News About The Primordial Earth 18-JUL-08 en-us Paris (AFP) July 16, 2008 - Ninety-three million years ago, Earth was a reshuffled jigsaw of continents, a hothouse where the average temperature was nearly twice that of today.]]> ]]> Moffett Field (SPX) Jul 15, 2008 - The oldest rocks so far identified on Earth are one-half billion years younger than the planet itself, so geologists have relied on certain crystals as micro-messengers from ancient times. Called zircons (for their major constituent, zirconium) these crystals "are the kind of mineral that a geologist loves," says Stephen Mojzsis, an associate professor of geological sciences at the University of Colorado at Boulder.]]> Gainesville, FL (SPX) Jul 09, 2008 - Even in geology, it's not often a date gets revised by 500 million years. But University of Florida geologists say they have found strong evidence that a half-dozen major basins in India were formed a billion or more years ago, making them at least 500 million years older than commonly thought.]]> Santa Barbara CA (SPX) Jul 09, 2008 - Diversity among the ancestors of such marine creatures as clams, sand dollars and lobsters showed only a modest rise beginning 144 million years ago with no clear trend afterwards, according to an international team of researchers. This contradicts previous work showing dramatic increases beginning 248 million years ago and may shed light on future diversity.]]> ]]> New Haven, CT (SPX) Jul 09, 2008 - The traces of organic material found in fossil feathers are remnants of pigments that once gave birds their color, according to Yale scientists whose paper in Biology Letters opens up the potential to depict the original coloration of fossilized birds and their ancestors, the dinosaurs.]]> Madison WI (SPX) Jul 01, 2008 - If you are curious about Earth's periodic mass extinction events such as the sudden demise of the dinosaurs 65 million years ago, you might consider crashing asteroids and sky-darkening super volcanoes as culprits.]]> Canberra, Australia (SPX) Jun 20, 2008 - A team of scientists may have solved the riddle of why plants that work with bacteria to convert atmospheric nitrogen gas into an essential biological nutrient (ammonia) tend to prevail in the world's tropical regions rather than higher latitudes. 19 June 2008]]> ]]> Madison WI (SPX) Jun 19, 2008 - A new analysis of ancient minerals called zircons suggests that a harsh climate may have scoured and possibly even destroyed the surface of the Earth's earliest continents.]]> Madison WI (SPX) Jun 17, 2008 - If you are curious about Earth's periodic mass extinction events such as the sudden demise of the dinosaurs 65 million years ago, you might consider crashing asteroids and sky-darkening super volcanoes as culprits.]]> Paris (AFP) May 28, 2008 - Melting of methane ice unleashed runaway global warming some 635 million years ago, according to a study released Wednesday that has implications for today's climate-change crisis.]]> ]]> ]]> Moffett Field CA (SPX) May 19, 2008 - Asteroid and comet impacts on Earth can cause catastrophic extinction events. They can also bring life back, new research shows. Many scientists believe that a massive rock from space came crashing down 65 million years ago at the end of the Cretaceous Period.]]> Cardiff, Scotland (SPX) May 05, 2008 - The sun's movement through the Milky Way regularly sends comets hurtling into the inner solar system - coinciding with mass life extinctions on earth, a new study claims. Scientists at the Cardiff Centre for Astrobiology built a computer model of our solar system's movement and found that it "bounces" up and down through the plane of the galaxy.]]> Tallahassee FL (SPX) May 02, 2008 - Working with colleagues from NASA, a Florida State University researcher has published a paper that calls into question three decades of conventional wisdom regarding some of the physical processes that helped shape the Earth as we know it today.]]> Advertise in Terra Daily and reach thousands of industry, government and science readers the world over.
