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.
Here we report on fourteen species of Thalamoporellidae (Bryozoa, Cheilostomatida) from Paleogene–Neogene sediments of the western Kachchh, Gujarat, India. Among these, eleven species are already known from these sediments, whereas two species, namely Thalamoporella badvei n. sp. and T. bhujensis n. sp., are new to science and one is left in open nomenclature. New combinations for two species originally placed in the genus Thalamoporella are also suggested: Dibunostoma transversum n. comb. and Reniporella reniformis n. comb. The genus Reniporella currently placed in the family Steginoporellidae is here re-assigned to Thalamoporellidae mainly based on the position of the opesiules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
