Rhinos are extraordinary Pleistocene survivors - natives of the Britain in both warm & cold phases. 🦏
Here's a recent find (molar, lower jaw) from Norfolk river gravels which GSN members are researching. Could be Coelodonta antiquitatis (cold) or Stephanorhinus hemitoechus (warm). 🌍🗻🪨

East Anglia's mediaeval ship's ballast originated in Cornwall, Scotland, Scandinavia, northern England, the Baltic etc - leapfrogging from ship to shore, shore to ship & back again, over hundreds of years. Their diversity makes a great teaching resource for schools. @discoverdunwich.bsky.social
A large cobble of Anorthosite identified at Dunwich @pavementgeology.bsky.social. Likely to be extremely ancient, formed as scum on the surface of primordial Earth. Later an asteroid smashed into the molten mass, tore off a gobbet of magma which formed the Moon and its Anorthosite crust. ⛰️🌍 #geology
