Searching for larger fossils in the form of phosphatic nodules or even larger ones in septaria. Phosphatic nodules are distibuted erratically throughout the clay with no defined stratigraphy to help the collector find specimens. They wash out onto the beach and accumulate with stones of the same size or weight. Specific gravity is the clue as to the where to look. Except this rule does not always apply as they can be lodged against larger stones or in gullies. Most nodules will not have a fossil inside. The ones that do are easily identifiable as the black bone or carapace looks like what it is. Larger fossils like nautili, fish and turtles are very rare but can be found if one is very lucky.
Phosphatic nodule right with 'no one at home' euphemism for it being unfossiliferous, the one on the left shows a typical beach found nodule with a Zanthopsis crab encased. Surplus matrix can be pared away with a scalpel or airpen. Do not try to acid prep as the fossil and matrix are the same chemically.
Septaria showing calcite lined chambers with a Baryte rose as commonly found along the section
Nautilus as found on the beach


Fish skull emerging from the clay slip at the top of the beach
Nautilus still encased in calcite. They are usually broken out of the large septaria
Above is the rather worn skull of a fish. it is so badly damaged that it is impossible to identify. compare it with the 'fish washing out of the clay slip above to see the bony detail that has been lost
