Tidgy's Dad Posted August 13, 2020 Share Posted August 13, 2020 I think it's the internal mold of a pentamerid brachiopod. 6 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

PaleoOrdo Posted August 14, 2020 Author Share Posted August 14, 2020 Here is a scale picture for one of the last ordovician stone (the other, cambrium, fossile is about 1 cm in diameter and could well be an echinoderm): Link to comment Share on other sites More sharing options...
