Scientists said Wednesday they had tracked down the oldest known lizard, a tiny creature that lived about 240 million years ago when Earth had a single continent and dinosaurs were brand new. Scans of the fossilised skeleton of Megachirella revealed the chameleon-sized reptile was an ancestor of today's lizards and snakes, which belong to a group called squamates, an international team wrote in the science journal Nature. This finding dragged the group back in time by 75 million years, and means that "lizards inhabited the planet since at least 240 million years ago," study co-author Tiago Simoes of the University of Alberta in Canada told AFP.
