Temporal range: Late Triassic
Galton, Yates, and Kermack, 2007
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.
In 2003, Adam Yates named the new species Thecodontosaurus caducus for a skull and partial skeleton (neck, partial shoulder girdle, and humeri) of a juvenile dinosaur, with additional material known for it. This material had been known in the scientific literature since 1984, and had been used to represent the genus Thecodontosaurus. However, changed understanding of the relationships and characteristics of basal sauropodomorphs (also known as prosauropods) has led Peter Galton, Yates, and D. Kermack to give T. caducus its own genus.
