Abstract
From the San Gregorio Formation (Upper Oligocene-Lower Miocene), Baja California Sur, Mexico, 105.4 meter-deep borehole “B4” was analyzed. Among the continental palynomorphs, four Tubulifloridites taxa, whose botanic affinity is Asteraceae family (Astereae, Eupatorieae and Heliantheae tribes), were recovered and described. The four Tubulifloridites types were classified into three groups according to morphological measures, using k-means cluster analysis. Scanning electron microscope and light photomicrographs were taken. Descriptions complement the contributions made by other authors to this genus, pertaining to the Baja California peninsula during the Paleogene and Neogene and contribute to the geological history of the family.
