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.

Out in Breckland today, the 'ghost pond' team @carlsayer.bsky.social @hburningham.bsky.social excavating a backfilled Ice Age doline pit, had to contend with sediments full of smelly burnt wood, barbed wire and mutilated tree trunks, before reaching the sought-after organic-rich sediment layers.

They are hoping to find seeds buried in the mud which might be in a fit state to sprout again.Two people taking sediment cores from the dark-coloured floor of a 'ghost pond' excavation trench about 6 ft / 2 m deep.
