†Picrodon herveyi Seeley, 1898

Picrodon is the name given to a genus of archosaur, possibly a sauropodomorph dinosaur,^[1] from the Rhaetian of England which was possibly synonymous with the dubious archosaur Avalonianus.^{[citation needed]} The type, and only species, P. herveyi, was named in 1898.^[2]

In 1894, W. A. Sanford described the fossil remains of what he considered to be two large reptiles discovered near Westbury-on-Severn, Glastonbury (Westbury Formation) by Eev. Sydenham H. A. Hervey and Sanford himself.^[3][2] Harry Govier Seeley described the fossils and named two genera: Avalonia (preoccupied; now Avalonianus) and Picrodon; both are based solely on teeth.^[2]

Only a single tooth, holotype BMNH R2875, belonging to P. herveyi is known, making the remains insufficient to make judgments on its diet or its classification; although it is agreed that Picrodon was an archosaur to some degree.^{[citation needed]}

Sanford (1894)^[3] classified Picrodon as a reptile, while Seeley (1898)^[2] classified Picrodon as a saurian. More modern research however almost certainly places Picrodon within Archosauria;^{[citation needed]} Peter Malcolm Galton (1985) suggested that Picrodon may have been a basal sauropodomorph. Currently, its exact phylogenetic placement within Archosauria remains unknown.^{[citation needed]}
