Arnie Miller, University of Cincinnati professor of paleontology in the McMicken College of Arts & Sciences, and co-author Michael Foote of the University of Chicago publish their research in the Nov. 20 issue of Science with their paper, "Epicontinental Seas Versus Open-Ocean Settings: The Kinetics of Mass Extinction and Origination." http://www.physorg.com/news177873594.html Space & Earth Thu, 19 Nov 2009 17:23:28 EST news177873594 Spanish researchers have studied the fossil record of hadrosaurs, the so-called 'duck-billed' dinosaurs, in the Iberian Peninsula for the purpose of determining that they were the last of their kind to inhabit the European continent before disappearing during the K/T extinction event that occurred 65.5 million years ago. Most notable among these fossils is the discovery of a new hadrosaur, the Arenysaurus ardevoli, found in Huesca, Spain. http://www.physorg.com/news176637618.html Other Sciences Thu, 05 Nov 2009 10:02:14 EST news176637618 (PhysOrg.com) -- Paleontologists from the University of California, Berkeley, and the Museum of the Rockies have wiped out two species of dome-headed dinosaur, one of them named three years ago - with great fanfare - after Hogwarts, the school attended by Harry Potter. http://www.physorg.com/news176132721.html Other Sciences Fri, 30 Oct 2009 14:46:07 EST news176132721 A husband and wife team of American paleontologists has discovered a new species of dinosaur that lived 112 million years ago during the early Cretaceous of central Montana. http://www.physorg.com/news176119692.html Other Sciences Fri, 30 Oct 2009 11:08:52 EST news176119692 (PhysOrg.com) -- Research under way at the New York State Museum indicates that a huge mastodon tusk, recently excavated by Museum scientists in Orange County, may be the largest tusk ever found in New York State. http://www.physorg.com/news175534654.html Other Sciences Fri, 23 Oct 2009 16:38:38 EST news175534654 Imagine the gruesome sound of bones snapping as a thirsty, 30-ton dinosaur tramples a heap of fresh carcasses on his way to a rapidly shrinking lake. http://www.physorg.com/news174717016.html Other Sciences Wed, 14 Oct 2009 05:30:53 EST news174717016 Pittsburgh, Pennsylvania, USA…An international team of paleontologists has discovered a new species of mammal that lived 123 million years ago in what is now the Liaoning Province in northeastern China. The newly discovered animal, Maotherium asiaticus, comes from famous fossil-rich beds of the Yixian Formation. This new remarkably well preserved fossil, as reported in the October 9 issue of the prestigious journal Science, offers an important insight into how the mammalian middle ear evolved. The discoveries of such exquisite dinosaur-age mammals from China provide developmental biologists and paleontologists with evidence of how developmental mechanisms have impacted the morphological (body-structure) evolution of the earliest mammals and sheds light on how complex structures can arise in evolution because of changes in developmental pathways. http://www.physorg.com/news174230741.html Other Sciences Thu, 08 Oct 2009 14:27:44 EST news174230741 (PhysOrg.com) -- You don't have to be a paleontologist to suppose that way back when dinosaurs roamed the Earth chances were good meat eaters would dined on one of their own. Short of a time-machine trip back 70 million years, however, supposing dinosaur cannibalism and proving it are two different stories. http://www.physorg.com/news173982689.html Other Sciences Mon, 05 Oct 2009 17:31:56 EST news173982689 Now, just a few weeks after tiny, early Raptorex kriegsteini was unveiled, a new wrench has been thrown into the family tree of the tyrannosaurs. The new Alioramus altai -a horned, long-snouted, gracile cousin of Tyrannosaurus rex -shared the same environment with larger, predatory relatives. A paper published this week in the Proceedings of the National Academy of Sciences describes this exceptionally well-preserved fossil, shedding light on a previously poorly understood genus of tyrannosaurs and describing a new suite of adaptations for meat eating. http://www.physorg.com/news173974522.html Other Sciences Mon, 05 Oct 2009 15:15:49 EST news173974522 (PhysOrg.com) -- A huge flesh-eating eagle that became extinct in New Zealand only 500 years ago was an efficient hunter that could attack prey 10 times its size, UNSW research has found, lending credibility to a Maori legend about a giant man-eating bird. http://www.physorg.com/news172851408.html Other Sciences Tue, 22 Sep 2009 15:20:48 EST news172851408 (AP) -- Sophisticated computer scans of fossils have helped solve a mystery over the nature of a giant, ancient raptor known as the Haast's eagle which became extinct about 500 years ago, researchers said Friday. http://www.physorg.com/news171900306.html Other Sciences Fri, 11 Sep 2009 15:05:56 EST news171900306 A new University of Florida study could help resolve a long-standing debate in shark paleontology: From which line of species did the modern great white shark evolve? http://www.physorg.com/news156097789.html Other Sciences Thu, 12 Mar 2009 17:33:24 EST news156097789 How did the dinosaur Triceratops use its three horns? A new study published in the open-access, peer reviewed journal PLoS ONE and led by Andrew Farke, curator at the Raymond M. Alf Museum of Paleontology, located on the campus of The Webb Schools, shows that the headgear was not just for looks. Battle scars on the skulls of Triceratops preserve rare evidence of Cretaceous-era combat. http://www.physorg.com/news152370590.html Other Sciences Wed, 28 Jan 2009 13:10:23 EST news152370590 (PhysOrg.com) -- 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. http://www.physorg.com/news150642726.html Biology Thu, 08 Jan 2009 13:12:06 EST news150642726
