I have researched Plesiosaurus and I was wondering if it lived in the
water and is it a dinosaur? Also, is a pterodactyl a dinosaur?
As far as the Plesiosaurus goes, I'm not entirely sure -- it's been a
while since I did any fossil hunting. However, I _DO_ know that the pterodactyl
is indeed a dinosaur -- since dinosaur means "terrible lizard" in Latin, and the
pterodactyl was a lizard -- it's just had wings, that's all. IT still hadn't
evolved enough to call it a bird.
