Australia: The Land Where Time Began

A biography of the Australian continent 

Blina Shale

The Blina Shale is a riverine palaeoenvironment dated to the Early Triassic that Kear et al. suggest was probably an extensive delta system that they believe was brackish-marine spread across the northwestern part of the Canning Basin in Western Australia over a period from the Permian to Early Triassic.  In the Erskine Ranges the Blina Shale is an exposure predominantly comprised of yellow shales and claystones. It is notable for containing bone beds reaching to 3 m thick of vertebrate bones that are thought to have accumulated as the current flow rate decreased in coastal lagoons and backwaters.
