The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling.The study is published in the Jan. 8 issue of the journal Nature.The research casts doubt on the long-held theory that diatoms'...

Life got bigger in two, million-fold leaps, scientists say Extremes are exciting. Does anyone really think dinosaurs would capture our imagination the way they do if they hadn't been so huge? You don't see natural history museums vying for fossil skeletons of prehistoric rodents. It's the Tyrannosaurus rex fossils they salivate and squabble over. And would the Hollywood glitterati cart around those little teacup pups if they weren't so dang tiny and cute? Not likely. Earth's creatures come in...

300 million-year-old discovery in an unlikely setting -- a suburban strip mall While paleontologists may scour remote, exotic places in search of prehistoric specimens, Tufts researchers have found what they believe to be the world's oldest whole-body fossil impression of a flying insect in a wooded field behind a strip mall in North Attleboro, Mass. During a recent exploration as part of his senior project, Richard J. Knecht, a Tufts geology major, and Jake Benner, a paleontologist and...

An analysis of the gut contents from an exceptionally well-preserved juvenile dinosaur fossil suggests that the hadrosaur's last meal included plenty of well-chewed leaves digested into tiny bits. The fossil, Brachylophosaurus canadensis aka "Leonardo," is the second well-substantiated case in which the gut contents of a plant-eating dinosaur have been revealed, said Justin S. Tweet, who was a graduate student at the University of Colorado at Boulder when he studied the fossil with...

By Perkins, Sid New study questions analyses of T. rex remains Three years ago, a team of scientists rocked the paleontology world by reporting the recovery of flexible tissue resembling blood vessels from a 68- million-year-old dinosaur fossil. Now, another group suggests that such pliable material could be something more mundane: a modern-day film of bacterial slime. The techniques used to assess such pliable materials are new to paleontologists, comments Matthew T. Carrano of the...

Massive fossil forests dating back millions of years have been found in Illinois coal mines, a British researcher says. Howard Falcon-Lang told the British Association Science Festival in Liverpool the fossil forests are the largest ever found, the BBC reported Tuesday. He said the fossils cover an area the size of Bristol. The discovery of the first fossil forest in the region along the Illinois, Indiana and Kentucky borders was reported last year. Scientists have since found five more,...

To the editor: In a Wednesday editorial, you responded to my proposal for the creation of a State Paleontologist by asking: "How did this great state survive so long without one?" My answer: Very poorly. Nevada has many priceless paleontological sites, but one of our greatest treasures is the 13,000-acre Upper Las Vegas Wash, one of the most valuable paleontological resources in our nation - perhaps the world. In early 1960, the National Academy of Sciences funded an excavation of only...

By Molly Collins dupageneighbor@@dailyherald.com As this winter drags on, it is hard to picture the Chicago area without any snow, but 300 million years ago that was the case. Illinois actually used to be a wetland located near the equator. If you want to travel back in time to discover more about our warmer past, the Earth Science Club of Northern Illinois is holding its Gem-Mineral-Fossil Show from 10 a.m. to 5 p.m. Saturday and from 10 a.m. to 4 p.m. Sunday in the "K" Commons...

Most of us think fossils are fascinating evidence of life in the past, eons before the first person appeared. People are usually captivated by the large fossils - dinosaurs, mammals and sharks - but only a few ever look at the microfossils. Dinoflagellates, calcareous nanofossils, diatoms, pollen and numerous other microscopic plants and animals are present in the Earth's layers, or strata. In fact, each stratum has its own unique assemblage of fossils. If you learn what fossils are in each...

Musicians and scientists share their passion for fossils in a new TV series When it comes to firing the British public with enthusiasm for old rocks, few people could be better qualified than Dr Hermione Cockburn. The presenter of Fossil Detectives, a new series created by the Open Unversity and the BBC Natural History unit, Cockburn is an earth scientist and Open University tutor, who left full-time academia five years ago to pursue a career in science television. She's been seen in What...

Atrypa
2014-01-12 00:00:00

Atrypa (lampshell) is an extinct genus of brachiopod from the Late Ordovician stage (444 million years ago) to the Carboniferous stage (318 mya). It occurs abundantly as fossils in marine rocks. Fossils have been found on all continents except Antarctica. This animal has distinctive concentric growth lines and is unusual in that in some Devonian beds there are numerous remains of the pedicle (foot) valve, but very few of the brachial (upper) valve -- scientists speculate that strong ocean...

Seitaad, derived from a Navajo legend of a san monster with the same name -- "Seit'aad," is a genus of prosauropod dinosaur from the Early Jurassic Period. The type species, S. ruessi, was described in 2010 based on fossils recovered from the Navajo Sandstone Formation in southern Utah. It is known from a nearly complete fossil that appears to have been entombed by the collapse of a sand dune about 185 million years ago. Based on the fossil, the dinosaur would have been 10 to 15 feet long...
