Ancient American Lion Tooth Discovered on Dried Up Mississippi River Bank

The fossilized tooth of an ancient American Lion has been discovered on the drying banks of the Mississippi river. The animal hasn't been seen on American soil since the last Ice Age and finds of this nature are extremely rare.

Wiley Prewitt, of Oxford, Mississippi, made the discovery while exploring a recently exposed sandbar near Rosedale, approximately 140 miles northwest of Jackson.

The Mississippi River is the second-longest river in the U.S., stretching 2,350 miles between Minnesota and the Gulf of Mexico. Drought and heat waves over the summer months have caused it, like many others, to see a record decline in water levels.

Land that had been hidden beneath the currents for centuries has now been exposed for the first time. All sorts of historical oddities have been unearthed from the baking banks, including shipwrecks, civil war relics, and now ancient fossils.

"I could tell from the teeth right away that it was a fragment of a carnivore's jaw but I dared not hope it was from an American lion," Prewitt told McClathy News.

The American lion was the same species as the African lions we see today, but it had formed a different subspecies, Panthero leo atrox, Kate Lyons, a paleoecologist at the University of Nebraska, told Newsweek. "The main difference between them and modern day lions is that the American lion was much larger," she said. "Estimates range from half again as big to twice as big as the African lion.

"Because the American lion is just a different subspecies, but the same species as the African lion, it would have looked like a larger version of the African lion. However, we don't know whether or not it had a mane like African lions as preservation of things like skin or hair are very rare in the fossil record."

The American lion is thought to have come to North America around 340,000 years ago. It was last seen on American soil 13,000 years ago, during the last Ice Age.

"Prior to that time, North America had many species of large bodied mammals including multiple species of elephants, bison, llamas, giant ground sloths, saber-tooth cats, similar cats, giant camels, and the American lion," Lyons said. "The evidence for why all these species went extinct points strongly toward humans."

Prewitt's discovery was formally identified by experts at the Mississippi Fossil and Artifact Symposium and Exhibition event at the end of October. It is one of only four known fossils of its kind in Mississippi and was a great surprise to the event's organizers.

"I have had very important artifacts and fossils come into my outreach programs and events, but nothing as significant as the newly discovered American lion fossil," event organizer Anna Reginelli told McClathy News.

Prewitt hasn't yet revealed his plans for the fossil.
