"Largest" ever fossil rodent found:
A rodent as big as a bull once roamed South America,
Dinosaur Mummy Discovered. National Geographic Specials Sunday night December 9, 2007. Look for rebroadcast dates and times. See web pages below.
IIn the book "A Natural History of Time" Mr. Richet sets out to explore humanity's attempts to answer this most perplexing of questions, which acted as a spur and a baffle to human ingenuity for 2,500 years.
Agonized Death Throes Probable Cause Of Open-mouthed, Head-back Pose Of Many Dinosaur Fossils (June 11, 2007) -- Like investigators out of CSI or Cold Case, paleontologists are finding clues to a dinosaur's demise in its peculiar death pose. The peculiar pose of many fossilized dinosaurs, with wide-open mouth, head thrown back and recurved tail, likely results from the agonized death throes typical of brain damage and asphyxiation, according to two paleontologists.
Ancient DNA Traces Woolly Mammoth's Disappearance (June 10, 2007) -- Some ancient-DNA evidence has offered new clues to a very cold case: the disappearance of the last woolly mammoths.
Earth Mantle 'Ocean': 3-D Seismic Model Of Vast Water Reservoir Revealed A seismologist at Washington University in St. Louis has made the first 3-D model of seismic wave damping -- diminishing -- deep in the Earth's mantle and has revealed the existence of an underground water reservoir at least the volume of the Arctic Ocean. It is the first evidence for water existing in the Earth's deep mantle.
BIG, BAD AND FURRY
What's new in the world of dinosaurs? Giant mammals. And we're not talking woolly mammoths or cave bears: those didn't evolve until long after the dinosaurs had gone extinct. We're talking giant mammals that lived alongside the dinosaurs, at a time when textbooks say they should have been tiny, primitive and shrew-like. And that's not the only surprise. Airborne mammals may have existed 100 million years earlier than we thought and taken to the air before birds. Fossil discoveries are painting a very different picture of Mesozoic era.
Who Laid The First Egg? Scientists Closer To Linking Embryos Of Earth's First Animals And Their Adult Form (January 23, 2007) -- A decade ago, geobiologist Shuhai Xiao and his colleagues discovered thousands of 600-million-year-old embryo microfossils in the Doushantuo Formation.
Rare Plant From Dinosaur Age (January 15, 2007) -- A relic plant that once co-existed with dinosaurs has taken up residence in the University of Wisconsin-Madison botany greenhouses. Known as the Wollemi pine, the plant was presumed extinct until a "bushwalker" named David Noble discovered it in an Australian national park in 1994.
Oldest Complex Organic Molecules Found In Ancient Fossils. Ohio State University geologists have isolated complex organic molecules from 350-million-year-old fossil sea creatures -- the oldest such molecules yet found.
Blame for global warming placed firmly on humankind
The most authoritative scientific report on climate change says with 90%
certainty that the burning of fossil fuels and other human activities are
driving climate change.
Ohio State University geologists have found that important rocks from Niagara Gorge -- rock formations that are used to judge the ages of rocks and fossils around North America -- formed five times faster than previously thought.
Evidence Of Gut Parasite Found In Dinosaur. University of Colorado at Boulder researchers have discovered what appears to be the first evidence of parasites in the gut contents of a dinosaur.
Far More Than A Meteor Killed Dinos, Evidence Suggests There's growing evidence that the dinosaurs and most their contemporaries were not wiped out by the famed Chicxulub meteor impact, according to a paleontologist who says multiple meteor impacts, massive volcanism in India and climate changes culminated in the end of the Cretaceous Peroid.
Learning To Live With Oxygen On Early Earth
Washington DC (SPX) Oct 17, 2006
Scientists at the Carnegie Institution and Penn State University have discovered evidence showing that microbes adapted to living with oxygen 2.72 billion years ago, at least 300 million years before the rise of oxygen in the atmosphere. The finding is the first concrete validation of a long-held hypothesis that oxygen was being produced and consumed by that time and that the transition to an oxygenated atmosphere was long term.
Giant Bugs Thrived on High-Oxygen Earth Oct. 11, 2006 ? The enormous dragonflies, millipedes and other insects that lived 300 million years ago grew to such sizes thanks to Earth's rich oxygen supply at the time, according to a new study. Harrison and his team analyzed how modern insects are designed for today?s 21-percent-oxygen air, focusing on the tracheal system ? interconnected tubes that transport oxygen throughout bug bodies. By extension, the researchers envisioned what insects would have looked like millions of years ago when the air was composed of 35 percent oxygen. Their findings help explain the remains of 4-foot-long millipedes, 4-inch cockroaches and dragonflies with 2 1/2-foot wingspans dating to the late Paleozoic period just before dinosaurs came on the scene.

Earth's Wobble Wipes Out Species Oct. 12, 2006 ? Climate change, naturally induced by tiny shifts in Earth's rotational axis and orbit, periodically wipes out species of mammals, a study published on Thursday says. See http://dsc.discovery.com/news/2006/10/12/wobble_pla.html

Possible Evidence Of Cell Division, Differentiation Found In Oldest Known Embryo Fossils A group of 15 scientists from five countries has discovered evidence of cell differentiation in fossil embryos that are more than 550 million years old. They also report what appear to be cells about to divide. The discovery will be reported in the Oct. 13 issue of Science. See http://www.sciencedaily.com/releases/2006/10/061012184639.htm
Little or no sediment has accumulated on a broad patch of ocean bottom in the remote South Pacific, the result of a combination of factors that probably can't be found anywhere else on Earth.
Research Reveals How Continents Can Break Apart. A paper co-authored by CSIRO's Professor Klaus Regenauer-Lieb and published in Nature reveals new information on the strength of continents and how they can split.
Warming 55 Million Years Ago Shifted Ocean Currents Paris (AFP) Jan
An extraordinary burst of global warming that occurred around 55 million years ago dramatically reversed Earth's pattern of ocean currents, a finding that strengthens modern-day concern about climate change, a study says.
drill for climate clues in Antarctic ice. TOKYO (Reuters)
Japanese scientists have gone back in time to study the earth's climate by drilling more than 3 kilometres into Antarctica's ice sheet, a researcher said on Tuesday. Yoshiyuki Fujii said the cores are among the oldest samples yet extracted by scientists and hoped bubbles of gas, such as carbon dioxide, trapped in the core samples will offer clues to past patterns of global climate change.
