A great variety of species can be used in establishing biozonation. Graptolites and ammonites are some of the most useful as zone fossils, as they preserve well and often have relatively short biozones. Microfossils, such as dinoflagellates, foraminiferans, or plant pollen are also good candidates because they tend to be present even in very small samples and evolve relatively rapid… WebMagnitude of the carbon isotope excursion at the Paleocene–Eocene thermal maximum The role of plant community change
