Pantydraco
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 (Wales). It is based on a partial juvenile skeleton once thought to belong to "Thecodontosaurus". Only one valid species of "Pantydraco" is recognised: P. caducus. Description. "Pantydraco" was of moderate build. The creature had a long tail that tapered towards the end and was broad at the hip joint. It had a pointed head  with a strong jaw. The forelimbs of the dinosaur were developed for grasping while the hindlimbs were adapted for supporting the creature's body weight. The center of mass lies near the pelvic bone, meaning the creature was bipedal. The forelimbs were shorter than the hindlimbs. The hands had three movable digits while the fourth digit was embedded. It had well-developed claws. The juvenile fossils’ estimated height is from about . Adults are believed to have been about long. The estimated weight for an average adult of this species of dinosaurs is about . Thus, the creature was fairly gracile. The  teeth were well developed. Discovery and naming. In 2003, Adam Yates named the new species "Thecodontosaurus caducus" for BMNH P 24, a skull, a partial jawbone, and vertebrae of the cervix, an incomplete right pelvic bone, and partial forelimbs of an immature sauropodomorph that had been discovered in 1952 by Kermack and Robinson. This material had been known in the scientific literature since 1983, 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. The genus was named after the Pant-y-ffynnon quarry where it was discovered. Pantydraco" takes its name from the "pant" of Pant-y-ffynnon quarry, meaning valley of the spring, and "draco" (a dragon or mythical dragon-like creature in Latin). This is because the quarry is located near Cowbridge in the Vale of Glamorgan, in Southern Wales, at the base of a mountain between two rivers. As 'y' means '(of) the' in Welsh, the genus name is somewhat grammatically incorrect. The species epithet, "caducus", means "fallen" in Latin, referring to the assumption that it fell  into a fissure fill (quarry) and died there. Paleobiology. "Pantydraco" is considered to have most probably been omnivorous, being at the transition from carnivory to herbivory in the sauropodomorph lineage. It is probable that "Pantydraco" would have walked bipedally. Paleoecology. The Pant-y-ffynnon region was a characteristic wetland during the Triassic. The area consists of alluvial silts deposited by the rivers and sand and limestone. The climate ranges from arid to semi-humid.
