Again, I'm just floored (so is the person in the photo!) by this kind of thing. To think such gigantic reptiles once populated this planet, for realsies. I mean if that doesn't sound like something out of the most way out kind of science fiction. And yet we had no idea such creatures existed until fossils began turning up around the 1820s.
Can you imagine what kind of plays Shakespeare would have written about dinosaurs if he'd known about them? But even suggesting that thunder lizards once existed on earth would probably have landed you in the stocks back then.
