![]() “We think southwest Iowa during this period was a parkland with patches of trees interspersed with grassy openings, somewhat similar to central Canada today,” said Hill. Hill says it may have been one of the last sabertooths to walk the planet as glaciers receded and temperatures rose. The researchers used radiocarbon dating to determine the cat died at the end of the Ice Age between 13,605 and 13,460 years ago. Their findings are newly published in Quaternary Science Reviews. Hill analyzed the specimen in collaboration with David Easterla, Distinguished University Professor Emeritus of Biology at Northwest Missouri State University. This skull from the East Nishnabotna River is in near perfect condition. “Finds of this animal are widely scattered and usually represented by an isolated tooth or bone. “The skull is a really big deal,” said Hill. The remarkably well-preserved skull found in Page County is even rarer, and its discovery offers clues about the iconic Ice Age species before its extinction roughly 12-13,000 years ago. The chance of finding any fossilized remains from a sabertooth cat is slim, said Matthew Hill, an associate professor of archaeology at Iowa State and expert on animal bones.
