From Diving to Digging
By the mid-1980's, Sue had also tried her hand at amber mining in the Dominican mountains and became one of the largest amber providers for scientists. It was at this time that she uncovered three perfect 23-million year old butterflies, half of the whole world’s total collection, and became an expert at identifying fossilized insects.
A Swiss paleontologist called Kirby Siber allowed her to join his team of paleontologists. The group began excavating whale fossils at an ancient seabed in Peru, and Sue joined the team for several summers, discovering fossilized dolphins, seals, and sharks.
By this time, paleontology had become her main passion.
The Tyrannosaurus Rex
On August 12, 1990, while examining a cliff-side in South Dakota she discovered an important Tyrannosaurus Rex specimen — the largest, most complete, and best preserved T-Rex ever found. It was such a fantastic discovery that the find would later be named in her honor.
