Fossil pollen records reveal a late rise of open-habitat ecosystems in Patagonia [PDF]
, 2012 The timing of major turnovers in terrestrial ecosystems of the Cenozoic Era has been largely interpreted from the analysis of the assumed feeding preference of extinct mammals. For example, the expansion of open-habitat ecosystems (grasslands or savannas)
