Paleocene

[′pāl·ē·ə‚sēn]
(geology)
The oldest of the seven geological epochs of the Cenozoic Era, spanning 65 million to 55 million years ago. Comprising the Tertiary and Quaternary periods in modern usage, it is also the oldest of the five epochs constituting the Tertiary Period. It represents an interval of geological time (and rocks deposited during that time) extending from the termination of the Cretaceous Period of the Mesozoic Era to the dawn of the Eocene Epoch.

In the North Pacific the Leg 86 data confirmed a large reduction in aeolian grain size found to occur once before at the Paleocene/Eocene boundary, suggesting that atmospheric circulation in the early Eocene was much more sluggish than in the late Paleocene. Samples from that same cruise were later used to demonstrate that this grain-size change was one of several significant paleoclimatic changes that occur at the Paleocene/Eocene boundary.
