PARIS:
A finger-sized fossil from 308 million years ago, unearthed in the United States, gives tantalising clues to the habits of tiny dinosaur-like creatures that may be the forerunners of reptiles, researchers revealed today.
The new species is a microsaur – small, lizard-like animals that roamed the Earth more than 250 million years ago, well before proper dinosaurs made their appearance.
The find sheds important light on the evolution of different animal groups, including amphibians and reptiles, scientists wrote in the journal Royal Society Open Science.
