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.
