Of course there isn’t. I was just being polite. I thought he or she might post a link to some cave painting of a bison or something that had been misinterpreted as a dinosaur.
I have always believed, however, that tales of dragons came from the discoveries people made of dinosaur bones. Dinosaur and dragon really seem like two different names for the same creatures. If you came across the skeleton of a dinosaur of any kind, you’d have no trouble at all figuring out what it looked like. We have no trouble recognizing animal skeletons found in the woods today, for instance.
You're kidding right? Animal remains are fairly regularly reported as human until they can be excluded by laboratory tests. Bear paws are frequently confused with human hands...
