Dinosaurs: Shells, Horns, and Claws
Q: How did the ankylosaurus use the plates on its back?
A: Just because you have something doesn't mean you use it. For instance
you have an appendix that's not good for much of anything. But
ankylosaur plates were probably very good for blocking meat-eaters from
attacking it. It was a low, squat animal so like a porcupine, it could
probably protect its underbelly by being so hard to turn over and so
tough and pointy on the top.
Q: Did the ankylosaurus have the hardest shell?
A: Ankylosaurs had hard shells, even on their eyelids! Hard to say which
was hardest of any dinosaur though.
Q: If one of the plates on the back of stegosaurus broke off, would it
have grown back?
A: I don't think bony plates would grow back on a stegosaurus. Bones do
heal over, and there would probably be a hard lump around the broken
plate. We find dinosaurs with healed leg and rib fractures with big
lumps of bone around the break. The stegosaurus would probably have had
arthritis and maybe a backache. No kidding.
Q: Did the velociraptor really have a retractable claw like a cat?
A: Velociraptor could sweep its claw up and down in an arc, but it
wasn't really retractable into its flesh like a cat's. It was pulled up
and snapped down with the aid of muscles though, and was a nasty weapon.
