OSU Scientists Help Identify Largest Saber-Toothed Cat Known to History

In a new study scientist describe newly discovered saber tooth tiger—it lived in North America between 5-9 million years ago. It weighed up to 900lbs and hunted pretty that weighed anywhere from 1,000 to 2,000lbs!

Researchers completed a detailed comparison of seven previously unclassified fossil samples with previously classified fossils and bone samples from all over the world to help them define the new species.

Their findings looked at the elbow portion of the humerus and teeth. This suggested a larger saber-toothed cat whose very large forearms enabled them to pacify their prey.

The new saber-toothed cat scientists identified probably weighed an average of 600lbs (up to 900lbs in the largest cases, theoretically) and could take down prey possibly as large as ten times its own weight. This makes it one of the largest know cats in history that could take down bison-sized prey.



OSU Researchers Discover New Fossil Sea Creature

At the Ohio State University scientists have found a new creature that is about 500 million years old. It is an echinoderm, making it related to your modern day sea urchins, sea stars, sea cucumbers etc. This fossil is special in that it demonstrates evolution by echinoderms that parallel important ecological changes that took place in marine sediments.

The full discovery took about 30 years and the results were published in the Bulletin of Geosciences. The work provides some insight into how the creatures made the evolutionary leap. The leap saw the echinoderms switch from living to sediment grains held to together by algae to being able to live attached to hard or shell like surfaces the way their modern decedents do.

This new sea critter got named Totiglobus spencencis and lived in the Cambrian Period (about 507 million years ago, the Earth being about 4.5 billion years old). The fossil itself was found in the shale of Spence Gulch, eastern Idaho, by a family of fossil hunters in 1992.
