Looks like a turtle without its shell. Are the scientists sure it didnt have a shell made of cartilage thats been lost to time?

I donβt know where this particular fella fits in the history, but turtles evolved from similar quadruped reptiles. Basically, their ribs evolved flat and wide so that their chests could support them better while burrowing tunnels. That turned into the turtle plastron.
