Material examined

INDIA • 4 specs; yellowish limestone west of Haripar , Aquitanian, lower Miocene, Kharinadi Formation; 23° 21′12″ N, 68°49′13″ E; Sonar leg.; GIS/B 0461 to 0464 • 6 specs; yellow limestones of the Waghot in Waior-Charopadi stream cliff section and Lakdi Nadi cliff section; Burdigalian, lower Miocene, Chhasra Formation; 23°22′25″ N, 68°58′35″ E; Sonar leg; GIS/B 0465 to 0470 .

Description

Colony unilaminar encrusting. Autozooids subtrigonal to subrectangular, indistinct zooidal boundaries ( Fig. 5A ). Gymnocyst indistinguishable; cryptocyst narrow, thickly calcified, descending into opesia. Opesia subrectangular to subtriangular in shape, elongate, occupying almost entire frontal area. Distal zooidal margins broad, subrectangular ( Fig. 5B–C ). Avicularia small, interzooecial, oval with acute rostrum, randomly placed at corners between autozooids, without crossbar ( Fig. 5C–D ). Ovicells not observed.
