Ceratothecia carniolica Turnšek, 1972, p. 177/236; Original Designation
Type Specimen: Holotype; SAZU P352; Not Traced; Dry Preserved
Type Locality: Upper Oxfordian- Lower Kimmeridgian, 1 km south of the Frata Hunting lodge in Dolenjsko (Slovenia)
Thin sections exist.
Description
Dendroid-phaceloid corallum with corniform corallites circular in cross section. Radial elements are costosepta with a costal part very short or absent. Septa short, compact, sparsely spaced, laterally occasionally granulated, straight or slightly bent. The symmetry is hexameral but the torsion of septa adds a slight bilateral symmetry. Microstructure of simple small trabeculae arranged in a mid-septal line. The nature of the wall, previously reported as a septoparatheca, is unclear. Tabular endotheca mainly restricted to the lower part of the corallite. No columella, no palus, no synapticule.
Remarks
Errenst 1990 modified the initial diagnose in which the genus was solitary. The emendation was acknowledged in Turnšek 1997.
Distribution
- Southern Europe; Late Jurassic
Upper Oxfordian- Lower Kimmeridgian of Slovenia ; Lower Kimmeridgian of Spain ; Liao and Xia 1994 have also cited this genus from Upper Jurassic of Tibet but their corals are solitary.This page has been in preparation since 07-May-2009 09:54
