Saber Toothed Cat Fossil Reveals New Genus and Species Of Extinct Predator

RATE THIS! +11
Posted in Science on 16th Mar, 2013 11:20 PM by AlexMuller

The fossil, which is 5 million years old, is related to the well-known carnivorous predator Smilodon fatalis from the La Brea Tar Pits of Los Angeles.

 

The group of saber-toothed cats called Smilodontini was thought to have originated in the Old World and later migrated to North America, but the new species' age suggests the group evolved in North America, researchers reported March 13 in the journal PLOS ONE.

 

Although Smilodon appears in the fossil record about 2.5 million years ago, there weren't many intermediate forms to tell scientists where it originated, according to study co-author Richard Hulbert Jr., vertebrate paleontology collections manager at the Florida Museum of Natural History.

 

"The new species shows that the most famous saber-toothed cat, Smilodon, had a New World origin, and it and its ancestors lived in the southeastern U.S. for at least 5 million years before their extinction about 11,000 years ago," Hulbert said in a statement. "Compared to what we knew about these earlier saber-toothed cats 20 or 30 years ago, we now have a much better understanding of this group."

 

Hulbert and colleagues discovered the fossils of the new cat, Rhizosmilodon fiteae, during the excavation of a phosphate mine in 1990. The species was named for Barbara Fite of Lutz, Fla., who donated a fossil of the species from her collection that had a very well-preserved lower jaw with all three chewing teeth. The name Rhizosmilodon means "root of Smilodon," because researchers believe the creature could be the direct ancestor of Smilodon, which went extinct 11,000 years ago.

 

The researchers did a comparative analysis of saber-toothed cat anatomy to determine its biological grouping. The animal's lower jaw and teeth were smaller than Smilodon's, about the size of a modern Florida panther, the results showed.
