Cretaceous (Albian to Coniacian) Ostracodes from the subsurface of the Jaisalmer Basin, Rajasthan, India

Résumé

In the Albian to Coniacian subsurface series of Jaisalmer Basin, Rajasthan, India, the distribution of ostracode assemblages is proposed, calibrated using planktonic foraminifera biozones of the global standard stages. Ninety species, 19 named and 71 in open nomenclature, belonging to 45 known genera and one unknown, are indexed; their first and last appearance (or first and last observation)levels, compared with the stage boundaries, are used as biostratigraphical guide markers. The ostracode assemblages enable us to recognize and define the Cenomanian, Turonian and Coniacian stages. Cenomanian-Turonian faunistic communications appear between the Jaisalmer Basin and different countries of the southern Tethyan margins and the eastern and western Atlantic borderlands.
