So far so good, the mass-disappearance of the Cretaceous planktic foraminifers at Brazos River coincides with the base of the event beds in Brazos River, as Schulte wrote. ❋ Unknown (2006)
In contrast, the carbon-13 shift and Ir anomaly both of which coincide with the first appearance of Danian planktic foramifera, nannofossils and dinoflagellates and faunal turnovers from Cretaceous to Paleocene assemblages well above the event deposit reliably mark the KT boundary. ❋ Unknown (2006)

Please note that particle fluxes are displaced by 2 weeks to account for the delay in shell production and settling of the planktic foraminifera. ❋ Unknown (2006)

He has maintained this claim despite the fact that the two foram experts he has consulted have confirmed the presence of late Maastrichtian planktic foraminifera. ❋ Unknown (2006)

The event deposit and sediments above it were deposited in even shallower seas leading to even greater biotic stress, as evident by the sharp increase of benthic species in the benthic/planktic ratio. ❋ Unknown (2006)
This KT clay and Ir anomaly also coincides with the mass extinction in planktic foraminifera and the first appearance of Tertiary species within a few cm above it. ❋ Unknown (2006)

The biological response to the monsoonal activity in the surface water column is preserved as increased abundance of the planktic foraminifer Globigerina bulloides…Advantages of this proxy are (1) its unique association with the summer monsoon (G. bulloides has a subpolar habitat and would be absent in the tropics except for wind-driven upwelling), (2) linear correlation with the surface cooling due to upwelling, apparently unbiased by other influences ❋ Unknown (2005)
