This Day In History: 08/12/1990 - Skeleton of T-Rex Discovered

On August 12, 1990, Susan Hendrickson -- a fossil hunter -- discovered three huge bones protruding out of a cliff near Faith, South Dakota.

Those burned turned out to be part of the largest ever T-Rex skeleton to ever be discovered, a 65 million-year-old specimen which was eventually named Sue.

When Sue's skeleton was found, it was over 90 percent complete, with extremely well-preserved bones.

The Black Hills Institute of Geological research, Hendrickson's employer, paid the land's owner $500 for the right to excavate the skeleton.

Eventually, in May 2000, Sue's skeleton went on display at the Field Museum.

This discovery was huge for the world of discovery and dinosaur bone excavation, marking Sue as a monumental icon in dinosaur history.
