Drilling cores from Switzerland have revealed the oldest known fossils of the direct ancestors of flowering plants. These beautifully preserved 240-million-year-old pollen grains are evidence that flowering plants evolved 100 million years earlier than previously thought, according to a new study in the open-access journal Frontiers in Plant Science. Flowering plants evolved from extinct plants […]

Dinosaur Wind Tunnel Test Provides New Insight Into the Evolution of Bird Flight
October 2nd, 2013 Riffin A study into the aerodynamic performance of feathered dinosaurs, by scientists from the University of Southampton, has provided new insight into the evolution of bird flight. In recent years, new fossil discoveries have changed our view of the early evolution of birds and, more critically, their powers of flight. We now know about a number […]
Pakistan’s new island, pushed up by earthquake
October 1st, 2013 Riffin (Associated Press) — Alongside the carnage of Pakistan’s massive earthquake came a new creation: a small island of mud, stone and bubbling gas pushed forth from the seabed. Experts say the island was formed by the massive movement of the earth during the 7.7-magnitude quake that hit Pakistan’s Baluchistan province on Tuesday, Sept. 24, 2013. […]
“Entelognathus primordialis” New Fish Fossil From China
September 30th, 2013 Riffin A leading British scientist has said that the discovery of a 419-million-year-old fish fossil in China is a stunning and spectacular development. Palaeobiologist Matt Friedman told the BBC that the fish provided crucial evidence about the evolutionary development of jawed vertebrates. As a remote relative of humans, it provides important evolutionary clues. “It is the […]
Ancient Soils Reveal Clues to Early Life On Earth
September 29th, 2013 Riffin Oxygen appeared in the atmosphere up to 700 million years earlier than we previously thought, according to research published today in the journal Nature, raising new questions about the evolution of early life. Researchers from the University of Copenhagen and University of British Columbia examined the chemical composition of three-billion-year-old soils from South Africa — […]
Oldest Lizard-Like Fossil Yet to Be Found Hints at Scaly Origins
September 28th, 2013 Riffin The fossilised remains of a reptile closely related to lizards are the oldest yet to be discovered. Two new fossil jaws discovered in Vellberg, Germany provide the first direct evidence that the ancestors of lizards, snakes and tuatara (known collectively as lepidosaurs) were alive during the Middle Triassic period — around 240 million years ago. […]
Late Cretaceous Period Was Likely Ice-Free
September 27th, 2013 Riffin For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University of Missouri researcher has found evidence suggesting that no ice sheet formed at this time. This finding could help environmentalists […]
Seismologists Puzzle Over Largest Deep Earthquake Ever Recorded
September 22nd, 2013 Riffin A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013, has left seismologists struggling to explain how it happened. At a depth of about 609 kilometers (378 miles), the intense pressure on the fault should inhibit the kind of rupture that took place. “It’s a mystery how these earthquakes […]
Geologists Simulate Deep Earthquakes in Lab
September 21st, 2013 Riffin More than 20 years ago, geologist Harry Green, now a distinguished professor of the graduate division at the University of California, Riverside, and colleagues discovered a high-pressure failure mechanism that they proposed then was the long-sought mechanism of very deep earthquakes (earthquakes occurring at more than 400 km depth). The result was controversial because seismologists […]
Oldest and Youngest Stag-Moose in North America
September 20th, 2013 Riffin Matthew Hill has identified countless bones found by farmers, fishermen, rock hounds and heavy equipment operators. Most of the remains turn out to be deer, bison, horse or cow bones, or simply odd looking rocks. But some discoveries turn out to be highly unusual, as was the case with an antler from an extinct Ice […]
