Oceans May Change Drastically In The Future
2013-08-06 05:37:31

April Flowers for redOrbit.com - Your Universe Online A new study, led by Scripps Institution of Oceanography, reveals the look of the oceans will change drastically in the future as the coming greenhouse world alters marine food webs and gives certain species advantages over others, if history's closest analog is any indication. Richard Norris, paleobiologist at Scripps Institution of Oceanography, UC San Diego, worked with an international team of scientists to show the ancient...

Extinct Hobbit Resembled Humans Not Apes
2013-07-24 10:37:41

Brett Smith for redOrbit.com - Your Universe Online According to a new report in the Journal of Archaeological Science, an ancient humanoid species referred to as the "hobbit" closely resembled humans and not apes as some experts previously thought. Archeologists first excavated remains of this three-foot-tall human-like primate from an Indonesian cave in 2003. Known to researchers by its scientific name Homo floresiensis, the species is believed to have been a contemporary of...

Ancient Sabre-Like Toothed Predator Had Weaker Bite Than Domestic Cat
2013-07-02 10:13:13

April Flowers for redOrbit.com - Your Universe Online Millions of years ago, a bizarre, pouched super-predator terrorized South America with huge saber-like teeth. New research from the University of New South Wales (UNSW), however, shows the Thylacosmilus atrox had a bite weaker than that of a domestic cat. Marsupials in Australia and America are among the closest living relatives of the extinct T. atrox, which had tooth roots extending rearwards almost into its small braincase....

Unique Dinosaur Roamed The Desert Of Supercontinent Pangea
2013-06-25 09:03:28

April Flowers for redOrbit.com - Your Universe Online Pangaea, a single supercontinent existing from 300-200 million years ago, dominated the Earth during the Permian era with animal and plant life dispersed broadly across the land. This disbursement is documented by identical fossil species found on multiple modern continents. A new study, from the Society of Vertebrate Paleontology, supports the idea that Pangaea had an isolated desert at the center of the supercontinent with unique...

Although scientists have known since the middle of the 19th century that the tropics are teeming with species while the poles harbor relatively few, the origin of the most dramatic and pervasive biodiversity on Earth has never been clear. New research sheds light on how that pattern came about. Furthermore, it confirms that the tropics have been and continue to be the Earth's engine of biodiversity. By examining marine bivalves (two-shelled mollusks including scallops, cockles and...

Four New Studies Show Early Humans Had A Diet Rich In Grass
2013-06-04 11:43:40

Lawrence LeBlond for redOrbit.com - Your Universe Online Four new studies have taken a new look at the diets of our ancestors and have found their behavior was a “game changer” for early humans some 3.5 million years ago. An ape-like diet that included grasses and sedges paved the way for a diet rich in grains, meats and dairy from grazing animals. In the first of the four studies, researchers from the University of Colorado Boulder conducted high-tech tests on tooth enamel...

Ichthyosaur Fossil Indicates Dolphin-Like Dinos Survived Into Jurassic
2013-05-15 14:43:09

Brett Smith for redOrbit.com - Your Universe Online A fossil previously used as a stepping stone for mules has deepened the mystery surrounding the evolution of ichthyosaurs, dolphin-like marine reptiles that were contemporaries of the dinosaurs. According to a newly published report in the journal“¯Biology Letters,“¯an analysis of the fossil, dubbed Malawania anachronus, has suggested that ichthyosaurs survived well into the...

Researchers Study Earliest Evidence Of Human Hunting And Scavenging
2013-05-11 08:19:44

April Flowers for redOrbit.com — Your Universe Online New light has been shed on the diet and food acquisition strategies of some of the earliest human ancestors in Africa, according to a new study led by Baylor University. Early tool making humans, known as Oldowan hominin, started to exhibit a number of physiological and ecological adaptations beginning around two million years ago. These adaptations, including an increase in brain and body size, heavier investment in their...

Picky Eating Was Critical In Saber-Tooth Tiger Extinction
2013-05-09 08:46:34

April Flowers for redOrbit.com - Your Universe Online During the Pleistocene epoch, an astounding diversity of large-bodied mammals inhabited the so-called “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 territory. Three types of large predators roamed the steppe during the Pleistocene, wolves, bears and large cats. After the end of the last ice age, only...

Ancient Hominid Study Reveals Early Similarities Between Humans And Apes
2013-04-12 09:07:49

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the largest studies on some of the most complete remains of early human ancestors has culminated in a comprehensive look into how an early hominid (Australopithecus sediba) moved and chewed. The study, collaborated on by an international team of scientists and published in six papers in the journal Science, details not only early traits but also describes notable features that set it apart from modern humans. The research...

Mapinguari
2014-04-22 13:41:18

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
2013-04-28 18:27:18

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...
