Material examined

INDIA • 1 spec.; fossiliferous limestone of Lakdi Nadi near Tera Village , Burdigalian, lower Miocene, Chhasra Formation; 23°22′19″ N, 68°58′10″ E; Sonar leg.; Jan.–Feb. 2012; GIS/B 0515 .

Description

Internode cylindrical, slender, straight, or slightly curved.Autozooids diamond shaped, longer than wide, arranged in 5–6 alternating rows, distinctly separated by raised margins ( Fig. 8A ). Orifice semicircular, proximal lip straight, laterally flanked by pair of robust denticles. Frontal cryptocyst depressed, smooth, surrounded by elongate cryptocystal rim converging on both sides, becoming acute proximally or running parallel ( Fig. 8B ). Avicularia not observed. Ovicell endozooidal, placed at distal extremities of maternal zooids.

Remarks

A single internode is available in the material which lacks avicularia and is therefore difficult to assign to a species, so it is left in open nomenclature until better preserved specimens are found.
