Palynology and micropaleontology of the cretaceous of the james ross basin, antarctica. Review of current knowledge
This paper presents a review of the palynomorph, foraminiferal and calcareous nannofossil record from the Cretaceous sedimentary outcrops of the Gustav and Marambio Groups in the James Ross Basin, Antarctic Peninsula. Fossiliferous localities are described for the James Ross, Vega, Humps, Cockburn,...

Furthermore, previous discoveries of some calcareous nannofossil markers in the basin, have allowed the improvement of the correlations for the lower Campanian and upper Maastrichtian sediments of the Marambio Group. This comprehensive review suggests that palynological and micropaleontological studies in the James Ross Basin are still insufficient to reconstruct the characteristics of the microbiota of this Cretaceous marine basin.

This paper presents a review of the palynomorph, foraminiferal and calcareous nannofossil record from the Cretaceous sedimentary outcrops of the Gustav and Marambio Groups in the James Ross Basin, Antarctic Peninsula.
