What is "avalonianus"

Avalonianus is a name used for fossil teeth from the Late Triassic of England. It was first described in 1898 by Harry Seeley with the name Avalonia, but that name was preoccupied (Walcott, 1889), so Kuhn renamed it in 1961. It was thought to be a prosauropod, but later analysis revealed it was actually a chimera, with the original teeth coming from a non-dinosaurian ornithosuchian (or possibly an early theropod), and later-referred post-cranial prosauropod remains (which were renamed Camelotia).
