Pleistocene Marker GOM: On the charts I published for the Gulf of Mexico (Styzen 1996, Styzen and Jolley 2008) I have a marker (NP 1.65 in the Shell US nomanclature) based on the extinction of (what I identify as) this species. It is the first downhole occurence of a nice vase shaped Scyphosphaera. From the looks of things The age dates assigned to this part of the section on the 2008 chart (available in Time Scale Creator Pro) are a little off. The event falls between the extinctions of Helicosphaera sellii (see my remarks on that too) and that of \large"Gephyrocapsa (which is an event I've never been able to get to work very well). That would put it between 1.34 and 1.46 ma on the Gradstein, Ogg and Smith timescale. If you look at my comment under small Gephyrocapsa you will see that there is also an acme event for that group in this same interval. The event based on S. pulcherrima is the older of the two, very close to the level of the extinction of H. sellii. """
