A study published in the current issue of Science challenges the long-held belief that diversity of marine species has been increasing continuously since the origin of animals. Dr. Thomas D. Olszewski, a geology and geophysics professor at Texas A&M University, has been a part of the international team that carried out this decade-long study, which concludes that most of the diversification occurred early on "“ relatively speaking. "The general understanding for many decades has...

Human ancestor's teeth yields new cluesTiny marks on the teeth of an ancient human ancestor known as the "Nutcracker Man" may upset current evolutionary understanding of early hominid diet.Using high-powered microscopes, researchers looked at rough geometric shapes on the teeth of several Nutcracker Man specimens and determined that their structure alone was not enough to predict diet.Peter Ungar, professor of anthropology at the University of Arkansas in Fayetteville, contends the finding...

In a paper published in this month's "ËœGeophysical Journal International', Dr Graeme Eagles from the Earth Sciences Department at Royal Holloway, University of London, reveals how one of the largest continents ever to exist met its demise.Gondwana was a "Ëœsupercontinent' that existed between 500 and 180 million years ago. For the past four decades, geologists have debated how Gondwana eventually broke up, developing a multitude of scenarios which can be loosely grouped...

Researchers in Brazil reported their discovery of a new marine crocodile species on Wednesday, showing that the reptiles survived the mass extinction of dinosaurs 65 million years ago.In the report published in the Proceedings of Royal Society B research journal, paleontologists said they found the new dyrosaurid crocdylomorph in the Poty Quarry, a limestone quarry located close to Recife in northeastern Brazil. Researchers suggested that the Guarinisuchus munizi survived the...

Paleontologists from University College London (UCL) and Stony Brook University in New York have identified a giant frog fossil from Madagascar, given the name Beelzebufo (pronounced bee-el-zeh-BOOF-oh), which means "Ëœthe frog from Hell'.The fossil is 70 million years old, and of a type once thought unique to South America, providing evidence for a new theory that Madagascar, India and South America were linked until late in the age of dinosaurs. The frog resembles today's living...

AUSTIN, Texas -- The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago.The Chicxulub crater was formed when an asteroid struck on the coast of the Yucatan Peninsula. Most scientists agree the impact played a major role in the "KT Extinction Event" that caused the extinction of most life on Earth, including...

By Lee, Seung-Bae Choi, Duck K ABSTRACT- The Pseudokoldinioidia Fauna is a newly documented uppermost Cambrian trilobite assemblage from the Dongjeom Formation of the Taebaek Group, Taebaeksan Basin, Korea. It is characterized by low species diversity comprising six trilobite taxa: Micragnostus chiushuensis, Koldinioidia typicalis, leiostegiid genus and species indeterminate, Pseudokoldinioidia perpetis, Onychopyge borealis, and pilekiid genus and species indeterminate. Of these, special...

WASHINGTON -- Scientists, wringing their hands over the identity of the famed "hobbit" fossil, have found a new clue in the wrist. Since the discovery of the bones in Indonesia in 2003, researchers have wrangled over whether the find was an ancient human ancestor or simply a modern human suffering from a genetic disorder. Now, a study of the bones in the creature's left wrist lends weight to the human ancestor theory, according to a report in Friday's issue of the journal Science. The wrist...

The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 65 million years ago has been traced back to a breakup event in the main asteroid belt. The finding provides insights into one of the most important extinction events in Earth's history. Known as the Cretaceous-Tertiary (K-T) extinction, this impact event signaled a dramatic change in the evolutionary history of Earth. Understanding the origins and effects of this event can not only teach us about the...

By Prendergast, Kate Our prehistoric ancestors survived rapid climate change and rising temperatures as extreme as those we face today, says Kate Prendergast. What can they tell us about global warming? BETWEEN 18- 20,000 YEARS AGO, average temperatures in Europe probably fell to at least 10[degrees]C below the levels they are today. In the last great Ice Age, glaciers expanded rapidly and covered large areas of northern and central Europe in ice sheets. Much of Europe resembled tundra and...

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

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...
