About 12,800 years ago when the Earth was warming and emerging from the last ice age, a dramatic and anomalous event occurred that abruptly reversed climatic conditions back to near-glacial state. According to James Kennett, UC Santa Barbara emeritus professor in earth sciences, this climate switch fundamentally –– and remarkably –– occurred in only one year, heralding the onset of the Younger Dryas cool episode. http://phys.org/news288367533.html Space & Earth Tue, 21 May 2013 15:05:47 EST news288367533 During the late Pleistocene, a remarkably diverse assemblage of large-bodied mammals inhabited the "mammoth steppe," a cold and dry yet productive environment that extended from western Europe through northern Asia and across the Bering land bridge to the Yukon. Of the large predators—wolves, bears, and big cats—only the wolves and bears were able to maintain their ranges well after the end of the last ice age. http://phys.org/news287243844.html Biology Wed, 08 May 2013 14:57:55 EST news287243844 A team of paleontologists in Mexico City say they have recovered the remains of an ancient mammoth, using methods typically employed by archaeologists—a first in Latin America. http://phys.org/news284824318.html Other Sciences Wed, 10 Apr 2013 14:52:09 EST news284824318 The latest study of the microscopic wear patterns on the teeth of the American lions and saber-toothed cats that roamed North America in the late Pleistocene found that they were living well off the fat of the land in the period just before they went extinct. http://phys.org/news275756705.html Other Sciences Wed, 26 Dec 2012 17:00:07 EST news275756705 (Phys.org)—A University of Nevada, Las Vegas research team recently unearthed fossil remains from an extinct wolf species in a wash northwest of Las Vegas, revealing the first evidence that the ice age mammal once lived in Nevada. http://phys.org/news274862391.html Other Sciences Sun, 16 Dec 2012 06:42:42 EST news274862391 A near-complete skeleton of a mammoth which lived between 200,000 and 500,000 years ago has been found near Paris, the French National Institute for Preventive Archaeological Research said Tuesday. http://phys.org/news271418823.html Other Sciences Tue, 06 Nov 2012 10:07:11 EST news271418823 A teenage mammoth who once roamed the Siberian tundra in search of fodder and females might have been killed by an Ice Age man on a summer day tens of thousands of years ago, a Russian scientist said Friday. http://phys.org/news268650124.html Other Sciences Fri, 05 Oct 2012 10:02:10 EST news268650124 In an international cooperative project, archaeologists from the Monrepos Archaeological Research Centre and Museum for the Evolution of Hominin Behaviour are excavating the 35,000 year old site of Breitenbach, close to Zeitz in Saxony-Anhalt. http://phys.org/news267957937.html Other Sciences Thu, 27 Sep 2012 09:45:45 EST news267957937 (Phys.org)—New research findings published in the Proceedings of the National Academy of Sciences (PNAS) are consistent with a controversial theory that an extraterrestrial body – such as a comet – impacted the Earth approximately 12,900 years ago, possibly contributing to the significant climatic and ecological changes that date to that time period. http://phys.org/news267772277.html Space & Earth Tue, 25 Sep 2012 06:13:26 EST news267772277 Scientists have discovered well-preserved frozen woolly mammoth fragments deep in Siberia that may contain living cells, edging a tad closer to the "Jurassic Park" possibility of cloning a prehistoric animal, the mission's organizer said Tuesday. http://phys.org/news266588107.html Other Sciences Tue, 11 Sep 2012 13:15:12 EST news266588107 Workers digging on the underground network in the western city of Duesseldorf have uncovered a 34-kilogramme (76-pound) woolly mammoth tusk over 10,000 years old, city officials said on Tuesday. http://phys.org/news264767661.html Other Sciences Tue, 21 Aug 2012 11:34:26 EST news264767661 Serbian archaeologists have discovered the remains of at least seven mammoths at a dig at an open pit mine, which could turn out to be a mammoth cemetery, lead archaeologist Miomir Korac told AFP Friday. http://phys.org/news260190763.html Other Sciences Fri, 29 Jun 2012 12:50:01 EST news260190763 (AP) — An unusual discovery of mammoth bones on a rural Oskaloosa farm has experts studying prehistoric life excited about scientific discoveries that may lie with the massive beast. http://phys.org/news258222269.html Other Sciences Wed, 06 Jun 2012 17:24:33 EST news258222269 (Phys.org) -- A new University of Florida study that determined the age of skeletal remains provides evidence humans reached the Western Hemisphere during the last ice age and lived alongside giant extinct mammals. http://phys.org/news255278803.html Other Sciences Thu, 03 May 2012 15:47:00 EST news255278803 The world's best-preserved mammoth, buried about 42,000 years ago, will go on display in Hong Kong this week, the organiser of its first exhibition in Asia said Wednesday. http://phys.org/news253365543.html Other Sciences Wed, 11 Apr 2012 12:19:15 EST news253365543 (PhysOrg.com) -- An exceedingly well preserved juvenile mammoth carcass has been found in Siberia near the Arctic Ocean and it shows signs of having been attacked by a cave lion and then partially butchered by humans. Dubbed Yuka by the Mammuthus organization, which is studying the remains, the six foot long creature was believed to have been a year and a half to perhaps three or four years old at the time of its death. http://phys.org/news252834958.html Other Sciences Thu, 05 Apr 2012 08:57:10 EST news252834958 Russian and South Korean scientists have signed a deal on joint research intended to recreate a woolly mammoth, an animal which last walked the earth some 10,000 years ago. http://phys.org/news250831583.html Biology Tue, 13 Mar 2012 04:27:26 EST news250831583 (PhysOrg.com) -- Up till recently, most researchers studying Neanderthals had assumed they were simple wanderers, hiding out in caves when the weather got bad. Now however, the discovery of the underpinnings of a house built by a group of Neanderthals, some 44,000 years ago, turns that thinking on its head. Discovered by a team of French archeologists from the Muséum National d'Histories Naturelle, in an area that had been under study since 1984, the home, as it were, was apparently based on mammoth bones. The team’s findings are to be published in the science journal Quaternary International. http://phys.org/news243509025.html Other Sciences Mon, 19 Dec 2011 09:24:03 EST news243509025 Scientists from Japan and Russia believe it may be possible to clone a mammoth after finding well-preserved bone marrow in a thigh bone recovered from permafrost soil in Siberia, a report said Saturday. http://phys.org/news242227723.html Biology Sun, 04 Dec 2011 14:20:01 EST news242227723 Was it humans or climate change that caused the extinctions of the iconic Ice Age mammals (megafauna) such as the woolly rhinoceros and woolly mammoth? http://phys.org/news239597297.html Biology Fri, 04 Nov 2011 03:48:45 EST news239597297 The blood from woolly mammoths -- those extinct elephant-like creatures that roamed the Earth in pre-historic times -- is helping scientists develop new blood products for modern medical procedures that involve reducing patients' body temperature. The report appears in ACS' journal Biochemistry. http://phys.org/news235217045.html Chemistry Wed, 14 Sep 2011 11:04:51 EST news235217045 Scientists were surprised at how fast bacteria developed resistance to the miracle antibiotic drugs when they were developed less than a century ago. Now scientists at McMaster University have found that resistance has been around for at least 30,000 years. http://phys.org/news234015304.html Biology Wed, 31 Aug 2011 13:15:29 EST news234015304 Mammoths were a diverse genus that roamed across Eurasia and North America during the Pleistocene era. In continental North America, at least two highly divergent species have long been recognized – woolly mammoths (Mammuthus primigenius) and Columbian mammoths (M. columbi). But new genetic evidence published in BioMed Central's open access journal Genome Biology suggests that these species may have been closely related enough to mate when they had the chance. http://phys.org/news225988512.html Biology Mon, 30 May 2011 20:00:04 EST news225988512 Excited archeologists in California are rubbing their hands: after three years' back-breaking work they are finally, painstakingly revealing the face of Zed, the ice age mammoth. http://phys.org/news219645837.html Other Sciences Fri, 18 Mar 2011 06:30:01 EST news219645837 (AP) -- With a dental pick in hand, Karin Rice delicately scraped off a clump of asphalt from a pelvic bone belonging to a horse that roamed Los Angeles tens of thousands of years ago. http://phys.org/news218876422.html Other Sciences Wed, 09 Mar 2011 07:01:20 EST news218876422 Mammoths, which went extinct about 10,000 years ago, may once again walk the Earth. http://phys.org/news214406296.html Biology Sun, 16 Jan 2011 13:18:30 EST news214406296 Contrary to the belief of many scientists (as well as many members of the public), new research confirms that Africa has two—not one—species of elephant. Scientists from Harvard Medical School, the University of Illinois, and the University of York in the United Kingdom used genetic analysis to prove that the African savanna elephant and the smaller African forest elephant have been largely separated for several million years. http://phys.org/news212175742.html Biology Tue, 21 Dec 2010 17:49:38 EST news212175742 (AP) -- Wild horses have returned to northern Siberia. So have musk oxen, hairy beasts that once shared this icy land with woolly mammoths and saber-toothed cats. Moose and reindeer are here, and may one day be joined by Canadian bison and deer. http://phys.org/news210136812.html Space & Earth Sun, 28 Nov 2010 03:20:46 EST news210136812 (PhysOrg.com) -- New research challenges the controversial theory that the impact of an ancient comet devastated the Clovis people, one of the earliest known cultures to inhabit North America. http://phys.org/news204991757.html Other Sciences Wed, 29 Sep 2010 15:09:36 EST news204991757 A team made up of members of the University of Oviedo (UO) and the Complutense University of Madrid (UCM) have gathered together all findings of the woolly mammoth, the woolly rhinoceros and the reindeer in the Iberian Peninsula to show that, although in small numbers, these big mammals, prehistoric indicators of cold climates, already lived in this territory some 150,000 years ago. http://phys.org/news203076360.html Other Sciences Tue, 07 Sep 2010 11:30:07 EST news203076360
