ynot Posted March 25, 2019 Share Posted March 25, 2019 Looks like the carapice to Me. I would expect the steinkern to be the same color as the matrix. 2 minutes ago, cck said: As tagged Always a good idea to include that information in the text also.

cck Posted March 25, 2019 Author Share Posted March 25, 2019 Yes sorry- I would have thought so as well, but the texture is odd and the borings gave me pause Link to comment Share on other sites More sharing options...
Rockwood Posted March 25, 2019 Share Posted March 25, 2019 Typically these concretions do preserve the actual body fossils. I think this one was just not a best effort. Link to comment Share on other sites More sharing options...
