When Nicholas Longrich discovered a new dinosaur species with a heart-shaped frill on its head, he wanted to come up with a name just as flamboyant as the dinosaur’s appearance. Over a few beers with fellow paleontologists one night, he blurted out the first thing that came to mind: Mojoceratops. “It was just a joke, but […]

No Comments »Ammonites dined on plankton
August 12th, 2012 Riffin Powerful synchrotron scans of Baculites fossils found on American Museum of Natural History expeditions to the Great Plains suggests that the extinct group of marine invertebrates to which they belong, the ammonites, had jaws and teeth adapted for eating small prey floating in the water. One ammonite also provided direct evidence of a planktonic diet because it […]

August 12th, 2012 Riffin Mineral evolution posits that Earth’s near-surface mineral diversity gradually increased through an array of chemical and biological processes. A dozen different species in interstellar dust particles that formed the solar system have evolved to more than 4500 species today. Previous work from Carnegie’s Bob Hazen demonstrated that up to two thirds of the known types […]

August 11th, 2012 Riffin From protozoans to mammals, evolution has created more and more complex structures and better-adapted organisms. This is all the more astonishing as most genetic mutations are deleterious. Especially in small asexual populations that do not recombine their genes, unfavourable mutations can accumulate. This process is known as Muller’s ratchet in evolutionary biology. The ratchet, proposed […]

August 7th, 2012 riffin Seawater circulation pumps hydrogen and boron into the oceanic plates that make up the seafloor, and some of this seawater remains trapped as the plates descend into the mantle at areas called subduction zones. By analyzing samples of submarine volcanic glass near one of these areas, scientists found unexpected changes in isotopes of hydrogen and […]

August 6th, 2012 riffin Karl Bates and his colleagues in the palaeontology and biomechanics research group have reconstructed the bodies of five dinosaurs, two T. rex (Stan at the Manchester Museum and the Museum of the Rockies cast MOR555), an Acrocanthosaurus atokensis, a Strutiomimum sedens and an Edmontosaurus annectens. The team, whose findings are published in the Public Library of Science journal PLoS ONE today (19th February […]

August 6th, 2012 riffin No matter how well adapted an animal may be, it can spell evolutionary doom to have feathers or even shells that become coveted by human beings. Take the nautilus, a creature that pulled easily through the asteroid impact that wiped out the dinosaurs. It now hangs on the brink of extinction thanks to the misfortune […]

August 5th, 2012 riffin An unusual breed of dinosaur that was the size of a chicken, ran on two legs and scoured the ancient forest floor for termites is the smallest dinosaur species found in North America, according to a University of Calgary researcher who analyzed bones found during the excavation of an ancient bone bed near Red Deer, […]

August 5th, 2012 riffin We’ve all heard this story: the Late Cretaceous of Asia and North America-about 65 million years ago-was dominated by several large-headed, bipedal predatory dinosaurs like Tyrannosaurus rex and Tarbosaurus that had tiny arms. But a decade of new fossil discoveries that have more than doubled the number of known tyrannosaur species has changed this tale. Older and smaller tyrannosaurs […]

August 4th, 2012 riffin Research led by scientists at the American Museum of Natural History shows that ammonites-an extinct type of shelled mollusk that’s closely related to modern-day nautiluses and squids-made homes in the unique environments surrounding methane seeps in the seaway that once covered America’s Great Plains. The findings, published online this week in the journalGeology, provide new […]
