(Newser) – A fossil that had been sitting in a museum has been identified by scientists as that of a previously unknown species of crocodile—which is believed to have lived 100 million years ago, the AP reports. Analysis of the six-inch-long skull fossil, which a scientist stumbled upon in 2006, led scientists to determine that the croc belonged to a distinct species, now called Khoratosuchus jintasakuli.

The reptile had longer legs than its present-day descendants, researchers have determined. "They were living on land and could run very fast," said one. Despite that, the crocodile's teeth indicate that it fed mainly on fish.
