On February 7th Suffolk Coast and Heaths AONB volunteers helped GeoSuffolk investigate the junction between the Coralline Crag and the Red Crag at Sutton Knoll. Eight willing helpers dug out a section of the Red Crag beach which sits against the Coralline Crag which forms the higher part of the Knoll. The sedimentology of this 'boulder bed' is complex and the area has been opened up for further investigation. Our Pliocene 'beachcombing' produced a variety of fossil molluscs, including Nucella incrassata, Glycimeris, Natica, Colus and Mytilus.
We found several Neptunea contraria - the photo shows four adorning our Red Crag sandcastle. Caroline Markham
GeoSuffolk's latest production has been published online by the Suffolk Naturalists' Society. Thomas T Paterson (1909-1994) spent some time at the University of Cambridge researching local Early Palaeolithic sites. That at Barnham in Suffolk was published in 1937 and the other Breckland sites were demonstrated at the British Association's 1938 meeting at Cambridge. His thesis has rested in the University Library since 1942 and Professor Richard West has 'rescued' (with comments) the Suffolk geology part of it.
