Ammonites, nannofossils and calpionellids have been studied from Chia Gara Formation

at Banik village (Zakho area, Dohuk Governorate, Kurdistan). New

micropalaeontological work at Banik makes it possible for the first time to identify

useful western Tethyan Jurassic /Cretaceous boundary marker species (calpionellids and

nannofossils) and to make precise correlations with the boundary interval in Europe and

elsewhere. Kurdistan at the end of the Jurassic was positioned on the south side of

Tethys, on the opposite side of that ocean from the type sites and regions for the

Tithonian and Berriasian stages.
