Skull of one-ton ground sloth found in Kansas
ELLIS COUNTY (KSNT) – The unearthing of a partial skull of a 10-foot-tall ground sloth has prompted a review of the history of the species in Kansas. The paper, published by the Kansas Academy of Science on May 26, claims a mostly intact braincase of Megalonyx jeffersonii, also known as Jefferson's ground sloth, was discovered near Hays in Ellis County. The discovery helps flesh out the distribution of the species during the late Pleistocene. The skull is estimated to be between 12,000-21,000 years old due to its discovery in a significant geological formation in Kansas.

Jefferson originally thought the fossils belonged to a giant cat based on the large claws he found, according to the Illinois State Museum. The Illinois State Museum lists Megalonyx jeffersonii as being between 8-10 feet tall and weighing between 2,200-2,425 pounds. The animal was large and heavily built with large, blunt teeth. The animal's hip bones indicate it could stand on its hind legs which it probably used to strip leaves from trees with its large claws. Megalonyx jeffersonii has a long geological history in Kansas, with records from the late Miocene to the late Pleistocene, according to the paper. The location of Megalonyx jeffersonii in Kansas was associated with river drainages, indicating a reliance on forests within the grassland habitat of the Great Plains. Planned road closures for Emporia Unbound Gravel races As of this new publishing, the Megalonyx jeffersonii has been found in the following Kansas counties: Ellis County – 2025. Jewell County – 1995. Sedgewick County – 1985. Wyandotte County – 1979. Republic County – 1975. Wallace County – 1968. Johnson County – 1967. Meade County – 1938. McPherson County – 1892.

10-foot-tall sloths with ‘large' teeth roamed modern-day Kansas. Now bones found
At the end of the Pleistocene Epoch, 2.6 million to 11,700 years ago, a ground sloth that stood 8 to 10 feet tall went extinct. Now, bones belonging to one have been found in Kansas. A partial skull of the extinct sloth, known as Megalonyx jeffersonii, was found in Ellis County on the Great Plains, according to a study published May 26 in the peer-reviewed journal Transactions of the Kansas Academy of Science. The partial skull was made up mostly of braincase, and it provided a 'better understanding of the distribution of this species in Kansas,' the study said. The ground sloth was 'a large, heavily built animal' with 'a large skull with blunt snout, massive jaw, well-developed chewing muscles, and large, blunt, peg-like teeth,' according to the Illinois State Museum. Unlike modern-day sloths that typically stay in trees, this sloth spent most of its time on the ground, walking on its flat feet and at times standing on its hind legs, the Illinois State Museum reported. They had 'very large claws on their forelimbs' and were 'covered with thick hair,' the museum said. The age of the partial skull was not able to be determined, but because of its presence in the Peoria Loess sediment deposit, it's believed to be from the late Wisconsian between 21,000 and 12,000 years before present. The research team included H. Gregory McDonald, Laura E. Wilson and Melissa Macias Ellis County is about a 170-mile drive northwest from Wichita.
