A lignite-bearing section at Matanomadh (N23°30′; E68°55′) in Kutch was examined for its foraminiferal assemblage. The section consists of lignite and carbonaceous shale in the lower part and mudstone in the upper part. The mudstone is characterized by a low diversity and moderate abundance of dwarf foraminifera. The presence of Halkyardia minima, Linderina kutchensis and Lockhartia alveolata suggests its correlation with Fulra Limestone exposed in the adjoining regions of Kutch. The smaller benthic foraminifera mainly include the species of Brizalina, Bulimina, Trifarina, Cibicides, Discorbis and Guttulina. The Rectilinear Benthic Foraminifera morphogroup (RBF) constituting up to 60% of the foraminiferal assemblage are characterized by large pores. These are typical characteristics of foraminiferal assemblages from low oxygen environment. The peak abundance of RBF occurs consistently at co-eval levels in several sections of Kutch. It is suggestive of dysoxic conditions in late Middle Eocene, corresponding to planktonic foraminiferal zone P13.
