Galahadosuchus jonesi was a small early crocodylomorph that lived during the late Triassic of what is now southwest England, around 215 million years ago.
About 60cm long (~2′), it had a fully upright quadrupedal posture, slender digitigrade limbs, a long tail, and a paired row of interlocking osteoderms running along its back.
Its habitat at the time was part of an archipelago of small tropical islands, in a forested karst environment full of sinkholes and caves. It would have been a fast and agile runner, and like its close relative Terrestrisuchus it was probably a generalist pursuit predator feeding on prey such as invertebrates and smaller reptiles.
