Pantydraco (where "panty-" is short for Pant-y-ffynnon, signifying hollow of the spring/well in Welsh, referring to the quarry at Bonvilston in South Wales where it was found) was a genus of basal sauropodomorph dinosaur from the Late Triassic of the United Kingdom. It is based on a partial juvenile skeleton once thought to belong to Thecodontosaurus. Only one valid species of Pantydraco is recognised: P. caducus.
