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...

A recent study has shown that tiny slivers of diamond forged on an infant Earth may contain the earliest traces of life. The crystals contain a form of carbon often associated with plants and bacteria. The researchers caution that their results are not definitive proof of early life but do "not exclude" the possibility. "We're all a little sceptical," said Dr Martin Whitehouse of the Swedish Museum of Natural History and one of the authors of the paper. If the study is proven to be true then...

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...

A geologist from the University of Leicester has proposed an immense (1.5km) exhibition to illustrate the vastness of geological time and to give a vivid perspective of how quickly human activity is changing the climate. Sediments accumulate on deep ocean floors at a rate of a few centimeters every thousand years. The study of this "“ called stratigraphy "“ involves drilling vertically down into the sea bed to extract a sample core which gives a picture of continually changing...

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...

University Park, Pa. -- A switch from predominantly undersea volcanoes to a mix of undersea and terrestrial ones shifted the Earth's atmosphere from devoid of oxygen to one with free oxygen, according to geologists. "The rise of oxygen allowed for the evolution of complex oxygen-breathing life forms," said Lee R. Kump, professor of geoscience, Penn State. Before 2.5 billion years ago, the Earth's atmosphere lacked oxygen. However, biomarkers in rocks 200 million years older than that period,...

Boulder, Colo. - A new study of melted rock ejected far from the Yucatan's Chicxulub impact crater bolsters the idea that the famed impact was too early to have caused the mass extinction that killed the dinosaurs 65 million years ago. A careful geochemical fingerprinting of glass spherules found in multiple layers of sediments from northeast Mexico, Texas, Guatemala, Belize and Haiti all point back to Chicxulub as their source. But the analysis places the impact at about 300,000 years...

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

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...

Image Caption: Head of Tenontosaurus, Institut de paléontologie humaine, Paris, France. Credit: Rémih/Wikipedia (CC BY-SA 3.0) Tenontosaurus, meaning “sinew lizard”, is a genus of medium to large sized ornithopod dinosaur. The genus is known from the late Aptian to Albian ages of the middle Cretaceious period sediments of western North America, dating roughly between 115 to 108 million years ago. It was formerly thought to be a ‘hypsilophodont’, but since Hypsilophodontia is no...

The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...

The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...
