Comments
One of the commonest Mississippian corals in the British Isles, France, Belgium, Germany and Russia. Not known from Asia, Africa, Australia or the Americas.
Frequently found as an erratic on many parts of the British Isles coast.
The simplest and narrowest Siphonodendron species (2.5 - 3.8mm), easy to identify as it has no dissepiments.
Central columella present in most corallites, with dome shaped or conical tabulae.
Usually sixteen major septa. (14-18 possible)
Minor septa may be present.
This specimen shows all these features very clearly, partly because the voids have been filled with transparent calcite.
