Shome S., Bardhan S. The Genus Umiaites Spath, 1931 (Ammonoidea) from the Tithonian (Late Jurassic) of Kutch, Western India // Palaeontologia Electronica. 2008. Vol.12, Issue 1. 2A. 10p.
Recently collected specimens of Umiaites from the latest Jurassic of Kutch, have facilitated a better understanding of this endemic genus. Two previously described species, Umiaites rajnathi and U. Minor, appear to be conspecific, and the former name is retained. An attempt has been made to characterize the sexual dimorphism between Proniceras and Umiaites, the latter being the macroconch.
