Rugose coral.

Tabulates were an exclusively colonial group, and their coral animals were much smaller than those of rugose corals. Tabulate coral colonies formed a variety of shapes, as shown by the figures above.

Seven of these …One of the fossils, partly embedded in rock matrix, was examined using synchrotron X-ray tomography, which is here demonstrated to be a useful tool in palaeontological taxonomic studies.
