Aquilops : Oldest horned dinosaur species in North America

cientists have named the first definite horned dinosaur species from the Early Cretaceous in North America, according to a study published December 10, 2014 in the open-access journal PLOS ONE by Andrew Farke from Raymond M. Alf Museum of Paleontology and colleagues. The limited fossil record for neoceratopsian–or horned dinosaurs–from the Early Cretaceous in North […]

volcanoes may be much closer than thought

Credit: Virginia Tech   Traditional thought holds that hot updrafts from the Earth’s core cause volcanoes, but researchers say eruptions may stem from the asthenosphere, a layer closer to the surface. Credit: Virginia Tech A long-held assumption about the Earth is discussed in today’s edition of Science, as Don L. Anderson, an emeritus professor with […]

Lava erupting on sea floor linked to deep-carbon cycle

Scientists from the Smithsonian and the University of Rhode Island have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the […]

Erosion may trigger earthquakes

Researchers from laboratories at Géosciences Rennes (CNRS/Université de Rennes 1)*, Géosciences Montpellier (CNRS/Université de Montpellier 2) and Institut de Physique du Globe de Paris (CNRS/IPGP/Université Paris Diderot), in collaboration with a scientist in Taiwan, have shown that surface processes, i.e. erosion and sedimentation, may trigger shallow earthquakes (less than five kilometers deep) and favor the […]

Tectonic plates not rigid, deform horizontally in cooling process

The puzzle pieces of tectonic plates that make up the outer layer of earth are not rigid and don’t fit together as nicely as we were taught in high school. A study published in the journal Geology by Corné Kreemer, an associate professor at the University of Nevada, Reno, and his colleague Richard Gordon of […]

Fossil finds behind mall causing excitement

A dig site, in New Jersey, is yielding exciting finds: the fossils of animals believed killed around the same time the dinosaurs disappeared. Uncovering the mystery has taken a cast of thousands. Behind a strip mall in southern New Jersey, paleontologists from Drexel University are traveling 65 million years into the past. This quarry could […]

How the tortoise’s ribs got embedded in its shell……….

Through the careful study of modern and early fossil tortoise, researchers now have a better understanding of how tortoises breathe and the evolutionary processes that helped shape their unique breathing apparatus and tortoise shell. The findings published in a paper, titled: Origin of the unique ventilatory apparatus of turtles, in the scientific journal, Nature Communications, […]

Kung fu stegosaur: Lethal fighters when necessary

Stegosaurs might be portrayed as lumbering plant eaters, but they were lethal fighters when necessary, according to paleontologists who have uncovered new evidence of a casualty of stegosaurian combat. The evidence is a fatal stab wound in the pubis bone of a predatory allosaur. The wound — in the conical shape of a stegosaur tail […]
