Panphagia is a genus of sauropodomorph dinosaur described in 2009. It lived 231 million years ago, during the late Ladinian age of the mid Triassic period (according to the ICS; alternately the early Carnian age of the Late Triassic in the system used by the Geological Society of America), in what is now northwestern Argentina. The name Panphagia comes from the Greek words pan, meaning "all", and phagein, meaning "to eat", in reference to its inferred omnivorous diet. Panphagia is one of the earliest known dinosaurs, and is an important find which may mark the transition of diet in early sauropodomorph dinosaurs.

 Fossils of Panphagia were found in late 2006 by the Argentinean paleontologist Ricardo N. Martínez in rocks of the Ischigualasto Formation of Valle Pintado, Ischigualasto Provincial Park, San Juan Province, Argentina. The bones were found at approximately the same level as a 231,4 million year old ash layer, indicating it lived during the early Carnian of the Late Triassic. Panphagia is currently known from holotype PVSJ 874, the disarticulated remains of one partially grown individual of about 1.30 metres (4.3 ft) long. Portions of the skull, vertebrae, pectoral girdle, pelvic girdle, and hindlimb bones have been recovered. The russet-colored fossils were embedded in a greenish sandstone matrix and took several years to prepare and describe.

 Panphagia was described in 2009 by Ricardo N. Martínez and Oscar A. Alcober, both of the Museo de Ciencias Naturales, in San Juan, Argentina. They performed a phylogenetic analysis and found it to be the most basal known sauropodomorph dinosaur: the fossils shared similar features to those of Saturnalia, an early sauropodomorph, including similarities in the ischium, astralagus, and the scapular blade. Yet the fossils also exhibited similar features to those of Eoraptor, an early carnivorous saurischian, including hollow bones, sublanceolate teeth, and overall proportions. Based on analysis and comparison of the Panphagia fossils and those of its closest kin, Martínez and Alcober concluded that the evolution of saurischian dinosaurs likely began with small, cursorial animals similar to Panphagia, and that there is a "general similarity among all of these basal dinosaurs [suggesting] that few structural changes stand" between Panphagia, Eoraptor, and two basal theropods which have yet to be described.

 The type species of Panphagia is P. protos; the specific name, meaning "the first" in Greek, is a reference to its basal position.

 The teeth of Panphagia indicate a possible omnivorous diet, transitional in form between the mostly carnivorous theropods and the herbivorous sauropodomorphs. The teeth in the back of the jaw are shorter than those in the front, are leaf-shaped, and also have more marked serrations.

 Pantydraco — род ящеротазовых динозавров из группы Sauropodomorpha, живших в позднем триасовом периоде (около 228-199 миллионов лет назад), на территории нынешней Европы. Окаменелости были найдены в Англии. Впервые описан палеонтологом Yates и Kermack в 2007 году. Представлен одним видом - Pantydraco caducus.

 Pantydraco (where "panty-" is short for Pant-y-ffynnon, referring to the quarry 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.

 As a basal sauropodomorph, Pantydraco would have been an omnivore, probably mostly bipedal.
