Proganochelys quenstedti |
Proganochelys fossils have been found in Germany and Thailand, and they show that this was a creature around 1m long. They look remarkably like the turtles that we have today, and even shed some light on how turtle got to be how they are.
Since it already has its shell, Proganochelys doesn't teach us much about shell evolution (Odontochelys helped a bit with that though!). It does, however, demonstrate how turtles lost their teeth very on in their evolutionary development. and it also has the large ear opening that is also found in modern turtles.
One big difference between Proganochelys and modern turtles is the retractability of the head. Our ancient friend simply could not do such a thing. But! They did have small spines on the neck to protect themselves with. Another cool difference? A spiny, clubbed tail!
