Cyathocoenia

Duncan, 1867, p. 27

Type Species

Cyathocoenia incrustans Duncan 1867, p. 28, pl. 4 fig. 1, 2; Subsequent Designation Wells 1936, p. 105

Type Specimen: Syntype; BRLSI ; Not Traced; Unknown

Type Locality: Lower Liassic of Sutton stone (UK)

Erroneously, Alloiteau considered C. dendroidea as the type species. He was unfortunately followed by Melnikova 1968 and Beauvais 1976 who redescribed the type specimen of this species.

Description

(From the Duncan’s article) Massive cerioid to plocoid corallum with cylindrical corallites. Peritheca granulated and costate. costae non confluent. Distal edge finely dentate, columella absent.

Remarks

Melnikova (1968) observed a large population and dedicated an article to the genus and completed the diagnosis on several points. She noticed the occurrence of a spongy axial formation, more or less well developed ; the extracalicinal gemmation ; the endotheca consisting of tabulae set horizontally or or sloping slightly from the periphery toward the center ; the structure of septa made of simple isolated but close-set trabeculae, sloping at various angles to the wall and thickened by stereoplasm. A comparison with the type material preserved in Bath is still necessary to confirm the validity of the genus.

Distribution

  • Western Europe, Southern Europe, Central Europe, Central Asia; Late Triassic - Early Jurassic
