    In the Eocene Epoch, there was a reptile that had teeth equipped for biting through flesh, its hind legs were a lot longer than its front legs and instead of claws, its toes were each capped with hooves. How did this living nightmare come to evolve?

    Sure... The "Lizard People" don't want us to suspect that this creature could run on hind legs, because that would lead to questions...... questions they don't want answered!

    Ok but what about a horse that swam like a crocodile. Webbed hooves and a long scaley tail.

    why has everyone forgotten about Kaprosuchus, a croc that could gallop, and even rearup on its back legs and swipe with 4inch razor clawsoh and I forgot about its 3 inch fangs that gave it its name

    Most all creatures “just showed up” in the fossil record. Your looking at the fossil record wrong. It’s not like a book being read for understanding. Sorry it’s just not like that.

    Why do people like you use the word fodder so much. Do you also "geek out" about beer?

    A lot of quadrupedal lizards do "pop a wheelie" for the first few strides of a sprint for better acceleration. That's probably what this animal did, and why it has those big back legs.

    This monster might have been able to sprint metres at a time by pushing off the ground with its rear legs but I doubt it can run - too heavy and the rear legs are not big and long enough to walk on full-time.
