Palynostratigraphy of the Cretaceous-Paleogene mass-extinction interval of the Southern Hemisphere
(2012) In Dìcéngxué zázhì 36(2). p.153-164- Abstract
- The palynofloral changes around the Cretaceous-Paleogene (K-Pg) mass extinction event reveal the fine
details of vegetation response to a global environmental crisis-in this case an asteroid impact in Mexico 65.5 million
years ago. Due to the extinction of several plant taxa at the K-Pg boundary, palynostratigraphy is a prime tool for localizing
the Cretaceous-Paleogene boundary in non-marine successions. The Southern Hemisphere includes the tropical to
sub-tropical Palmae Province, the high-latitude Nothofagidites/Proteacidites Province, and a transitional zone of mixed
floristic composition. Maastrichtian key-species that go extinct at the Cretaceous-Paleogene boundary within the... (More) - The palynofloral changes around the Cretaceous-Paleogene (K-Pg) mass extinction event reveal the fine
