I believe that Man & Dinosaurs DID exist together at one time (most likely before the Great FLood in Noah's time).
I don't. I believe the dinosaurs and most large predators decline gave rise to hominids a little over a million years ago. Geology and Genesis are irreconcilable.
That creature in the carving may be a razorback boar, but the possibility of something else certainly is enticing.
I've also heard that in the ruins of ancient Babylon, statues and stone carvings have been found of dinosaur/sauropod like creatures with long necks and other features.
