Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered a new species of a small horse that lived 4.4 million years ago in Ethiopia. The Eurygnathohippus woldegabrieli fossils were found in the Gona area of the Afar region in 2001. The ancient horse was among a diverse array of animals that lived in the same areas as the ancient human ancestor Ardipithecus ramidus, or Ardi. The ancient horse species was about the size of a small zebra and had three-toed hooves....

2013-11-23 05:08:21

April Flowers for redOrbit.com - Your Universe Online At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history. Previous research has suggested that contemporaneous volcanic eruptions in Siberia might have triggered this extinction. A new study, published in the journal Geology, reveals that the atmospheric effects of these eruptions could have been...

redOrbit Staff & Wire Reports - Your Universe Online The discovery of a lone tooth in the Riversleigh World Heritage Area of Queensland, Australia, has led to the classification of a new, giant, now-extinct species of platypus known as the Obdurodon tharalkooschild. The new species in the duck-billed, egg-laying mammal’s family is detailed in the latest edition of the Journal of Vertebrate Paleontology, and while the precise age of the fossil has not been yet been determined, it...

Mass Extinction During The Pangea Integration
2013-11-04 03:21:57

redOrbit Staff & Wire Reports - Your Universe Online The integration of Pangea that began during the early Permian period may have caused the environment to deteriorate, playing a role in the mass extinction event that occurred 250 million years ago, according to research appearing in the most recent edition of the journal Science China Earth Sciences. In the study, co-authors, professor Yin Hongfu and Dr. Song Haijun of the State Key Laboratory of Geobiology and Environmental...

Dwarfism In Mammals Also Occurred During Second Warming Period
2013-11-03 05:03:03

redOrbit Staff & Wire Reports - Your Universe Online While scientists have known for several years that some mammals became smaller during a period of warming known as the Paleocene-Eocene Thermal Maximum (PETM), researchers from the University of Michigan have found a second instance of mammalian “dwarfing” attributable to increasing temperatures. During the PETM, which occurred approximately 55 million years ago, mammals such as primates and groups that include deer and horses...

[ Watch the Video: Ancient Homo Species Were Merely Variations On A Theme ] redOrbit Staff & Wire Reports - Your Universe Online An analysis of a 1.8 million-year-old human skull suggests that the earliest members of our Homo genus actually belonged to a single species, a finding that contradics previous beliefs that there were several different human species walking the Earth during that time. The fossil, which was unearthed in Dmanisi, Georgia, is the first complete skull of an...

Evidence Suggests Recycling May Have Started With Early Hominids
2013-10-12 08:28:18

[ Watch the Video: Recycling Was In For Early Man ] redOrbit Staff & Wire Reports – Your Universe Online Despite the general perception that recycling is a fairly modern phenomenon, there is growing evidence it dates back to the days of the early hominids, researchers said this week during a four-day conference at Tel Aviv University in Israel. “For the first time we are revealing the extent of this phenomenon, both in terms of the amount of recycling that went on and the...

Mammal Diversity Faltered When Flowering Plants Arrived
2013-10-02 16:02:24

Brett Smith for redOrbit.com - Your Universe Online As mammals were trying to emerge from the shadows of dinosaurs 100 million years ago, there was a dramatic proliferation of flowering plant species. However, instead of early mammals benefiting from new food and shelter opportunities that would have been provided by the plants, they experienced a decline during the mid-Cretaceous. Using a morphological analysis, two researchers were able to provide these new insights about mammalian...

Mapinguari The mapinguari or mapinguary is an ape-like cryptid said to inhabit the Amazon rainforests of Brazil and Bolivia. It is also known as the Isnashi. Several attempts to find physical evidence that the creature exists have been conducted. Samples have been gathered, but when analyzed it was found to be from known animals and some of the castings of tracks were inconclusive. Native folklore has described the creature as having only one eye, long claws, backward feet, a...

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...

Thescelosaurus
2013-04-28 18:48:11

Thescelosaurus, meaning “godlike”, “wondrous”, or “marvelous” and “lizard” was a genus of small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. It was a member of the last dinosaurian fauna before the Cretaceous-Paleogene extinction event around 65.5 million years ago. The completeness and preservation of many of its specimens illustrate that it might have preferred to live near streams. This bipedal ornithopod is known from...

Daspletosaurus

Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...
