“…The upper La Meseta Formation of Seymour Island, Antarctica is dated as latest Priabonian (late Eocene) on the basis of a wide variety of fossils, including palynomorphs (Mitchell, 1989). Elsewhere, the La Meseta Formation appears to be restricted in age to the eaely Eocene (Ypresian), but upper units run to the end of theEocene on Seymour Island (Reguero et al, 2013). Hence, the Priabonian record of Llanocetus serves as the minimum constraint for the crown cetacean divergence (33.9 Ma ± 0.0 Myr = 33.9 Ma).…”

Calibrations published in the Fossil Calibration Series are accessioned into the Fossil Calibration Database (www.fossilcalibrations.org). The Database is a dynamic tool for finding up-to-date calibrations, and calibration data will be updated and annotated as interpretations change. In contrast, the Fossil Calibration papers are a permanent published record of the information on which the calibrations were originally based. Please refer to the Database for the latest data.

“…47.8 Ma. The Cucullaea I Allomember of the La Meseta Formation has been considered Ypresian (Montes et al 2013), early Eocene, based on Strontium isotopes stratigraphy (Ivany et al 2008) as well as mammal biostratigraphy (Reguero et al 2013). The age of the Ypresian-Lutetian boundary tabulated in GTS 2016 (Ogg et al, 2016) can therefore be used as a conservative minimum constraint.…”
