1583 in grey siltstone lens at base of cliffs on southern side of Camden Head, N.S.W.

loc. 1583 = Camden Head Claystone. In a lens of hard grey siltsone at the base of Camden Head. This is the locality from which Came (1897, 1898) , Voisey (1939) , Pratt (1970) and Retallack (1977) have collected. It is commonly called the Perpendicular Point locality but the original locality descriptions given by these authors indicate that their collections actually came from the base of Camden Head not Perpendicular Point.
