Hipockets Posted April 19, 2020 Share Posted April 19, 2020 I have an Exogyra costata from the Peedee Form.(Maastrichtian) in North Carolina that has an oddity embedded in the right valve. It is not a shell or barnacle attached to the surface, and is almost perfectly round ,unlike any boring clams I have seen. I have picked ( dental probe) around the oddity to confirm it has depth and is not a surface attachment. It appears it was hollow as it is now filled with hard sediment. It has been suggested this may be an example of bioimmuration of some sort. Anyone have any ideas ? Thanks. Link to comment Share on other sites More sharing options...
