the pachycephalosaurus was a dinosaur that had a hard bony skull, and probably a strong neck for it.
they appeared at the end of the cretaceous, were presumed plant eaters, and fulfilled a ecological niche presumably similar to elk or bighorn sheep. the males probably used their hard skulls to crash into each other to win females in the herd, much like most modern goats do.
there are many other dinosaurs that have hard heads (ceratopsians come to mind) and others with long, and presumably strong necks (sauropods). we could say that the tyrannosaur has a strong neck.
so your question is a bit vague. i hope this answer leads you to something that helps you out!
Many types of dinosaurs head crests. Some were hadrosaurs, such as Parasaurolophus, Corythosaurus, and Saurolophus. Others were theropods, such as Ceratosaurus or Allosaurus.
Tricerotops.
He could probably be some kind of hadrosaur due to the crest on his head, but then again, it's probable he could also be an iguanodon to his physical appearance.
depends what kind of dinosaur it is but probably the dinosaur
Rhamphorhynchus was a pterosaur, not a dinosaur.
