Description Dendroid corallum. Subcylindrical corallites. Calices infundibuliform, cutting calicular edge. Thin subequal costae locally covered by an epitheca. Extracalicinal increase producing branches with a wide angle of divergence. Radial elements are compact free attenuated or swollen at the inner edge, straight to sinuous costosepta. Distal edge smooth, inner edge often swollen, lateral faces not ornamented, no pali (but some rare mimetic situations for some particular septa). Microstructure unknown. Clear hexameral symmetry. Bilateral symmetry marked in some calices by the eccentricity of the fossa. Endotheca made of dissepiments (a good longitudinal section is missing to know how it is structured), columella absent but a rather well defined fossa, synapticulae absent, wall of unknown nature.

Comparison Thamnocoenia seems to be very close of Goniocora that has a columella. [details]Description Dendroid corallum. Subcylindrical corallites. Calices infundibuliform, cutting calicular edge. Thin subequal costae locally covered by an epitheca. Extracalicinal increase producing branches with a wide angle of divergence. Radial elements are compact free attenuated or swollen at the inner edge, straight to sinuous costosepta. Distal edge smooth, inner edge often swollen, lateral faces not ornamented, no pali (but some rare mimetic situations for some particular septa). Microstructure unknown. Clear hexameral symmetry. Bilateral symmetry marked in some calices by the eccentricity of the fossa. Endotheca made of dissepiments (a good longitudinal section is missing to know how it is structured), columella absent but a rather well defined fossa, synapticulae absent, wall of unknown nature. [details]
Remark One nominal species, and one specimen known. The granulations evoked by Beauvais size in the range of diagenetic calcite crystals that constitute the fossil. There are not taken into account. There is no clear evidence such as auricules to assign Thamnocoenia to Stylinidae. [details]
