- Terrestrial deposits contain fossils ranging from Paleocene leaf imprints to Cretaceous dinosaur remains.
- Initiation of a cold, upwelling current off the west coast of South America dates back to latest Cretaceous to earliest Palaeocene times.
- This trend is evident at a coarse scale in a comparison of the combined rarefaction curves for sites from the uppermost 15 m of the Cretaceous against all Paleocene sites.
The Paleocene epoch lasted from 65 million to 56.5 million years ago. It was a time of sudden diversification among the mammals, probably as a result of the mass extinctions (notably of the dinosaurs) that occurred at the end of the Cretaceous period (see Cretaceous-Tertiary boundary)
late 19th century: from paleo- (relating to prehistoric times) + Greek kainos 'new'.
