Did Lowly Parasites Kill T. Rex?
The famous dinosaur known as Sue the largest, most complete and best preserved T. rex specimen ever found might have been killed by a disease that afflicts birds even today, scientists now suggest. The remains of Sue, a star attraction of the Field Museum in Chicago, possess holes in her jaw that some believed were battle scars, the result of bloody combat with another dinosaur, possibly another T. rex. Now researchers suggest these scars did not result from a clash of titans, but rather from a lowly parasite. The infection in Sue’s throat and mouth may have been so severe that the 42-foot-long (13-meter-long), 7-ton dinosaur starved to death.
