For a long time, debate has taken place regarding the trends and extinction rates associated with the Cretaceous-Paleogene (K-Pg) mass extinction event on land. In this paper, the authors present a review of the late Cretaceous to Paleogene pollen and spore stratigraphy in the Northern Hemisphere Aquilapollenites paleophytogeographic province. The K-Pg extinction event remains easily identifiable in the palynological record with the disappearance of a series of angiospermous taxa, part of the Wodehouseia spinata Assemblage Zone, which are characterized by relatively large size and a complex wall structure. The recovery palynoflora in the Paleocene is represented by assemblages dominated by porate grains, with key species from the Momipites and Caryapollenites genera.
