T-Rex Sue Unearthed: Most Complete Dinosaur Found
Sue Hendrickson spotted protruding T. rex bones after her truck tire deflated on August 12, 1990, leading to the discovery of the most complete Tyrannosaurus ever found. This specimen preserved eighty percent of its skeleton, including a massive skull with intact teeth, because rushing water and mud buried it immediately after death. The find revolutionized paleontology by providing an unprecedented look at T. rex anatomy that previous fragmented fossils could never offer.
