Advanced notes

The presence of columella (central support structures) and septa allow identification of this fossil as a colonial rugose specimen. Columella are not present in tabulate corals as these are always colonial, and do not need the extra support.
Solitary rugose corals developed columella as an internal support structure, and it was retained for some colonial forms, such as this one.
