| Kanjilal S. (2014) Revisiting the proposed ammonite zonation of Jurassic rocks of Gangta Bet, Wagad, eastern Kachchh // Journal of the Palaeontological Society of India. Vol.59. no.1. P.103-107.

The newly proposed biozones by Patel et al. (2012 - see http://ejurassic.ucoz.ru/forum/7-784-1 ) have been based on the so-called characteristic index species, which have been identified incorrectly. The zonation should remain suspended till finding the true index fossils.
