The Birdrong Sandstone is a Lower Cretaceous (Hauterivian to Barremian) geologic formation of the Barrow Group in Western Australia. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.

Description

The Birdrong Sandstone has a maximum thickness of 79 metres (259 ft). The formation overlies the Kockatea Shale, Forestier Claystone and Zeepaard Formation and is overlain by the Muderong Shale, Windalia Radiolarite and Tamala Limestone. At its type section at Mardathuna Station, northeast of Carnarvon, the Birdrong Sandstone begins with a fluvial phase of deposition, followed by deltaic and shallow marine facies.
