Ostracodes from the Jurassic Beds of Habo Hill, Kachchh, Gujarat, India

Jurassic Foraminifera from the Dharang Member, Habo Formation, Habo Dome, Kutch, India: systematics, age, palaeoecology and palaeobiogeography

“…The Kutch region displays an excellent development of Jurassic rocks ranging in age from Bajocian to Tithonian (Biswas 1993;F€ ursich et al 1994, 2001Krishna et al 2000;Krishna 2005Krishna , 2012Rai & Jain 2012). Although the macrofossils of these rocks have been investigated in considerable detail, there are only a small number of studies on the microfossils including the foraminifera (Bhalla & Abbas 1978;Bhalla & Talib 1991;Pandey & Dave 1993;Khosla et al 1997Khosla et al , 2004Khosla et al , 2005Gaur & Talib 2009;Talib et al 2012aTalib et al , b, 2014. These studies indicate that the microfauna, especially the foraminifera, are abundant and well preserved but are in need of a comprehensive review.…”

Discovery of the first ichthyosaur from the Jurassic of India: Implications for Gondwanan palaeobiogeography

“…The appearance of ammonid genera characteristic of different palaeobiogeographic provinces, such as Tithopeltoceras and Durangites of the Mediterranean Province and Himalayites of the Mediterranean Tethys and Indo-Madagascan Province in the Late Tithonian fauna of Kachchh has been explained in terms of interprovincial migrations facilitated by high sea level [ 104 – 107 ]. Many of the ostracod taxa reported from the Callovian-Oxfordian Chari Formation and lower part of the Kimmeridgian Katrol Formation also demonstrate close affinities to those of Rajasthan (western India), Madagascar, Tanzania and central Saudi Arabia thus favouring faunal exchanges between the western Tethys and the Indo-Madagascan Province as early as in Oxfordian-Kimmeridgian time [ 108 ].…”

Middle to Upper Jurassic sedimentary sequences and marine biota of the early Indian Ocean (Southwest Madagascar): some biostratigraphic, palaeoecologic and palaeobiogeographic conclusions

“…The Callovian taxon Fastigatocythere (Amicytheridea) triangulata (Bate, 1975) has been described from the Middle Callovian of Tanzania, the Upper Callovian of the Majunga Basin and the Callovian of India. Other ostracod species which support the Lower-Middle Callovian age are Fastigatocythere (Batella) falcula (Grekoff, 1963), F. (Habocythere) bicruciata (Grekoff, 1963), Neurocythere whatleyi (Khosla et al, 1997), T. devexa and M. mundula. The succession at the Ranonda section consists of shallow marine sandstones.…”

“…The Callovian ostracod faunas from the Morondava Basin have six species in common with India (Khosla et al, 1997) and indicate therefore intensive faunal exchange between these two regions. This distribution pattern is in accordance with current palaeogeographic models which suggest that Madagascar and India were connected by a shallow marine shelf during Middle and Late Jurassic times (Fig.…”
