The Middle Jurassic, Dharang Member of the Habo Formation, Habo Dome, Kutch, India yields rich foraminiferal assemblages comprising 59 species. The assemblages are dominated by the families Vaginulinidae and Nodosariidae. This paper is a systematic account of the 22 species recorded for the first time from this region. The foraminiferal assemblages indicate a Callovian age for the studied sequence. Based on the foraminiferal evidence, the sediments of the Dharang Member at Habo Dome were deposited in open marine conditions in the middle to outer shelf, with a fluctuating shoreline and within a tectonically unstable shelf zone. The Dharang Member foraminiferal assemblages, as well as other Jurassic foraminiferal assemblages of Kutch and Rajasthan, are assigned to the Indo-East African Province of the Anti-Boreal Realm.

The study explored the taxonomic composition of foraminiferal assemblages from cores sampled in the Sil’ga and Yamal–Tyumen’ facies regions—the southern and southwestern West Siberian sedimentary basin. A complete sequence of biostratons was established for the Callovian–Kimmeridgian sediments of the southwestern West Siberian Lowland and was correlated with the units of the General Stratigraphic Scale. A number of biostratons have been revealed for the south of West Siberia. The biofacies analysis of the foraminiferal assemblages revealed that the Yamal–Tyumen’ facies region belonged to a relatively deep marine environment, far away from the Jurassic Sea littoral zone, in the Callovian through the Kimmeridgian and that the Sil’ga facies region was a relatively shallow marine environment in the Oxfordian through the Middle Volgian.
