Dimorphodon is among the earliest known pterosaurs, dating back from the early Jurassic period around 200 million years ago. The first discovery in England was made by collector and palaeontologist Mary Anning in Lyme Regis in 1828. Pterosaurs were not just masters of the skies; they were also capable walkers. They folded up their flying fingers to keep their wings out of the way while walking on land. These flying reptiles varied greatly in size. Some had wingspans of just a few inches, while others boasted wingspans exceeding over 9 metres.
