Thecodontosauridae

Lydekker 1890

Thecodontosauridae is a family of basal sauropodomorph dinosaurs that are part of the Bagualosauria, known from fossil remains found exclusively in the Magnesian Conglomerate of Bristol, England, which has been traditionally considered to date back to the Rhaetian stage of the Late Triassic. However, other studies have challenged this and suggested a much older date extending back to the Carnian. Two genera are known: Agrosaurus and Thecodontosaurus; the former is often considered to be the same animal as the latter.
