Odontochelys, a transitional turtle - The Panda's Thumb:
So, what we have here is a long-legged, toothed reptile with an elongate body, and it also has a plastron like a turtle, and hints in the bony structure of the spine of the carapace-to-be. It also fits perfectly with the embryology: modern turtles form the plastron first, and the carapace second. This is a beautiful transitional form. I’d love to have some swimming in the streams near me. And here’s a reconstruction of what they would have looked like, way back in the Triassic [220 million years ago].

We just got Rickrolled by a Thanksgiving Day Parade.
