Some others I like: Griffins, Mermaids, Dragons, Minotaur, etc.. Hell just say all of them!
I often wonder if these creatures may resemble dinosaurs or early mammals that died out. I'm sure there have been a lot of fossils our ancestors saw that have been lost to time. When the history channel runs programs dedicated to anthropology and mythology I just have to watch! I can't help it I'm a junkie for these kinds of programs. I know it may all be BS, but at least part of it is true IMO. I think most myths have some truth behind it however small. I can see someone coming across an odd fossil and it creating a few myths.
