TqB Posted April 6, 2019 Share Posted April 6, 2019 I agree, it's part of a rugose coral colony from the lower Carboniferous, a species of Siphonodendron, maybe Siphonodendron scoticum. The growth form of this species and a few others is interesting, with corallites often joined in chains for a while before separating. 1 Tarquin Link to comment Share on other sites More sharing options...
