Mid-Miocene cooling and the extinction of tundra in continental Antarctica

TL;DR: The discovery of exceptionally well preserved fossils of lacustrine and terrestrial organisms from the McMurdo Dry Valleys sector of the Transantarctic Mountains are reported, providing novel constraints for the timing and amplitude of middle-Miocene cooling in Antarctica and revealing the ecological legacy of this global climate transition.
Journal ArticleDOI

Indication of global deforestation at the Cretaceous-Tertiary boundary by New Zealand fern spike.

TL;DR: Recovery of New Zealand plant communities followed a pattern consistent with major climatic perturbations occurring after an impact winter that was possibly preceded by global wildfires.
Journal ArticleDOI

Palynomorphs from a sediment core reveal a sudden remarkably warm Antarctica during the middle Miocene

TL;DR: An exceptional triple palynological signal (unusually high abundance of marine, freshwater, and terrestrial palynomorphs) recovered from a core collected during the 2007 ANDRILL (Antarctic geologic drilling program) campaign in the Ross Sea, Antarctica, provides constraints for the Middle Miocene Climatic Optimum as discussed by the authors.
