Missouri Cave Is an Ice Age Time Capsule

The bear who left a three-foot-long mark in an Ice Age clay bank was the largest bear species ever to walk the Earth, about six feet tall at the shoulder and weighing more than 2,000 pounds.

The animal left its mark — and it looks fresh today in a Missouri cave that some scientists consider an Ice Age time capsule sealed for thousands of years.
