The formation comprises moderately-sorted, fine to medium
sandstones with angular
quartz-
feldspathic clasts. Conspicuous rounded green grains are probably
glauconite, but
berthierine cannot be dismissed. The matrix is
micritic and
volcanogenic, possibly
bentonitic. The formation was deposited in an
estuarine to mid shelf
environment. Fossils of sharks, turtles, variety of fish and the tropical dolphin
Urkudelphis were recovered from the formation. == Fossil content ==
