Antarctic Was Tropical During The Eocene Epoch

Brett Smith for redOrbit.com - Your Universe Online As the world´s greatest athletes compete for gold, silver, and bronze in London, new scientific evidence suggests that future summer Olympics could be hosted in a more remote location: Antarctica. An international team of climate scientists has discovered 50 million-year-old fossilized pollen in the seabed off the eastern coast of the polar continent, according to their report published this week in the journal Nature. The...

Ancient Turtles Make Love, Embraced Death
2012-06-21 05:21:32

Lee Rannals for redOrbit.com German paleontologists wrote in the Royal Society Journal Biology Letters that they have uncovered the remains of nine turtle pairs that died while having sex 47 million years ago. The scientists wrote in the report that they had determined the ancient turtles died while mating in poisonous waters. "Millions of animals live and die every year and many enter the fossil record through serendipitous circumstances, but there really is no reason to enter the...

Mammal Diversity Aided In Survival Over Deep Time
2012-04-24 12:24:49

Lawrence LeBlond for RedOrbit.com In a first of its kind study, researchers from Vanderbilt University found that mammals´ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes. Larisa R. G. DeSantis, Assistant Professor of Earth and Environmental Sciences at Vanderbilt, led researchers in studying how North American mammals adapted to climate change over a 56-million-year...

A series of global warming events called hyperthermals that occurred more than 50 million years ago had a similar origin to a much larger hyperthermal of the period, the Pelaeocene-Eocene Thermal Maximum (PETM), new research has found. The findings represent a breakthrough in understanding the major “burp” of carbon, equivalent to burning the entire reservoir of fossil fuels on Earth, that occurred during the PETM. “As geologists, it unnerves us that we don´t know...

Climate Change Drove Shrinkage In Ancient Horse
2012-02-24 05:39:51

The ancient sifrhippus, the earliest known horse, lived around 50 million years ago. It was very distinct in its appearance because it was only about the size of a modern day house cat, weighing in around 12 pounds. The horse lived in what is known as the Paleocene-Eocene Thermal Maximum (PETM), a 175,000 year period where the Earth's atmospheric temperature rose by about 10 degrees Fahrenheit, caused by a great release of carbon into the atmosphere and oceans. In response to the...

Mammalian Evolution Mirrors Climate Change
2011-12-27 05:39:51

A recent study by an international group of evolutionary biologists has pointed to six broad yet distinct ℠waves´ of climate-induced mammalian diversity in the last 65 million years of evolution. Researchers say that extended periods of warming and cooling appear to signal the shift from one dominant grouping of mammals to the next. In the online version of the journal The Proceedings of the National Academy of Sciences (PNAS), Professor Christine Janis of Brown University and a...

Image 1 - 50-million-year-old Clam Shells Hint At Future Of El Niño Phenomenon
2011-09-20 04:44:31

  Earth warming will presumably not lead to a permanent El Niño state in the South Pacific Ocean. This is the conclusion drawn by an international team of researchers after it investigated 50-million-year-old clam shells and wood from the Antarctic. The growth rings of these fossils indicate that there was also a climate rhythm over the South Pacific during the last prolonged interglacial phase of the Earth´s history resembling the present-day interplay of El...

From hot pink to traditional French and Lady Gaga's sophisticated designs, manicured nails have become the grammar of fashion. But they are not just pretty "” when nails appeared on all fingers and toes in modern primates about 55 million years ago, they led to the development of critical functions, including finger pads that allow for sensitive touch and the ability to grasp, whether it's a nail polish brush or remover to prepare for the next trend. In a new study co-authored by...

Team of scientists uncovers new information By Judy Holmes, Syracuse University The question seems simple enough: What happens to the Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record. A new study by researchers from Syracuse and Yale universities provides a much clearer picture of the Earth's temperature approximately 50 million years ago when CO2 concentrations were higher than today. The results may...

Researchers have pinpointed the timing of the start of an ancient global warming episode known as the Paleocene-Eocene thermal maximum (PETM). The early part of the Cenozoic era witnessed a series of transit global warming events called hyperthermals.  The most severe of these was the PETM at the Paleocene-Eocene boundary, which took place around 56 million years ago. Over a 20,000-year period, ocean temperatures rose globally by about 41 degrees Fahrenheit.  The team said one...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
