The caput femoris ball of a fossil mammoth femur picked from the Waveney valley gravels today. Almost certainly Mammuthus meridionalis originating in the Crag, a near-shore marine deposit of Plio-Pleistocene age. Picture a dead animal floating out to sea. Hard bits remain, rolled around by tides.
![Close up view of specimen, showing green acicular crystals of sillimanite set in pale matrix of [quartz] and [feldspar] and reddish brown garnet crystals, perhaps almandine. Magnified 40x with f.o.v. circa 5mm.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:7c3wn5rzzurxcu7ufow7revt/bafkreibp2bnn7wniyujkmhlmmaemtqgbtitucnqryzot5h74j37buccgie)
