Cuif, 1975:174

classified by Cuif 1975 in the family Pachythecalidae, junior synonym of the family Zardinophyllidae Montanaro-Gallitelli, 1975

Type Species

Pachysolenia cylindrica Cuif, 1975: 174, text-figs. 8, 9, pl. 14: 4, 5; Monotypy Cuif, 1975: 174

Type Specimen: Holotype; MNHN ; Not Traced; Dry Preserved

Type Locality: Alakir Cay (Taurus Mts), Anatolia, Turkey. Stikinoceras kerri zone, Early Norian, Late Triassic

The type material is preserved in aragonite.



Phaceloid of irregular corallite arrangement; corallites cylindrical with tube-like calices distally lacking septa; increase lateral with an early isolation of descentant calice; septa subequal in thckness; septal apparatus radial-bilateral built of septa of three size orders distributed irregularly in the sextants; endotheca built of rare tabuloid elements; wall thick, named pachytheca, made of regular modules in the form of centered bundles of fibers growing centripetally.


Morphological characteristics and detailed description of the microstructure of all skeletal elements were presented in Cuif 1975 with drawings and photos of excellently preserved materials.


From Pachydendron, the other phaceloid genus in the family, Pachysolenia differs in septal apparatus composed of numerous, long, uniformly thin septa, and its subradial symmetry of adult corallites.


This genus is known exclusively from the Lower Norian of the Tethys: in addition to Anatolia, other Lower Norian occurrences of the species are documented from the Pamirs by Melnikowa 2001:36,pl.6,fig.2 and pl.7,fig.2 (and earlier publications), and from the Alps, Dachsteinplateau, by Roniewicz et al. 2007:pl.3,fig.1,and Roniewicz 2010:fig.2A-F.


  • Southern Europe; Late Triassic
  • Central Asia; Late Triassic
Early Norian of the South Europe, Central Asia and West Asia (Turkey).
