Stratigraphy
| Geological group: | Purbeck | Formation: | Lulworth | Member: | Worbarrow Tout |
| Local section: | Durlston Bay | Local bed: | DB102 | ||
| Local order: | bottom to top | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: bed number K93 (also listed as J. 81-84) after Austen (1852); from the Feather Bed Marl level (DB102), not the Feather Bed; also called the "Middle Purbecks". Some dispute as to exact bed within the sequence, but Berriasian age is correct.
