Night watchman at the American Museum of Natural History in New York shines his light on a T. rex while making rounds.
T. Rex, "tyrant lizard king," was one of the largest-ever meat eating land animals. The bi-pedal giant grew to some 40 feet (12 meters) and weighed up to 7 US tons (6.5 metric tons) and small two-fingered hands that were actually surprisingly strong.
