Moss Helps Chart The Conquest Of Land By Plants St. Louis MO (SPX) Feb 08, 2010 
Recent work at Washington University in St. Louis sheds light on one of the most important events in earth-history, the conquest of land by plants 480 million years ago.
No would-be colonizer could have survived on dry land without the ability to deal with dehydration, a major threat for organisms accustomed to soaking in water.
Clues to how the first land plants managed to avoid dry ... read moreAdding Color To A Flying Dinosaur 
Washington DC (SPX) Feb 08, 2010Deciphering microscopic clues hidden within fossils, scientists have uncovered the vibrant colors that adorned a feathered dinosaur extinct for 150 million years, a Yale University-led research team reports online in the journal Science. Unlike recently published work from China that inferred the existence of two types of melanin pigments in various species of feathered dinosaurs, the Scie ... more

Carbonate Veins Reveal Chemistry Of Ancient Seawater
Southampton UK (SPX) Feb 08, 2010The chemical composition of our oceans is not constant but has varied significantly over geological time. In a study published this week in Science, researchers describe a novel method for reconstructing past ocean chemistry using calcium carbonate veins that precipitate from seawater-derived fluids in rocks beneath the seafloor. The research was led by scientists from the University of So ... more Novel Studies Of Decomposition Shed New Light On Our Earliest Fossil Ancestry 
Leicester UK (SPX) Feb 04, 2010Decaying corpses are usually the domain of forensic scientists, but palaeontologists have discovered that studying rotting fish sheds new light on our earliest ancestry. The researchers, from the Department of Geology at the University of Leicester, devised a new method for extracting information from 500 million year old fossils -they studied the way fish decompose to gain a clearer pictu ... more New Evidence Links Humans To Megafauna Demise 
Adelaide, Australia (SPX) Feb 02, 2010A new scientific paper co-authored by a University of Adelaide researcher reports strong evidence that humans, not climate change, caused the demise of Australia's megafauna - giant marsupials, huge reptiles and flightless birds - at least 40,000 years ago. In a paper published today in the international journal Science, two Australian scientists claim that improved dating methods show tha ... more New dinosaur fossil could provide clues to evolution 
Washington (AFP) Jan 28, 2010US paleontologists said Thursday they have uncovered a new dinosaur species in China's Gobi Desert that could explain how one dinosaur family came to look like birds. The finding extends by 63 million years the fossil record of the Alvarezsauridae family, a group of bird-like dinosaurs with a large claw on their hands and very short, powerful arms. It was the first evidence that this typ ... more |

Rich Ore Deposits Linked To Ancient Atmosphere
Washington DC (SPX) Nov 27, 2009Much of our planet's mineral wealth was deposited billions of years ago when Earth's chemical cycles were different from today's. Using geochemical clues from rocks nearly 3 billion years old, a group of scientists including Andrey Bekker and Doug Rumble from the Carnegie Institution have made the surprising discovery that the creation of economically important nickel ore deposits was linked to ... more A Hazy View Of Early Earth 
Moffett Field CA (SPX) Oct 19, 2009Haze in the early Earth atmosphere could have played a crucial role in the origin of life. By forming a protective shield, the haze would have safeguarded organic substances from harmful ultraviolet (UV) radiation. "Knowing more about the atmospheric conditions right before life began to develop could give researchers clues to how exactly life developed," says H. Langley DeWitt of the ... more Scientists find flying reptile an odd duck 
Portsmouth, England (UPI) Oct 14, 2009 Fossils of a flying reptile found in China reveal a strangely disjointed creature, British paleontologists say. "It's as if someone said, 'Let's nail these two together and make a sort of chimera, that'll really confuse everybody,'" said Dave Unwin of the University of Leicester in England. This version of pterodactyl appears so strange it conjures up the image of an old second-r ... more Huge dinosaur find in China may include new species: state media
Beijing (AFP) Oct 14, 2009Paleontologists in east China may have discovered the remains of a new species of dinosaur at what is said to be the world's largest group of fossilised dinosaur bones, state media said Wednesday. Scientists in Zhucheng city, Shandong province, have for months been exploring a gully over 500 metres (1,650 feet) long and 26 metres deep that is strewn with thousands of dinosaur bones, the Jilu ... more |
