By SUE VORENBERG Scientists hope to gain insight into fossil record by studying current size ranges By Sue Vorenberg The New Mexican Some would say it's impossible to draw a picture of something when you can only see 2 percent of it. With that little information, you might just see a little color, or an edge, or a blue chunk of sky in the background. But impossible or not, that's very much like the picture paleontologists have to work with when they try to rebuild the planet's...

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.But a new study, published online yesterday (June 15, 2008) in the journal Nature, suggests that it is the ocean, and in particular the epic ebbs and flows of sea level and sediment over the course of geologic time, that is the primary cause of the world's periodic mass extinctions...

ASTEROIDS The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the planet's crust liquified, rocketed skyward, and formed tiny airborne beads that blanketed the planet, say scientists from the U.S., U.K., Italy, and New Zealand. The beads, known to geologists as carbon cenospheres, cannot be formed through the combustion of plant matter, contradicting a hypothesis that the cenospheres are the charred remains of an Earth on fire. If...

Researchers in Brazil reported their discovery of a new marine crocodile species on Wednesday, showing that the reptiles survived the mass extinction of dinosaurs 65 million years ago.In the report published in the Proceedings of Royal Society B research journal, paleontologists said they found the new dyrosaurid crocdylomorph in the Poty Quarry, a limestone quarry located close to Recife in northeastern Brazil. Researchers suggested that the Guarinisuchus munizi survived the...

Scientists reported on Thursday that they believe a series of volcanic eruptions in modern day India may have been the cause of mass extinctions of species including dinosaurs over the last 545 million years. The eruptions, which formed "flood basalts," hurled large amounts of sulfur into the atmosphere 65 million years ago during the Cretaeceous period and resulted in damages to the Earth's climate, according to researchers. These eruptions are one of two primary explanations for a series of...

Dinosaur doomsday was wetter than scientists have thought, according to new images of the crater where the space rock that likely killed the dinosaurs landed. Sixty-five million years ago the asteroid struck the coast of the Yucatan Peninsula, and most scientists think this event played a large role in causing the extinction of 70 percent of life on Earth, including non-avian dinosaurs. Geophysicists now have created the most detailed 3-D seismic images yet of the mostly...

AUSTIN, Texas -- The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago.The Chicxulub crater was formed when an asteroid struck on the coast of the Yucatan Peninsula. Most scientists agree the impact played a major role in the "KT Extinction Event" that caused the extinction of most life on Earth, including...

The full recovery of ecological systems, following the most devastating extinction event of all time, took at least 30 million years, according to new research from the University of Bristol. About 250 million years ago, at the end of the Permian, a major extinction event killed over 90 per cent of life on earth, including insects, plants, marine animals, amphibians, and reptiles. Ecosystems were destroyed worldwide, communities were restructured and organisms were left struggling to...
