Is There a Dragon in the Bible?

According to pliny the elder, the unicorns were a beast that was very large and furious. People have drawn images of it based on what he says about its physical characteristics. There's also thought now that the griffin myth may be based on proto saratops fossils. And trolls are presented as basically human, but as wild, savage people who aren't christians. So there could be a naturalistic basis for that.
