Have you ever wondered how a turtle got its shell? You're not the only one. Paleontologists (古生物学者) have long been confused by the question. But a recently found turtle fossil (化石), the oldest on record, may hold the answer. Researchers report in Nature that the fossil shows shells evolved（进化）as an extension of turtles' backbones and ribs (肋骨).

“The discovery opens a new chapter in the study of the origins and early history of these fascinating reptiles (爬行动物),” says paleontologist Robert Reisz of the University of Toronto.

Scientists have been in the dark until now because all turtle fossils previously discovered had complete shells. (The previously oldest known turtle was discovered in Germany. It dated to about 210 million years ago. ) But this 220 million-year-old fossil is an ancestor of the modern turtle at a stage when its shell was still evolving.

The 40-cm-long fossil was discovered in Guizhou province. An international team of paleontologists led by Li Chun of the Chinese Academy of Sciences in Beijing analyzed it. They reported that the bones belonged to a Triassic (三叠纪的) turtle, which they named odontochelys semitestacea（半甲齿龟）, meaning “toothed turtle with a half shell”.

The fossil has a shelled belly（腹部）and a little extra bone on its spine (脊柱). That supports the theory that turtles' shells formed over time as their backbones and ribs grew. Before the discovery, some paleontologists thought shells were formed as hard, bony plates in turtles' skin, such as those in the skin of modern-day crocodiles. The authors say that this turtle species probably lived in water and that their stomach shell kept them safe from predators (捕食者) below while they were swimming.

B. Paleontologists think turtle shells developed from turtles' hard skin.

C. Some species of turtles don't have stomach shells because they live on land
