These fossil Gryphaea oysters are part of a collection of glacial erratics from Mid-Suffolk given to GeoSuffolk earlier this month. We are sorting them -some will go to a Museum and others will star on some of GeoSuffolk's outreach stands this year. These Gryphaea are 9-10 cm across and have been brought by the ice to Suffolk from Jurassic clays which stretch from the Fenland to Yorkshire.

The Ipswich Society has put a blue plaque for Elizabeth Knipe Cobbold on the stable block in Holywells Park in Ipswich. This Georgian scientist lived here and collected fossil molluscs from the Red Crag on her estate (now Holywells and Landseer Parks). She sent specimens to James Sowerby in London and he published them between 1814 and 1824 in the Mineral Conchology, the first comprehensive publication on British fossils. For more information see Suffolk Naturalists' Society Transactions 2020.
This historic site was monitored by GeoSuffolk for Natural England last week. It was here that two distinctive beds of shelly crag sand were recognised, to which the names Coralline Crag and Red Crag were gven in 1837. The cliff is on private ground and protected as an SSSI, but inspection of the shore at low tide reveals pieces of fossil shell and phosphate nodules - reminders of this site's history.
