Introduction to the “Circum-Arctic Palynological Event Stratigraphy” (CAPE) series of papers

Palynomorphs are one of the few groups fossils that provide biostratigraphic control in marine to nonmarine rocks and can be applied as proxies for paleoenvironmental paleoclimatic interpretations. Their utility is enhanced by their microscopic size, which usually less than 200 micrometres; they thus easily recovered from small rock samples. They occur throughout Phanerozoic therefore invaluable refining Arctic successions Alaska, Canada, Greenland, northern Europe, Russia. The objective Circum-Arctic Palynological Event (CAPE) Stratigraphy series papers integrate data published on palynomorphs delineate palynological events (palynoevents) across Silurian Cenozoic. Once complete, will also used compile a TimeScale Creator datapack updated calibrated an ongoing basis. Palynoevents include taxon originations (first occurrences or FOs) extinctions (last occurrences, LOs) some abundance events. palynoevents correlated with established chronostratigraphic horizons such bases ammonoid zones stages, hence chronostratigraphy independent absolute time scale millions years. In addition palynostratigraphic papers, includes paper detailing paleogeography circum-Arctic regions, including informative maps, well providing perspective Cenozoic shift greenhouse icehouse conditions.
