The Croc That Ran on Hooves

  • Published on: 01 May 2019
  • Our Pocket Shirt!:

    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?

    Maybe is had short front legs so it could reach the ground better because in the photos the head and neck looked very close to a modern crocs and the snout looked to long for it to directly reach the ground I dont think they could turn their head directly facing the ground to eat
