Paleontologists have long known that dinosaurs had tiny brains, but they had no idea the beasts were such airheads. A new study by Ohio University researchers Lawrence Witmer and Ryan Ridgely found that dinosaurs had more air cavities in their heads than expected. By using CT scans, the scientists were able to develop 3-D images […]

October 30th, 2012 riffin “Bones upon bones, we couldn’t believe our eyes,” says Oliver Wings, paleontologist and guest researcher at the Museum für Naturkunde in Berlin. He was describing the spectacular find of some 1800 fossilized mesa chelonia turtles from the Jurassic era in China’s northwest province of Xinjiang. Wings and the University of Tübingen’s fossil turtle specialist, Dr. […]

October 29th, 2012 Riffin The Caribbean islands have been pushed east over the last 50 million years, driven by the movement of Earth’s viscous mantle against the more rooted South American continent, reveals new research by geophysicists from USC. The results, published August 19 inNature Geoscience, give us a better understanding of how continents resist the constant movement of […]

October 28th, 2012 riffin The ostrich-like dinosaurs in the original Jurassic Park movie were portrayed as a herd of scaly, fleet-footed animals being chased by a ferocious Tyrannosaurus rex. New research published in the journal Sciencereveals this depiction of these bird-mimic dinosaurs is not entirely accurate — the ornithomimids, as they are scientifically known, should have had feathers and wings. The […]
Ancient Protein Preservation from dinosaur bone
October 26th, 2012 Riffin A team of researchers from North Carolina State University and the Palo Alto Research Center (PARC) has found more evidence for the preservation of ancient dinosaur proteins, including reactivity to antibodies that target specific proteins normally found in bone cells of vertebrates. These results further rule out sample contamination, and help solidify the case for […]
100-Million-Year-Old Coelacanth Fish Discovered in Texas Is New Species from Cretaceous
October 25th, 2012 Riffin A new species of coelacanth fish has been discovered in Texas. The species is now the youngest coelacanth from Texas; fish jaw and cranial material indicate a new family — Dipluridae — that was evolutionary transition between two previously known families. Pieces of tiny fossil skull found in Fort Worth have been identified as 100 […]

October 24th, 2012 riffin What makes some ocean animals more prone to extinction than others? A new study of marine fossils provides a clue. An analysis of roughly 500 million years of fossil data for marine invertebrates reveals that ocean animals with small geographic ranges have been consistently hard hit — even when populations are large, the authors report. […]

October 22nd, 2012 riffin The pectoral and pelvic girdles support paired fins and limbs, and have transformed significantly in the diversification of gnathostomes or jawed vertebrates (including osteichthyans, chondrichthyans, acanthodians and placoderms). For instance, changes in the pectoral and pelvic girdles accompanied the transition of fins to limbs as some osteichthyans (a clade that contains the vast majority of […]
Scientists Identify Likely Origins of Vertebrate Air Breathing
October 21st, 2012 riffin University of Alaska Fairbanks scientists have identified what they think is the ancestral trait that allowed for the evolution of air breathing in vertebrates. They will present their research at the 42nd annual meeting of the Society for Neuroscience Oct. 17 in New Orleans. “To breathe air with a lung you need more than a […]

October 20th, 2012 riffin In “Jurassic Park,” scientists extract 80-million-year-old dino DNA from the bellies of mosquitoes trapped in amber. Researchers may never be able to extract genetic material that old and bring a T. rex back to life, but a new study suggests DNA can survive in fossils longer than previously believed. The oldest DNA samples ever recovered […]
