A U.S. scientist says he's found evidence dinosaurs may have survived for 500,000 years in New Mexico and Colorado after the Cretaceous extinctions. Jim Fassett, an emeritus scientist with the U.S. Geological Survey in Santa Fe, N.M., said he based his conclusions on detailed chemical investigations of the dinosaur bones, and evidence for the age of the rocks in which they were found in the Ojo Alamo Sandstone in the San Juan Basin. The great difficulty with this hypothesis -- that these are...

According to researchers, a wide-hipped Homo erectus fossil found in Ethiopia suggests that females of the pre-human species gave birth to developed babies with large heads. The finding leads some researchers to believe that helpless babies came along late in human evolution. "We could look at this pelvis and then, using a series of measurements, we can calculate ... how big the baby's head could be at birth," said Scott Simpson, a paleontologist at Case Western Reserve University. Simpson...

U.S. scientists say the Earth is in the midst of its sixth mass extinction of plants and animals, with nearly 50 percent of all species disappearing. Biologists at the University of California-Santa Barbara say they are working to determine which species must be saved. "The current extinction event is due to human activity, paving the planet, creating pollution, many of the things that we are doing today," said study co-author Assistant Professor Bradley Cardinale. "The Earth might well...

By Rick Steelhammer What's 12 feet long, has 6-inch claws and weighs a ton or more? It's Megalonyx jeffersonii, and starting Saturday, a precise scientific replica of its skeletal remains will be on display at the West Virginia Geological Survey Museum near Morgantown. In March, the Legislature designated the Megalonyx jeffersonii the official state fossil, since the first known specimen of the prehistoric species was found in a West Virginia cave more than 200 years ago. Megalonyx...

By Robert S. Boyd / McClatchy Newspapers It was the greatest mass murder of all time - poison everywhere, billions slain - but the killers have never been positively identified. An estimated 95 percent of marine species and 85 percent of land creatures died, said Peter Ward, a paleobiologist at the University of Washington in Seattle. Scientists call it "The Great Dying." Life took millions of years to recover. Scientific sleuths now think they're making progress toward learning what...

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...

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

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

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...
