According to an article published online December 2012 in the journal of Chinese Science Bulletin (Vol.57, No.36), Dr. JIN Changzhu, Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences, and his team described a new species of trilophodont gomphotheres, Sinomastodon jiangnanensis, from the Early Pleistocene Renzidong Cave deposits in Anhui Province, Eastern China. The specimen, an almost complete skull with mandible and dentition, is the first discovery of a Quaternary Sinomastodon skull from China and has significant implications for discussing the evolution, dispersion and related paleoecological variation of Sinomastodon during the Quaternary. http://phys.org/news274966507.html Other Sciences Mon, 17 Dec 2012 11:35:23 EST news274966507 (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 Past waves of extinctions which removed some of the world's largest animals were caused by both people and climate change, according to new research from the University of Cambridge. Their findings were reported today, 05 March, in the journal Proceedings of the National Academy of Sciences (PNAS). http://phys.org/news250166482.html Biology Mon, 05 Mar 2012 15:00:08 EST news250166482 (AP) -- Scientists say an excavation site in western Colorado has unearthed fossils for ice age mastodons of all ages. http://phys.org/news226380246.html Other Sciences Sat, 04 Jun 2011 04:24:18 EST news226380246 (AP) -- Scientists say results from the first radiocarbon tests show that some of the Ice Age animal bones being excavated in western Colorado are at least 43,500 years old. http://phys.org/news208837795.html Other Sciences Sat, 13 Nov 2010 02:40:01 EST news208837795 Saber-toothed cats may be best known for their supersized canines, but they also had exceptionally strong forelimbs for pinning prey before delivering the fatal bite, says a new study in the journal PLoS ONE. http://phys.org/news197350513.html Other Sciences Sat, 03 Jul 2010 04:35:47 EST news197350513 A new analysis of the extinction of woolly mammoths and other large mammals more than 10,000 years ago suggests that they may have fallen victim to the same type of "trophic cascade" of ecosystem disruption that scientists say is being caused today by the global decline of predators such as wolves, cougars, and sharks. http://phys.org/news197124739.html Biology Thu, 01 Jul 2010 00:00:16 EST news197124739 The balance of biodiversity within North American small-mammal communities is so out of whack from the last episode of global warming about 12,000 years ago that the current climate change could push them past a tipping point, with repercussions up and down the food chain, say Stanford biologists. The evidence lies in fossils spanning the last 20,000 years that the researchers excavated from a cave in Northern California. http://phys.org/news193846393.html Biology Sun, 23 May 2010 15:13:39 EST news193846393
