The fossil of a cat-sized reptile that is believed to have existed during the age of dinosaurs, approximately 240 to 210 million years ago, was discovered in Scotland. Called Scleromochlus taylori, this reptile is believed to be closely related to an extinct group of flying reptiles called pterosaurs. This creature was around 20cms long and had a big head, short neck, long tail, thin legs and slim body. This discovery could help scientists study the evolutionary history of pterosaurs, which were among the first animals to be able to fly.
