[1] The type species is Wahlisaurus massarae, and two specimens have been found: the first consisting of a skull and an incomplete skeleton, and the second a single coracoid.

[2] The holotype specimen, LEICT G454.1951.5, was discovered in the Scunthorpe Mudstone, Barrow upon Soar, Nottinghamshire by Percy Faulkes, and it was donated to the New Walk Museum in Leicester when he died in 1951.

Parts of the specimen were then sent on loan to Robert Appleby until he died in 2004, when they were returned back to the Museum.

[4] Wahlisaurus shares features, such as a slender and long snout, with other leptonectids of that time (e.g. Eurhinosaurus, Excalibosaurus, etc.).

[1] LEICT G454.1951.5 was named in honour of William Wahl and Professor Judy Massare, both specialists in mesozoic marine reptiles who mentored Lomax.
