Ocean Acidification Rapid Compared To Ancient Times
2012-03-02 13:49:09

The world´s oceans may be acidifying more rapidly than they have at any time in the past 300 million years due to high levels of pollution, according to research published this week in the journal Science. Researchers, led by Columbia University´s Lamont-Doherty Earth Observatory and the University of Bristol, assessed a number of climate change events in Earth´s history, including an asteroid impact that wiped out the dinosaurs 65 million years ago. They warn that too...

Climate Change Drove Shrinkage In Ancient Horse
2012-02-24 05:39:51

The ancient sifrhippus, the earliest known horse, lived around 50 million years ago. It was very distinct in its appearance because it was only about the size of a modern day house cat, weighing in around 12 pounds. The horse lived in what is known as the Paleocene-Eocene Thermal Maximum (PETM), a 175,000 year period where the Earth's atmospheric temperature rose by about 10 degrees Fahrenheit, caused by a great release of carbon into the atmosphere and oceans. In response to the...

University of Miami study offers new geochemical clues to understand conditions just prior to major climatic event In a study published in the journal Geology, scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggest that the large changes in the carbon isotopic composition of carbonates which occurred prior to the major climatic event more than 500 million years ago, known as 'Snowball Earth,' are unrelated to worldwide glacial events. "Our...

A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction event at the end of the Cretaceous period that is famous for killing the dinosaurs 65 million years ago, according to two Princeton University reports that reject the prevailing theory that the extinction was caused by a single large meteorite. Princeton-led researchers found that a trail of dead plankton spanning half a million years provides a timeline that links the mass...

Researchers Find Freshwater Springs, Numerous Micro-organisms In The Dead Sea

[ Watch the Video ] Findings are the result of collaboration between researchers from Ben-Gurion University of the Negev and the Max Planck Institute of Marine Microbiology Ben-Gurion University of the Negev (BGU) researchers have discovered deep freshwater springs on the Dead Sea floor that feed into this rapidly dwindling body of water. In the first-ever Dead Sea diving expedition, the researchers also found new types of micro-organisms growing around fissures in the sea floor as...

BANGOR, Maine, May 25, 2011 /PRNewswire/ -- It's a time for reckless abandon, of char-grilled fish eaten at the water's edge, melon ice-cream melting over your chin, skinny-dipping and the smell of sun-tan lotion, coconut-based cocktails shared at twilight, and the squeak of fine white sand as you wander hand-in-hand down to the ocean. Summer is seen as the finest season for so many reasons: for children it's the freedom of no school, for adults the period to unwind, and for new-found...

More than 200 million years ago, mammals and reptiles lived in their own separate worlds on the supercontinent Pangaea, despite little geographical incentive to do so. Mammals lived in areas of twice-yearly seasonal rainfall; reptiles stayed in areas where rains came just once a year. Mammals lose more water when they excrete, and thus need water-rich environments to survive. Results are published in the Proceedings of the National Academy of Sciences.Aggregating nearly the entire landmass of...

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...

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...
