In May 2000, thousands of reporters and spectators jammed into Chicago’s Field Museum of Natural History. They were there for the first public viewing of Sue.
She was the biggest and most complete Tyrannosaurus rex skeleton ever dug up. Her 67-million-year-old fossil told a dramatic story. Part of another T. rex’s tooth was stuck in one of “her” ribs. Actually, nobody knows if Sue is male or female. Also, one of Sue’s legs was broken. This kind of find is a very big deal for paleontologists. Those are scientists who study fossils of prehistoric animals and plants. But even simple fossils tell exciting stories, if you know how to read them.
