The November 3rd edition of the journal Science contains news of the recent discovery of what might be the earliest bipedal reptile. This page from the University of Toronto is an illustrated news release about the discovery. The 290-million-year-old fossil, found in Germany in 1993, looks like an upright lizard approximately 25-30 cm long with forearms and a long tail. The reptile lived before dinosaurs between 295 and 250 million years ago. It was discovered by an international team of researchers, including two paleontologists from the University of Toronto.
