A total of one hundred six samples of the Mesozoic succession of the Kala Chitta Range were processed for the palynological analysis, out of which only twenty one samples proved to be productive. Palynoflora recovered from the productive samples comprise thirty one form genera belonging to thirty three form species. Eighteen triletes, two monoletes, eight bisaccates, two acritarchs and one monosaccates constitute eighteen genera. Palynoflora is less diverse exhibiting little compositional change. Lundbladispora willmotti and L. microconata are age diagnostic for the Upper Triassic Kingriali Formation. Aequitriradites triangulates is typical of the Upper Jurassic- Lower Cretaceous Chichali Formation. Palynoflora are comparatively more abundant in the Lower Cretaceous Lumshiwal Formation containing Succinctisporites grandior, Gordodinium alberti, Leptodineum eumorphum, Foveosporites subtriangularis, Densoisporites nejberji, Enzonalasporites vigens, Minutosaccus crenulatus, Ovalipollis ovalis, Podocarpites ellipticus and Aequitriradites triangulatus. The Upper Cretaceous Kawagarh Formation contains Ptrospermella australiensis of Companian age. The present contribution is the first comprehensive study of its kind from the study area.
