(Bran Point, showing separation of Bencliff Grit and Osmington Oolite) - 2000
(Trigonia Clavellata Formation, The Red Bed) - 2000
The cliffs at Osmington are well known for their excellent sections of Corallian beds and Kimmeridge Clay. Landslips of the Cretaceous Cenomanian Basement bed are often seen. West of Osmington Mills the upper part of the Corallian and the lower Kimmeridge clay is more frequent and at Black head, a full sequence of Kimmeridge Clay from the basal beds to levels above the White Stone Band can be observed.
East of the slipway from the car park at Osmington Mills, Northe Grit forms the lower cliffs. At the lowest cliff point, a waterfall over the Preston Grit is quite famously landmarked.
Walking East, the Qualicosta Bed forms a ledge west of Bran Point, from here, a fault brings the Middle White Oolite bed against the Pisolite. Still walking East, the Trigonia beds can be seen in the cliffs which dip to beach level.
