Description of Sue, the T. rex:
Shortly after its discovery, the fossil became the center of an intense
ownership dispute that resulted in a decision to sell Sue at public auction.To ensure that Sue would be preserved for future generations of scientists and visitors, The Field Museum in Chicago purchased Sue for $8.4 million USD. Field Museum preparators spent more than 30,000 hours preparing the more than 250 bones and teeth in Sue’s skeleton and making exact, fully articulated replicas so that people around the world would have the opportunity to view and study Sue.
As the most complete T. rex specimen ever discovered, Sue has
tremendous value for scientists and the general public. Previously, only
a handful of partial T. rex specimens had been found, none more than
60% complete. At 90% complete and exquisitely preserved, Sue is the
most celebrated representative of its species, permitting more detailed
studies of the biology, growth, and behavior of T. rex than had previously been possible.
Description of the traveling exhibit:
The centerpiece of A T. rex Named Sue is a fully articulated cast skeleton of Sue mounted on a stage. Dramatic lighting throws a spectacular shadow of the skeleton against a graphic backdrop. In another element, visitors can get an eye-to-eye look at a separate cast of Sue’s skull that measures 5 feet (1.52 m.) in length, roars, and growls. Both skeleton and skull are surrounded by reading rails that engage visitors with:
•touchable casts of Sue’s arm bone, tail bone, rib,and teeth;
•interactive activities that let visitors interpret anomalies and diagnose pathologies in Sue’s bones;
•interpretive graphics and text that relate the stories of Sue’s history, from discovery to legal battle to display; incorporate actual headlines, news articles, and behind-the-scenes photos; and describe the process of making casts from fossilized bones.
