Reconstruction of Antarctic palaeoclimates using angiosperm wood anatomy
Fossil angiosperm wood is abundant within Cretaceous and Tertiary sediments on the Antarctic Peninsula. The wood, which represents the trunks and branches of large forest trees that once grew on an emergent volcanic arc, is exquisitely preserved by petrifaction with calcite and silica. Microscopic a...
