Some Calloporid (Bryozoa: Cheilostomata) Species from the Cenozoic Sediments of Western Kachchh, Gujarat

Abstract

Seven species of Calloporid (family Calloporidae Norman, 1903) Bryozoa are described from the Cenozoic sediments of the western Kachchh, Gujarat, India. Among these Planicellaria walsariensis, Dionella sp., Pyriporella charopadiensis, P. vadsariensis and Wilbertopora sp. are new and the other species viz; Crassimarginatella blandfordi and Reptoporina chhasraensis are reported for the second time from these sediments. The phylogenetic analysis suggests all the species of Calloporid bryozoans are monophyletic i.e. all of these species have common ancestor.

Newly discovered species of cheilostomatid Bryozoa from the Miocene of western Kachchh, Gujarat, India

“…To do so, our research group has sampled the entire Miocene sequence from Kachchh region. As a result, Sonar & Gaikwad (2013a, 2013b, 2013c and Sonar & Pawar (2016) have identified poricellariid, steginoporellid, calloporid as well as cyclostomatid bryozoans from the Cenozoic rocks exposed along the shelf zone adjoining the Mesozoic sequences of the western Kachchh (Fig. 1) (Sonar et al 2022).…”
