The Birdrong Sandstone is a Lower Cretaceous (Hauterivian to Barremian)[1] 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.[2]
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.[3] 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.[4]
