New fossil woods from lower cenozoic volcano-sedimentary rocks of the fildes peninsula, King George Island, and the implications for the trans-antarctic peninsula Eocene climatic gradient
Ten embedded fossil logs sampled in situ from the middle Eocene volcano-sedimentary rocks close to Suffield Point in the Fildes Peninsula, King George Island, Antarctica, are assigned to Protopodocarpoxylon araucarioides Schultze-Motel ex Vogellehner, Phyllocladoxylon antarcticum Gothan, Agathoxylon...
