The partial skeleton came from a juvenile plesiosaur. It was originally referred to "Plesiosaurus" macrocephalus by Charles William Andrews in 1896, which is otherwise known only from the very young type specimen NHMUK PV R1336. NHMUK OR 49202 was collected at Lyme Regis, of Dorset, from the Hettangian to early Sinemurian-aged beds of the Lower Lias Group.
