Abstract

This paper presents a microvertebrate assemblage for the first time from the Fatehgarh Formation exposed in district Barmer, western Rajasthan. The vertebrate fauna represented by well preserved isolated bones, teeth and other skeletal materials, is associated stratigraphically with multiple layers of bedded phosphate and a diverse assemblage of marine benthic gastropods. The vertebrate assemblage comprises cf. igdabatis sp., Semionotiformes indet., Lepisosteus indicus.,?Enchodontidae indet., Albuloidei indet. and ?Stephanodussp . Besides, fragmentary pectoral and dorsal spines of Siluriformes indet. are also present.

A Late Cretaceous age is suggested from close faunistic aSfinities of Fatehgarh vertebrates with those from Lameta and inictrappean sequences. A nearshore marine palacoenvironment is reconstructed from close stratigraphic and taphonomic association of microvertebrate assemblage with phosphorite and sand complex.
