Palaeophyllia

Alloiteau, 1957, p. 108

Type Species

Montlivaltia pocillum Fromentel 1864, pl. 5 fig. 5, 5a; Original Designation

Type Specimen: Lectotype; MNHN M03525; Verified; Dry Preserved

Type Locality: Oxfordian of Champlitte (Haute-Saône) France

Description

Solitary subcylindrical to trochoid attached corallum. No epitheca. Calice very deep. Radial elements are compact, bicuneiform free costo-septa. Weak torsion of septa in the axial region. The distal edge is ornamented by large teeth or rather festoons. Lateral faces show small granules aligned in subvertical rows, not in real carinae. These rows are more numerous than festoons. Endotheca made of vesicular steeply inclined dissepiments, less inclined near the axial zone. Parathecal wall. No synapticules. No columella.

Remarks

The fig. 62 in Alloiteau 1957 is rather imaginative. This author mentioned the absence of the exotheca. It is difficult to understand in a clearly parathecal wall. Known only from Oxfordian of Champlitte

Distribution

  • Western Europe; Late Jurassic
