Odontochelys semitestacea, a wonderful new discovery from the Late Triassic of China (published November 2008). It is to date the oldest known turtle and differs from all others by being protected by only the bottom part of the shell (the plastron) and in having teeth in both the upper and lower jaws. It measured about 30-40 cm in length and was probably lived in shallow marine water.
Yep, it got me interested in the origin of turtles! Fascinating... Another one of the recent discoveries I'd like to do is Eileanchelys but there isn't much pictures I could find about it.
I'm asking because I mustn't edit it because it's under CC. ^^
I'll give credits to you.
The guy pointed it out as he noticed how his pet turtles always slid down into their water whenever he passed by.
