This reminds me of the modern translations of the Bible that say the Behemoth in Job 40:15 is a hippo, then we read of this Behemoth in Job 40:17 and it says he moveth his tail like a cedar. Now a cedar is a really big tree, whereas a hippo has a real small tail in comparison to it's body. Translators were looking for a modern day animal to fill the bill of Job 40:15 when what it was speaking of was probably an extinct dinosaur.
@Greg Merrill it's a tempting thought that it could be a dinosaur, but is there any other evidence that they knew about dinosaurs? It reads to me more like an imagined primal beast, with attributes informed by the known big beasts of the time. Who knows?
Look up the words "dragon" and "dragons" in a Bible concordance. Sometimes they are "translated" jackal, as in Mal 1:3, but then there were "dragons of the waters" as in Psa 74:13. I doubt if those were jackals. Isaiah 27:1 speaks of a dragon, but this could be a dinosaur, Egypt or Pharaoh (Eze 29:9) or Satan (Rev 12:9). See also Psa 91:13. There are other references as well. The word "dinosaur" was not used until 1841, so people before that didn't call them dinosaurs but "dragons". Leviathan in Job 41:1,21 is probably a dinosaur as well, like the pleisosaurus.
@Greg Merrill Dragons were just one creature in a mythical menagerie - whether any of them were based on finds of dinosaur bones isn't known. It's possible.
