Remains identified as those of a woolly mammoth (Mammuthus primigenius) dated at 12,200 ± 55 14C yr B.P. were recovered while excavating in a complex sequence of glaciomarine sediments in Scarborough, Maine, USA. The mammoth was found in the top meter of a fossiliferous unit of mud and sand laminites. These sediments were deposited during a marine regressive phase following the transgression that accompanied northward retreat of the margin of the Laurentide ice sheet. A Portlandia arctica valve from the underlying transgressive unit provides a minimum age of 14,820 ± 105 14C yr B.P. for local deglaciation. The mammoth, an adult female, died in midwinter with no evidence of human involvement. Tusk growth rates and oxygen-isotope variation over the last few years of life record low seasonality. The mammoth was transported to the site as a partial carcass by the late-glacial proto-Saco River. It sank in a near-shore setting, was subjected to additional disarticulation and scattering of elements, and was finally buried in sediments reworked by the shallowing sea.

Terrestrial palynomorphs from the glaciomarine Pagodroma Group provide the first stratigraphically-constrained record of Cenozoic terrestrial vegetation for the northern Prince Charles Mountains, East Antarctica. In general, contemporaneous spores and pollen are extremely sparse, but palynological assemblages of the late middle–late Miocene Fisher Bench Formation and Battye Glacier Formation have relatively more abundant Cenozoic spores and pollen compared with those of the Oligocene Mount Johnston Formation and the Pliocene–early Pleistocene Bardin Bluffs Formation. Spore-pollen assemblages from the Battye Glacier Formation and the Fisher Bench Formation are dominated by Chenopodipollis, with a few other accessory angiosperm and podocarp pollen, pteridophyte and bryophyte spores, and algal cysts, reflecting a low diversity herb-tundra vegetation and a climate similar to the present-day cool to cold sub-Antarctic regions. Reworked Permian–Triassic miospores in Amery oasis (unofficial name) sediments probably indicate local provenance from the Amery Group but Jurassic–Cretaceous and possible early Cenozoic miospores reflect an unknown source.
