Fig. 2. Stratigraphic log of part of the Purbeck Group exposed in the northern part of Durlston Bay showing the horizons from which mammal remains have been recovered, and the horizon from which the new specimens described here were obtained. Redrawn from Clements (1993) using the author's "erosional profile" but with additional bed names. Detailed comments on lithologies and palaeontology are contained in the above publication in which all bed numbers bear the prefix DB.
