Class Anthozoa Ehrenberg, 1831

Remarks.—Several observations lead to the conclusion that the fossil under study is a coral: (i), tubes are not preserved in original calcitic microstructure; (ii), even if septa are abortive they exist; (iii), the tubes are branching and provide a phaceloid colonial structure; (iv), tubes are conical rather than cylindrical; (v), walls are compact, not perforated. All these observations discard serpulid, scaphopod and sponge interpretations.
