How the turtle got its shell
Chinese  fossil forces palaeontologists forced to rethink turtle origins.
Natasha  Gilbert 

The discovery, in China, of the oldest known turtle fossil has turned  
palaeontologists' understanding of the species' origin and ecology on its head. 
 
The fossil of Odontochelys semitestacea was found in sediments deposited in  
the Nanpanjiang Trough Basin and dates back 220 million years â around 14  
million years older than previous fossils found in Germany. 
The find  suggests that turtles evolved in a marine environment. The oldest 
turtle fossils  previously found are thought to be from land-based animals, 
which led scientists  to conclude that turtles evolved in a terrestrial 
environment.
