@rleder Ronny, here are the three images you asked to be posted here. These are all of the same specimen of Solenopora that I cut and polished for the video. You will recall that the un-cut specimen looks a lot like a petrified brain with growing lobes all around making it a puzzle as to how these were attached in life. The photos all have the upper “life” surface at the top. The section was not cut exactly on center and if you didn’t know better you would think this cut was done horizontally through the specimen rather than vertically as all growth appears radial.
