Ancient DNA retrieved from extinct horse species from around the world has challenged one of the textbook examples of evolution - the fossil record of the horse family Equidae over the past 55 million years. The study, published today in the Proceedings of the National Academy of Sciences, involved an international team of researchers and the Australian Centre for Ancient DNA (ACAD) based at the University of Adelaide. Only the modern horse, zebras, wild asses and donkey survive today, but...

Roughly 15,000 years ago, at the end of the last ice age, North America's vast assemblage of large animals "” including such iconic creatures as mammoths, mastodons, camels, horses, ground sloths and giant beavers "” began their precipitous slide to extinction. And when their populations crashed, emptying a land whose diversity of large animals equaled or surpassed Africa's wildlife-rich Serengeti plains then or now, an entirely novel ecosystem emerged as broadleaved trees once...

Homo floresiensis not diseased sub-population of healthy humans Researchers from Stony Brook University Medical Center in New York have confirmed that Homo floresiensis is a genuine ancient human species and not a descendant of healthy humans dwarfed by disease. Using statistical analysis on skeletal remains of a well-preserved female specimen, researchers determined the "hobbit" to be a distinct species and not a genetically flawed version of modern humans. Details of the study appear in the...

New research suggests that the giant deer, also known as the giant Irish deer or Irish elk, one of the largest deer species that ever lived, likely died off because of climate change, BBC News reported. The giant deer (Megaloceros giganteus), which had massive antlers, suddenly went extinct some 10,600 years ago and a new study of its teeth suggests that as conditions became colder and drier in Ireland at the time, fewer plants grew, gradually starving the deer. Initial ideas for why the...

Despite their fearsome fangs, male sabertoothed cats may have been less aggressive than many of their feline cousins, says a new study of male-female size differences in extinct big cats. Commonly called the sabertoothed tiger, Smilodon fatalis was a large predatory cat that roamed North and South America about 1.6 million to 10,000 years ago, when there was also a prehistoric cat called the American lion. A study appearing in the November 5 issue of the Journal of Zoology examined size...

An infant woolly mammoth that has been frozen for 40,000 years in the Siberian permafrost is so well preserved that there are still traces of her mother's milk in her stomach. Three years after reindeer herders dug up the fossil, Lyuba is going to Chicago to star in a mammoth and mastodons display at the Field Museum. The exhibition debuts March 5 and will be open to the public until September 6. "There's a visceral awe that takes hold of you in looking at a specimen like Lyuba, and the...

An almost fully preserved woolly mammoth discovered in Siberia will makes its U.S. debut at Chicago's Field Museum of National History, officials say. Daniel Fisher, lead curator of the Mammoths and Mastodons exhibit coming to the Field Museum next spring, said the baby mammoth nicknamed Lyuba will be a great addition to the museum, the Chicago Tribune reported Thursday. We had hoped to be able to present the best of the best, Fisher said. And we've got the best of the best. The mammoth was...

A mastodon tooth more than 8 inches long turned up on a stream bank in Wisconsin, state officials say. Cale Severson, a Department of Natural Resources employee, discovered the huge tooth while working on a trout habitat project in Grant County in southeastern Wisconsin, the department said Friday. What Severson calls the find of a lifetime came as he examined rocks that had been dumped by flooding. I noticed something really odd in that pile -- seeing just two of the five cusps -- and...

The use of tools by hominins - the primate group which includes humans (Homo) and chimpanzees and bonobos (Pan) - has been extensively researched by archaeologists and primatologists, both of who manifest the relevance of tool-use in understanding technology and the origins of human behavior. However, recent research has highlighted the need to include other species such as gorillas and orangutans, as well as other extinct primate groups prior to hominins, in order to situate, for the first...

Scientists have recently unearthed the fossilized remains of four woolly mammoths in a southern province of Spain, lending support to theories that the last great Ice Age reached much further south than paleontologists had previously thought. Remains of the four adult male mammoths were discovered in a peat bog in the Granada basin in Andalusia, Spain's southernmost autonomous community.  The dig was part of a joint scientific project of four research institutions"”the Quaternary...

Australopithecus garhi is a gracile australopithecine species whose fossils were discovered in 1996 by a research team led by Ethiopian paleontologist Berhane Asfaw ad Tim White, an American paleontologist. The remains are believed to be a human ancestor species and most likely the direct ancestor to the human genus Homo. Tim White was the scientist to find the first of the key A. garhi fossils in 1996 within the Bouri Formation found in the Middle Awash of Ethiopia’s Afar Depression....

Homo floresiensis

Homo floresiensis Homo floresiensis, or Flores Man, nicknamed “hobbit” and “Flow”, is an extinct species in the genus Homo. The remains of an individual that would have stood about 3 feet in height were uncovered in 2003 on the island of Flores in Indonesia. Incomplete skeletons of nine individuals have been recovered, including one complete cranium. These remains have been the focus of intense research to establish whether they represent a species distinctive from modern humans....

Panthera leo spelaea

Commonly known as the Eurasian cave lion or the European cave lion, Panthera leo spelaea is an extinct subspecies of lion. It is thought to have lived during the Pleistocene epoch, and may have lived in the Balkans in southeastern Europe until 2,000 years ago. The range of this cave lion would have included northwestern North America, Asia, and areas of Europe and would have extended from Germany, Spain, and Great Britain to the Yukon Territory. Its range also extended from Turkistan to...

The stag-moose (Cervalces scotti) is also known as the stag moose and was actually a deer that resembled a moose. It resided in North America during the Pleistocene era. Its range included New Jersey and Iowa, reach north from Arkansas to Southern Canada. It inhabited wetlands in these areas. This animal had long legs, a head resembling an elk, and huge, complex antlers. The stag-moose became extinct during the mass extinction of large mammals that occurred in the last Ice Age on North...

Shrub-ox, Euceratherium collinum
2012-05-10 05:18:10

The shrub-ox (Euceratherium collinum) is a close relative of the modern musk-ox, and is an extinct member of the family Bovidae. It inhabited North America during the late Pleistocene, appearing before the first bovids entered North America from Eurasia. These muskoxen became extinct approximately 11,500 years ago. The shrub-ox was very large, approximately in between the sizes of a musk-ox and an American Bison. Research done on pellets left by these oxen shows that they browsed for food...
