Prehistoric Lizard
DALLAS - Amateur fossil hunter Van Turner felt certain he had found something important during his search of earth turned up by bulldozers making way for a new subdivision in Dallas County. Sixteen years later, scientists finally confirmed that Turner had discovered the first well preserved early mosasaur found in North America - a prehistoric lizard that lived 92 million years ago that evolved into what some call the "T. Rex of the ocean."

Mosasaurs - Prehistoric Lizard (Hover)
I remember digging for fossils in my back yard and finding out that the bone I found was of a cow and the my back yard had once been part of a farm. Its always exciting to find new things in the dirt, especially ones that can tell us so much about the planets past. I just glad these things don't exist any longer!
Scientists cite evidence that mosasaurs were warm-blooded
Mosasaurs – an extinct group of aquatic reptiles that thrived during the Late Cretaceous period – possibly were “endotherms,” or warm-blooded creatures. Mosasurs were large aquatic reptiles that went extinct at the end of the Cretaceous period, about 66 million years ago. Ref. Source 7i.
