Newly identified saber-toothed cat is one of largest in history

An artist’s depiction of Machairodus lahayishupup eating Hemiauchenia, a camel relative. The image is part of a mural of the Rattlesnake Formation of central Oregon, where fossils of the newly identified species have been found. The mural is exhibited at John Day Fossil Beds National Monument, part of the National Park Service.

IMNH specimens helped to identify a giant saber-toothed cat that lived in North America between 5 million and 9 million years ago, weighing up to 900 pounds and hunting prey that likely weighed 1,000 to 2,000 pounds, scientists reported today in a new study.

These Prehistoric Sharks Had Jaws Shaped Like Circular Saws and Sawtoothed Sciss

More than 300 million years ago, Edestus giganteous bit through its fishy prey with a set of thin, blade like jaws with each serrated tooth set in line right behind the last. There’s nothing quite like this fish alive today, and paleontologists have only recently been able to piece together the relevant clues to understand Edestus and other strange shark relatives from the deep past.
