We’ve all heard this story: the Late Cretaceous of Asia and North America-about 65 million years ago-was dominated by several large-headed, bipedal predatory dinosaurs like Tyrannosaurus rex and Tarbosaurus that had tiny arms. But a decade of new fossil discoveries that have more than doubled the number of known tyrannosaur species has changed this tale. Older and smaller tyrannosaurs […]

riffin Ammonites Found Mini Oases at Ancient Methane Seeps
August 4th, 2012
riffin Research led by scientists at the American Museum of Natural History shows that ammonites-an extinct type of shelled mollusk that’s closely related to modern-day nautiluses and squids-made homes in the unique environments surrounding methane seeps in the seaway that once covered America’s Great Plains. The findings, published online this week in the journalGeology, provide new […]
Humble bug plugs gap in fossil record
August 4th, 2012
riffin Paris – One day 370 million years ago, a tiny larva came to a sticky end when it plunged into a shrimp-infested swamp and drowned.Unearthed in modern-day Belgium, the humble bug now looks set to plug a giant gap in the fossil record. Named Strudiella devonica, the eight-millimetre invertebrate – while in far from mint condition […]
Oldest species of a marine mollusc discovered
August 2nd, 2012
Riffin An international research team, with Spanish participation, has discovered a new species of mollusc,Polyconites hadriani, in various parts of the Iberian Peninsula. The researchers say this species, which is the oldest in its genus, adapted to the acidification of the oceans that took place while it was in existence. This process could now determine the […]
Geological ‘Pulse’ Causes Cycle of Extinctions Every 60 Million Years, Scientists Report
August 1st, 2012
Riffin A mysterious cycle of booms and busts in marine biodiversity over the past 500 million years could be tied to a periodic uplifting of the world’s continents, scientists report in the March issue of The Journal of Geology. The researchers discovered periodic increases in the amount of the isotope strontium-87 found in marine fossils. The timing […]
TRICERATOPS WAS LAST DINOSAUR STANDING
July 31st, 2012
Riffin A Triceratops may have been the last dinosaur standing, according to a new study that determined a fossil from Montana’s Hell Creek Formation is “the youngest dinosaur known to science.” The Triceratops, described in the latest Royal Society Biology Letters, dates to 65 million years ago, the critical period of time associated with the Cretaceous-Tertiary (K-T) extinction event that […]
Palaeontologists solve mystery of 500 million-year-old squid-like carnivore
July 31st, 2012
riffin A study by researchers at the University of Toronto and the Royal Ontario Museum sheds new light on a previously unclassifiable 500 million-year-old squid-like carnivore known as Nectocaris pteryx. “We think that this extremely rare creature is an early ancestor of squids, octopuses, and other cephalopods”, says Martin Smith of U of T’s Department of Ecology […]
An Earthquake in a Maze: Sumatra Earthquake
July 30th, 2012
riffin The powerful magnitude-8.6 earthquake that shook Sumatra on April 11, 2012, was a seismic standout for many reasons, not the least of which is that it was larger than scientists thought an earthquake of its type — an intraplate strike-slip quake — could ever be. Now, as Caltech researchers report on their findings from the […]
Some dinosaurs declined before asteroid extinction
July 30th, 2012
riffin Tyrannosaurus rex was still making a nice living, paleontologists report, but some other dinosaurs declined in numbers long before the asteroid hit 65.5 million years ago . In the journal Nature Communications, a team led by Stephen Brusatte of the American Museum of Natural History in New York, look at seven major dinosaur sub-groups, ranging from T. […]
Discovery of World’s Largest ‘Dinosaur Eggs’ Hatches Doubt
July 29th, 2012
riffin Scientists from Russia’s Chechen State University claim to have unearthed at least 40 of the world’s largest “dinosaur eggs,” measuring up to 3 ft. (1 m) in diameter and dating back roughly 60 million years. Apparently, while blasting through rocks to build a road in southern Russia’s turbulent Chechnya republic, workers found a cluster of […]
