The subgroup was first described as a formation by Forbes in 1966. Dinosaur remains are among the fossils that have been recovered from the formation.
An opalised plesiosaur specimen of the genus Umoonasaurus has been nicknamed 'Eric' and was described in 1998 by Schroeder. The decapod crab Dioratiopus salebrosus was described in 1980.
Vertebrate paleofauna
Indeterminate theropod remains present in Western Australia.
