Permian Mass Extinction May Have Happened In The Blink Of An Eye
2014-02-11 05:07:01

April Flowers for redOrbit.com - Your Universe Online Approximately 252 million years ago, the largest mass extinction event in the history of animal life on Earth occurred — wiping out more than 96 percent of marine species and 70 percent of terrestrial species. This included the largest insects known to have inhabited the planet. Scientists have explored many theories to explain the cause of the end-Permian extinction, as it came to be known. Those theories include an asteroid...

2014-02-06 09:29:49

[ Watch the Video: Diet Changes Killed Off Woolly Mammoths ] Brett Smith for redOrbit.com - Your Universe Online Scientists have put forth many theories on why woolly mammoths and other large animals went extinct around 10,000 years ago, from the devastating effects of a comet impact to overhunting by humans. A new DNA-based study published in the journal Nature has found that the flowering plants these “megafauna” depended on disappeared from northern Asia and North America...

An Oxford University study has concluded that our ancient ancestors who lived in East Africa between 2.4 million-1.4 million years ago mainly ate tiger nuts (grass bulbs) supplemented with the odd grasshopper and worm An Oxford University study has concluded that our ancient ancestors who lived in East Africa between 2.4 million-1.4 million years ago survived mainly on a diet of tiger nuts. Tiger nuts are edible grass bulbs still eaten in parts of the world today. The study published in...

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....

Extinction Event During End Of The Permian Period Likely Due To Acid Rain
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...

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

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, 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...
