Comparison Pachydendron differs from another phaceloid genus of the same family, Pachysolenia Cuif, in much smaller corallite diameters, and a very simple septal apparatus with bilateral symmetry [details]
Diagnosis Phaceloid coralla with irregularly oriented corallites of small diameters; increase lateral, producing from one to multiple descendant calices; corallites small, cylindrical; septal apparatus composed of 12 septa, symmetry bilateral underlined by elongated one, or two opposite septa; endotheca composed of rare, tabular elements; wall thick made of centripetally growing fibres organized into modules in the form of fascicles provided with axis. [details]
Remark The genus was monographed by Cuif 1975 based on the material preserved in excellent state in aragonite. New findings are from the Lower Norian of the Central Asia, from the Pamirs (Melnikova 2001:37, pl.6, fig.3,4), and from the Alps, from the Dachsteinplateau (Roniewicz 2010: fig.2H-K). [details]
Status classified by Cuif 1975 in the family Pachythecalidae, junior synonym of Zardinophyllidae Montanaro-Gallitelli, 1975 [details]
