Named Desmatochelys Padillal, it was six feet long and had the characteristic features of modern sea turtles, including a carapace or top shell and paddle-like limbs.
They're extremely valuable because of their carapaces, which are covered with big slabs of horn, thin, brown, transparent, with white and yellow markings.
It would have been difficult to capture these valuable reptiles, because they wake up at the slightest sound, and their solid carapaces are harpoon-proof.
Leatherback and softshell turtles have shells without the ring of bone around the edge of the carapace or the tough scutes covering it, making it easier for them to squeeze into tight spaces.
