwinopterus

Pachyrhinosaurus

I would want a loyal Utahraptor by my side through the tough times. Probably not a disloyal one though.

Megaraptor cause it's cool

Protoceratops, Archaeoceratops or Psittacosaurus, not just because I like them, but also because they look cool and are potentially easy to care for.

We can probs ride proto

Wait, is that a tyrannosaurid? HOLY ANCESTORS OF ORNITHOPODA, GO THE HECK BACK!!!

A fully grown man or woman probably couldn't ride a proto
