Lately uncovered sandbars alongside the drought-stricken Mississippi River have caught the eye of fossil hunters, main to 2 distinctive finds from a uncommon ice age species.
Wiley Prewitt was exploring a newly uncovered space on October 26 when he got here throughout a quite massive tooth poking out of the sand. The Oxford, Mississippi, resident would quickly be taught it was a fossilized jawbone from an enormous American lion, a species that has been extinct for roughly 11,000 years.
“I knew instantly simply by the form of the tooth that it was a carnivore fossil, however after all, I didn’t know that it was (an American) lion. Everyone knows about these, however you by no means dream that you simply’re going to search out one,” Prewitt stated. “I simply couldn’t consider it. It was hitting the fossil lottery. ”
The American lion was the most important extinct cat to stay in North America over the past ice age, in accordance with the Nationwide Park Service. Identified by its scientific title, Panthera atrox, which means “fearsome panther” in Latin, the species was 25% bigger than a present-day African lion, standing at 4 toes tall on the shoulders and measuring 5 to eight toes in size. American lions weighed between 500 to 800 kilos on common, though a number of the largest might have topped 1,000 kilos, the park service notes.
Three days after Prewitt’s discover, the Mississippi Fossil and Artifact Symposium & Exhibition hosted an occasion that includes beforehand found American lion fossils. Prewitt took the fossil within the hope of getting specialists establish it, however he didn’t know the way important his discover can be to understanding slightly extra about Mississippi’s previous.
“When (Prewitt) whipped out that anterior portion of a lion jaw, I knew instantly what it was,” stated George Phillips, curator of paleontology on the Mississippi Museum of Pure Science, who was on the occasion. “Who would have thought in 1,000,000 years that one other lion fossil would present up, contemplating that they’re uncommon, at an occasion (in) which the theme was the American lion?”
Whereas the fossil was not a whole jawbone, lots was left to establish the specimen simply, Phillips stated: It had a major hole between the canine and the premolars that would solely belong to the American lion. After observing different fossils from the identical species on the occasion, Phillips stated it was simple to slim down the opposite carnivore potentialities and make sure that he was one other fossil from the lion.
One week after that shocking discovery, a neighborhood wildlife officer pulled a big American lion femur from the river’s sediment, leading to one other fossil from the identical scarce species being added to the museum’s assortment, Phillips informed CNN.
Carnivore fossils are a lot more durable to search out compared with their prey counterparts, in accordance with Phillips. Two American lion bone discoveries inside every week or so is unbelievable, he stated, calling it “simply an extremely uncommon fossil.”
Prewitt plans to donate the fossil he discovered to the museum in Jackson, which might make it the fourth addition to the establishment’s assortment of American lion bones, counting the addition of the newly discovered femur.
“The attention-grabbing factor in regards to the river is that yearly is totally different. When the river comes up, the excessive water exposes various things and covers up different issues. So right here, you might be at all times new websites,” Prewitt stated. “The fossils actually make you ponder deep time, and I believe that, for me, that’s actually a part of the magic of it.”
The primary fossil of the American lion was present in Natchez, Mississippi, in 1836, however paleontologist Joseph Leidy didn’t establish it till almost 20 years later. Leidy discovered that the fossil, a decrease jawbone, belonged to a never-before-discovered species. It was bigger than the extinct European cave lion, the most important recognized member of the cat household on the time. Earlier than then, it was unknown that big lions had roamed North America.
“I believe individuals take higher pleasure in an space after they understand that one thing like this exists — some side of the antiquity of the world the place they stay,” Phillips stated. “Archaeologists attempt to do the identical factor, to indicate that there have been people who have been right here earlier than you. Nicely, there are additionally extinct, weird-looking creatures that have been right here earlier than you.”
