World's oldest lizard lived when Earth had only 1 continent
Scientists have identified the oldest known lizard, a reptile that lived about 240 million years ago when Earth had a single continent geographically and dinosaurs had just emerged. Discovered 20 years ago in Italy, "mother of all lizards" Megachirella was initially misclassified as a lizard relative. The discovery pushed back the origins of lizards by 75 million years, said researchers.
