Ancient ocean-floor sediment shows asteroid sizes

Countless asteroids have struck Earth during its multi-billion-year history, leaving few clues to their size because they vaporize on impact and leave no crater or fall into the ocean.

Asteroid that killed dinosaurs downsized

The asteroid that wiped out the dinosaurs may not have been the whopper scientists thought. An analysis of the chemical remains of the asteroid that can be found in sediment under the sea today shows the rock was about 2 1/2 miles wide, according to Francois Paquay, a geology graduate student at the University of Hawaii at Manoa. That's significantly smaller than the estimates of up to 12 miles wide that past researchers had suggested was the size of the dinosaur-killer, according to the research published Friday in the journal Science.

Seawater holds clues to ancient asteroid impacts

Asteroids that strike Earth have cosmic origins, but clues to the size of ancient impactors now have come from a decidedly Earth-bound source: the chemistry of ancient seawater.

Killer asteroid not as huge as believed?

An analysis of the chemical remains of the asteroid that can still be found in sediments under the sea today shows the rock was about four kilometres wide, according to Francois Paquay, a geology professor at the University of Hawaii. That's less than half the 9.6-kilometre-wide space boulder that past researchers have suggested was the dinosaur-killer, according to the research published Friday in the journal Science. The dinosaurs, which ruled Earth for 160 million years, went extinct at the end of the Cretaceous period about 65 million years ago. The killer asteroid theory was bolstered two decades ago, when scientists found in rocks dating from the Cretaceous period a band of iridium, a metal rare on Earth but common in meteorites. The later discovery of the 177-kilometre-wide Chicxulub crater off Mexico's Yucatan peninsula seemingly

Molybdenum crucial to Earths biological flourish

Scientists from around the world have reconstructed changes in Earth’s ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. They have discovered that a deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth for nearly 2 billion years.

Reason For Almost Two Billion Year Delay In Animal Evolution On Earth Discovered

Scientists from around the world have reconstructed changes in Earth's ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. They have discovered that a deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth for nearly 2 billion years.

Lack of Molybdenum May Have Delayed Life on Earth

esocid writes "Scientists from around the world have reconstructed changes in Earth's ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. They have discovered that a deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth for nearly 2 billion years. Bacteria cannot fix nitrogen efficiently when they are deprived of molybdenum. And if bacteria can't fix nitrogen fast enough, then eukaryotes — a kind of organism that includes plants, pachyderms and people — are in trouble because eukaryotes cannot fix nitrogen themselves at all. Ariel Anbar, a co-author of the research of Arizona State University, stated that "eukaryotes depend on bacteria having an easy enough time fixing nitrogen that there's enough to go
