Juvenile and Mother Plesiosaur (Image 1)

July 27, 2010
An artist's depiction of how a mother and juvenile plesiosaur probably looked.

The well-preserved fossil skeleton of a juvenile plesiosaur--a marine reptile that swam the waters of the Southern Ocean roughly 70 million years ago--was recovered by an American-Argentine research team in Antarctica. The fossil remains represent one of the most-complete plesiosaur skeletons ever found and is thought to be the best-articulated fossil skeleton ever recovered from Antarctica. The creature would have inhabited Antarctic waters during a period when the Earth and oceans were far warmer than they are today.
