Abstract

The brissid echinoid Schizobrissus insignis (Duncan & Sladen, 1883) is described from the Fulra Limestone (late middle Eocene), in Kachchh, India. Formerly assigned to Peripneustes or to Meoma it is shown that the species possesses a complete subanal fasciole throughout ontogeny, a characteristic feature of Schizobrissus. Eocene species of Schizobrissus and Meoma show several morphological similarities, but diverged during the late Paleogene and early Neogene.
