ABSTRACT

Echinoids echinoderms are a major group of marine invertebrates with a long fossil record. The oldest echinoids originated during the late Ordovician period, estimated to be about 450 million years ago. Three specimens of Rhabdocidaris sp. (fossil echinoid) belonging to the family Cidaridae are reported for the first time from Kirther range, located in Sindh province. A brief note on the specimens at hand is given.
