Elasmophyllia
Achiardi, 1875, p. 149
Elasmophyllia Achiardi, 1875, p. 149 is a junior homonym (unavailable), see Dordonophyllia Alloiteau, 1957, 195 (the replacement taxon).
Type Species
Elasmophyllia gigantea Achiardi, 1875, p. 149; Monotypy Achiardi, 1875, p. 149
Type Specimen: Holotype; ; Not Traced; Unknown
Type Locality: Eocene of Italy (Friul).
Some of the original material of the d'Achiardi collection could be traced at the Paleontological Institute Pisa, Italy.
Classification
Diagnosis
Colonial, dendroid to subphaceloid. Gemmation intracalicinal. Corallites monocentric to tricentric. Costosepta compact, granulated laterally. Columella lamellar. Endothecal dissepiments vesicular. Wall septoparathecal to septothecal.
Description
Dendroid to subphaceloid corallum; costosepta thin, arranged bilaterally in four complete cycles in six systems in juvenile corallites (3–6 mm), increasing to five incomplete or complete cycles in six systems in later adult or budding stages, respectively; up to 12 septa reach corallite centre; septal flanks finely granulated.
Remarks
Recent re-investigation of the d’Achiardi collection housed at the Paleontological Institute of Pisa (Italy) during the summer of 2003 revealed that only one specimen labeled as Elasmophyllia gigantea d’Achiardi could be found. Despite the fact that it was clearly labeled as having been collected from the type locality of the species (Brazzano), it, however, does not correspond to the original figures of Elasmophyllia gigantea (d’Achiardi 1875: pl. 8, figs 4a–d, pl. 9, fig. 1). Moreover, the poor preservation of the specimen does not allow the precise study of fine details of the skeleton. Therefore, the generic and specific diagnoses of Elasmophyllia gigantea d’Achiardi represent descriptions with characteristics taken from the original description of d’Achiardi (1875: 149) and observations of the specimen at hand, which has to be considered a topotype (Baron-Szabo, 2006).
