Several theories have been proposed by scientists to explain the two mass extinction events which took place on the earth 250 and 200 million years ago. The Permian-Triassic catastrophe (250 million years ago) was the worst of all five of the mass extinction events to ever have befallen the earth. It eradicated almost 95% of […]

September 6th, 2012 riffin Dr. Eliseu Vieira Dias of the State University of Western Paraná (UNIOESTE) has announced the discovery of a new species of deep-bodied fish that prowled ancient rivers and lakes in the South American part of Gondwana during Permian period. A fossil of Paranaichthys longianalis (E.V. Dias) A paper in the journal Zootaxa describes a new species […]

September 5th, 2012 riffin Fifty million years ago, India slammed into Eurasia, a collision that gave rise to the tallest landforms on the planet, the Himalaya Mountains and the Tibetan Plateau. India and Eurasia continue to converge today, though at an ever-slowing pace. University of Michigan geomorphologist and geophysicist Marin Clark wanted to know when this motion will end […]

September 5th, 2012 riffin The growth of high topography on the Tibetan Plateau in Sichuan, China, began much earlier than previously thought, according to an international team of geologists who looked at mountain ranges along the eastern edge of the plateau. The Indian tectonic plate began its collision with Asia between 55 and 50 million years ago, but “significant […]

September 4th, 2012 riffin For the first time, the presence of large bodied herbivorous dinosaurs in Antarctica has been recorded. Until now, remains of sauropoda — one of the most diverse and geographically widespread species of herbivorous dinosaurs — had been recovered from all continental landmasses, except Antarctica. Dr. Ignacio Alejandro Cerda, from CONICET in Argentina, and his team’s […]

September 3rd, 2012 riffin When Apollo punished King Midas by giving him donkey ears, only the king and his barber knew. Unable to keep a secret, the barber dug a hole, whispered into it, “King Midas has donkey ears,” and filled the hole. But plants sprouted from the hole, and with each passing breeze, shared the king’s secret. Earth, […]

September 3rd, 2012 riffin As the world looks for more energy, the oil industry will need more refined tools for discoveries in places where searches have never before taken place, geologists say. One such tool is a new sediment curve (which shows where sediment-on-the-move is deposited), derived from sediments of the Paleozoic Era 542 to 251 million years ago, […]

September 2nd, 2012 riffin The potential of the ichnofossil record for exploring the evolution of behavior has never been fully realized. Some of this is due to the nature of the trace fossil record itself. Equally responsible is the separation of ichnology from the relevant areas of modern behavioral biology. The two disciplines have virtually no concepts, methods, or […]

September 2nd, 2012 riffin Scientists at Scripps Institution of Oceanography at UC San Diego have come a step closer to deciphering some of the basic mysteries and mechanisms behind earthquakes and how average-sized earthquakes may evolve into massive earthquakes. In a paper published in the Aug. 30 issue of the journal Nature, Scripps scientists Kevin Brown and Yuri Fialko describe […]

September 1st, 2012 riffin Scientists have identified several of the “biggest, baddest” theropods, and everyone asks, “Which one is the very biggest?” Giganotosaurus? Spinosaurus? T. rex? Acrocanthosaurus? “I think they’re all reaching the maximum size a two-legged, large-bodied carnivore can get,” explains Peter Larson, T. rex expert (Wyrex is his eighth rex excavation!). “All of these creatures are hovering at around the same size, […]
