base notes	Eocene/Oligocene boundary is defined at Massignano (central Italy) at the LAD of Hantkenina spp. and calibrated to magnetics, plus dated by ash beds as ca. 33.7 Ma. Base of Rupellian is at Chron C13r.87 (to round to even 33.90, instead of 33.89 of Westerhold 2014). Essentially, the "top of Eocene" is defined by a LAD, rather than a "base of Oligocene" (e.g., using an FAD).				comp notes
