The Evergreen Formation is a Pliensbachian to Toarcian geologic formation of the Surat Basin in New South Wales and Queensland, eastern Australia. It is Upper Pliensbachian to Toarcian in age.[1][2]
Fossil content[]
The temnospondyl Siderops, and indeterminate plesiosaur fossils are known from the formation, deposited in a lacustrine environment.[3]
