Journal ArticleDOI

TL;DR: It is shown that the climate in lowland settings along the Wilkes Land coast (at a palaeolatitude of about 70° south) supported the growth of highly diverse, near-tropical forests characterized by mesothermal to megathermal floral elements including palms and Bombacoideae.
Journal ArticleDOI
Mid-Miocene cooling and the extinction of tundra in continental Antarctica
A. R. Lewis,David R. Marchant,Allan C. Ashworth,Lars Hedenäs,Sidney R. Hemming,Jesse V. Johnson,Melanie J. Leng,Malka L. Machlus,Angela E. Newton,J. Ian Raine,Jane K. Willenbring,Mark Williams,Alexander P. Wolfe +12 more
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
Sophie Warny,Rosemary A. Askin,M. J. Hannah,Barbara A. R. Mohr,J. Ian Raine,David M. Harwood,Fabio Florindo +6 more
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.
Journal ArticleDOI

TL;DR: In this paper, the vegetation patterns in Australia, Southeast Asia and the Pacific (SEAPAC region) in the mid- Holocene and at the last glacial maximum (LGM) were reconstructed from pollen data using an objective biomization scheme based on plant functional types.
