Latest Palynology Stories
Researchers from the University of California, Davis have found new evidence discrediting a controversial theory that a cosmic impact caused a thousand-year period of cold that coincided with the extinction of mammoths and other massive creatures.
A new study published in The Journal of Geology provides support for the theory that a cosmic impact event over North America some 13,000 years ago caused a major period of climate change known as the Younger Dryas stadial, or “Big Freeze.”
There has been quite a bit of controversy in the scientific community regarding what might have initiated the Younger Dryas event—including one that has the event caused by a comet impacting the Earth.
University of Illinois Since the invention of the earliest light microscopes, the classification and identification of pollen and spores has been a highly subjective venture for those who use these tiny particles to study vegetation in their field, palynology. However, according to the lead author of the study, Luke Mander, a former postdoctoral researcher in the laboratory of Illinois professor of plant biology Surangi Punyasena, the limitations imposed by these descriptive rather than...
A new study has found that a cataclysmic asteroid or comet impact in the Canadian province of Quebec nearly 13,000 years ago wiped out many of the world’s large mammals.
Ice samples that profile Greenland glaciers have long been used to give climate scientists historical temperature data, but those samples could be misleading.
Analysis of direct climate record shows Antarctic tundra persisted until 12 million years ago.
A new University of Florida study of 45-million-year-old pollen from Pine Island west of Fort Myers has led to a new understanding of the state's geologic history, showing Florida could be 10 million to 15 million years older than previously believed.
Research at the School of Geographical Sciences, Southwest University (SWU) in Chongqing, China-Research, has demonstrated that the record of the Asian Summer Monsoon (ASM) covers the last deglaciation and the early Holocene (from 16.2 to 7.3 ka BP), with an average oxygen isotope resolution of 9 years (issue 53, May 2010 of SCIENCE CHINA Earth Sciences).
A Texas A&M University scientist spends hours at a time peering at slides of pollen samples, comparing them to track down the origins of honey with questionable heritage.
