UF researcher describes new 5-million-year-old saber-toothed cat from Florida
Date:3/14/2013

GAINESVILLE, Fla. --- A University of Florida researcher has described a new genus and species of extinct saber-toothed cat from Polk County, Fla., based on additional fossil acquisitions of the animal over the last 25 years.

The 5-million-year-old fossils belong to the same lineage as the famous Smilodon fatalis from the La Brea Tar Pits in Los Angeles, a large, carnivorous apex predator with elongated upper canine teeth. Previous research suggested the group of saber-toothed cats known as Smilodontini originated in the Old World and then migrated to North America, but the age of the new species indicates the group likely originated in North America. The study appeared online in the journal PLOS One Wednesday.

"Smilodon first shows up on the fossil record around 2.5 million years ago, but there haven't been a lot of good intermediate forms for understanding where it came from," said study co-author Richard Hulbert Jr., vertebrate paleontology collections manager at the Florida Museum of Natural History on the UF campus. "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. 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 helped uncover fossils of the new genus and species, Rhizosmilodon fiteae, from a phosphate mine during excavations in 1990. The species was named after Barbara Fite of Lutz, Fla., who in 2011 donated one of the critical specimens used for the new description and allowed UF scientists to make casts of two other partial jaws in her collection.

The donation was a major contribution to the research because the remarkably well-preserved lower jaw contains almost pristine examples of all three chewing teeth
