An estimate of the duration of the faunal change at the Cretaceous-Tertiary boundary

A detailed analysis of sedimentation rates in the Upper Cretaceous-Paleocene section of pelagic limestones at Gubbio, Italy, based on the previously reported correlation of Gubbio magnetozones with the calibrated sequence of marine magnetic anomalies, suggests that the faunal overturn in planktonic...
