T. Rex: Thunder Thighs

 

Scientists have figured out with more accuracy how much the tyrannical lizard, Tyrannosaurus rex, really weighed, suggesting the largest and most complete skeleton, named SUE, weighed a whopping 9 tons. (SUE's skeleton resides at The Field Museum in Chicago.)

 

 A head-on confrontation with this T. rex named SUE would not be pretty. Scientists aren't sure whether the specimen came from a male or female, though they named it after Sue Hendrickson who discovered it.

The largest and most complete skeleton of T. rex, named SUE after its discoverer, sported a large skull, measuring some 3.3 feet (1 m) across at the back and 5 feet (1.5 m) long.
