Gwyneddosaurus is a possibly invalid
ANSP 15072 and it was discovered by Bock's four-year-old son[1] while the paratype is only listed as ?(ASNP coll.). It was not a large animal; the type skeleton was estimated by Bock as 18 centimetres (7.1 in) long,[1] and its thigh bone was only 23 millimeters long (0.91 in).[2]
type specimen of Gwyneddosaurus as a "gastric ejection" (regurgitation) composed of Tanytrachelos bones and possibly scraps of a coelacanth. They noted that this would make Gwyneddosaurus a senior synonym of Tanytrachelos, and recommended conserving the younger but better-represented genus.[5]
