Ancient And Modern Tiny Marine Algae Provide Climate Change Clues
2013-02-04 10:21:39

National Oceanography Centre, Southampton (UK) Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow. Coccolithophores, a type of plankton, are not only widespread in the modern ocean but they are also prolific in the fossil record because their tiny calcium carbonate shells are...

Of all the famous fossil localities in the world – Mongolia´s Flaming Cliffs, Tanzania´s Olduvai Gorge, Wyoming´s Green River, Germany´s Solnhöfn Quarry – perhaps none is as widely celebrated as British Columbia´s Burgess Shale. High in the Canadian Rockies, the Burgess Shale contains some of the oldest and most exquisitely detailed fossils of early life on Earth. Visiting the Burgess Shale requires some preparation – you must hire a...

Martinson-Nicholls new Sof-Tred, Sof-Tyle, Comfort-Eze & Airug® Disposable Surgical Mats are ergonomically designed to reduce back, leg, foot and ankle fatigue. Unlike post applied topical agents, the antimicrobial agent used for these mats is incorporated directly into the foam compound during manufacturing ensuring that it won't wear off. Cleveland, Ohio (PRWEB) December 31, 2012 Martinson-Nicholls announces its new Anti-fatigue, Antimicrobial Healthcare Matting that provide...

Paleontological Enigma Solved Thanks To Scrappy Grave Digger
2012-11-20 12:39:41

Michael Harper for redOrbit.com — Your Universe Online There´s a popular cartoon geared towards adults which tells the story of a hapless young man who accidentally stumbles into a cryogenic capsule just moments before the turn of the century. The capsule just so happens to be set for 1,000 years, long enough for a couple of alien and robot uprisings and for the entire world our character knew to be virtually wiped away. The rest of the show is centered on how this 20th century...

Cretaceous Extinction Worsened By Ecosystem Structures
2012-10-30 04:17:18

April Flowers for redOrbit.com - Your Universe Online A mass extinction, wiping out numerous species including the dinosaurs, marked the end of the Cretaceous Period. A new study, published in Proceedings of the National Academy of Sciences (PNAS), reveals that the structure of North American ecosystems made the extinction worse than it might have been. Mexico's Yucatan Peninsula is home to the now-buried Chicxulub impact crater, caused by a mountain-sized asteroid. This impact is...

Ancient Climate Change Made Hippos Smaller
2012-10-26 11:14:29

April Flowers for redOrbit.com - Your Universe Online Have you heard of giant hippopotamuses wandering along the banks of the Elbe in Germany lately? They are not a common sight today, that is for sure, but 1.8 million years ago, hippos were a prominent part of European wildlife along with other megafauna such as woolly mammoths and giant cave bears. A new study by paleontologists, published in the journal Boreas, claims that the changing climate during the Pleistocene may have forced...

What Triggered North American Dinosaur Diversity?
2012-08-04 07:09:39

redOrbit Staff & Wire Reports - Your Universe Online The rise of the Rocky Mountains and the arrival of a seaway that divided North America into three distinct sections may have been the catalyst for the evolution of new species of dinosaurs, claims a new study published in Thursday's edition of the journal PLoS ONE. The study, which was led by Ohio University (OU) postdoctoral researcher Terry Gates, could explain evolutionary and migratory patterns of North American duck-billed...

Mammal Diversity Aided In Survival Over Deep Time
2012-04-24 12:24:49

Lawrence LeBlond for RedOrbit.com In a first of its kind study, researchers from Vanderbilt University found that mammals´ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes. Larisa R. G. DeSantis, Assistant Professor of Earth and Environmental Sciences at Vanderbilt, led researchers in studying how North American mammals adapted to climate change over a 56-million-year...

Caltech researchers say habitat loss and tropical cooling were to blame for mass extinction The second-largest mass extinction in Earth's history coincided with a short but intense ice age during which enormous glaciers grew and sea levels dropped. Although it has long been agreed that the so-called Late Ordovician mass extinction–which occurred about 450 million years ago–was related to climate change, exactly how the climate change produced the extinction has not been known....

The April/May GSA Today science article is now online at www.geosociety.org/gsatoday/. In this issue, Simon Williams and colleagues from the Earthbyte Group of the School of Geosciences at the University of Sydney present GPlates, a powerful new method for analyzing geological and geophysical data sets within the context of tectonic reconstructions. GPlates is part of a new generation of plate reconstruction software that incorporates functionality familiar from GIS software with the added...

Palaeovespa
2014-04-18 16:08:43

Palaeovespa is a genus of wasps that holds seven species, all of which are extinct. Two of the species were discovered in Baltic amber deposits from Europe dating back to the middle Eocene era, while the other five were found in Florissant Formation amber from the Priabonian stage era in Colorado in the United States. This genus, and four of its species, was first described in 1906 by Dr. Theodore Cockerell in the Bulletin of the Museum of Comparative Zoology. Cockerell described all but one...

Australopithecus africanus
2013-11-29 10:55:07

Australopithecus africanus was an early hominid, an australopithecine that lived between roughly 3.03 and 2.04 million years ago in the later Pliocene and early Pleistocene. Au. africanus was of slender build and was thought to have been a direct ancestor of modern humans. Fossil remains signify that Au. africanus was considerably more like modern humans that Au. afarensis, with a more human-like cranium permitting a larger brain and more humanoid facial features. This hominid has only been...

Image Caption: Head of Tenontosaurus, Institut de paléontologie humaine, Paris, France. Credit: Rémih/Wikipedia (CC BY-SA 3.0) Tenontosaurus, meaning “sinew lizard”, is a genus of medium to large sized ornithopod dinosaur. The genus is known from the late Aptian to Albian ages of the middle Cretaceious period sediments of western North America, dating roughly between 115 to 108 million years ago. It was formerly thought to be a ‘hypsilophodont’, but since Hypsilophodontia is no...

Geologic Clock With Events And Periods

The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...

The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...
