Near views of the previous white coral fossils patterns. 🪨🪸
The only of my found broken up flint pebbles of sponges, with an struckture patterns visible inside, years back.
All others have just grey chert flint in them or fractured. An identification or pics alike of others to compare or suggestions were nice.
