Tetradactyl Footprints of an Unknown Affinity Theropod Dinosaur from the Upper Jurassic of Morocco
November 15th, 2012
riffin In this work the study surface where the footprints were registered was examined carefully. The study surface may or may be not the tracking surface (the surface where the dinosaur stepped) . All the surfaces with true footprints in Iouaridène syncline have been found in the hard layers (red siliceous levels) with mud cracks . The undertracks […]
Greenland Rocks Provide Evidence of Earth Formation Process
November 12th, 2012
riffin Rocks dating back 3.4 billion years from south-west Greenland’s Isua mountain range have yielded valuable information about the structure of Earth during its earliest stages of development. In these rocks, which witnessed the first billion years of Earth’s history, a French-Danish team led by researchers from the ‘Magmas and Volcanoes’ Laboratory (CNRS / Université Blaise […]
New Computational Method for Timing the Tree of Life
November 11th, 2012
riffin With its deeply embedded roots, sturdy trunk and dense profusion of branches, the Tree of Life is a structure of nearly unfathomable complexity and beauty. While major strides have been made to establish the evolutionary hierarchy encompassing every living species, the project is still in its infancy. At Arizona State University’s Biodesign Institute, Sudhir Kumar […]
Xenoceratops: Canada’s Newest Horned Dinosaur
November 10th, 2012
Riffin Scientists have named a new species of horned dinosaur (ceratopsian) from Alberta, Canada. Xenoceratops foremostensis (Zee-NO-Sare-ah-tops) was identified from fossils originally collected in 1958. Approximately 20 feet long and weighing more than 2 tons, the newly identified plant-eating dinosaur represents the oldest known large-bodied horned dinosaur from Canada. Research describing the new species is published in the […]
Mohorovičić Discontinuity
November 6th, 2012
riffin What is the Mohorovičić Discontinuity? The Mohorovicic Discontinuity, or “Moho”, is the boundary between the crust and the mantle. The red line in the drawing below shows its location. In geology the word “discontinuity” is used for a surface at which seismic waves change velocity. One of these surfaces exists at an average depth of […]
Exhaustive Family Tree for Birds Shows Recent, Rapid Diversification
November 1st, 2012
riffin A Yale-led scientific team has produced the most comprehensive family tree for birds to date, connecting all living bird species — nearly 10,000 in total — and revealing surprising new details about their evolutionary history and its geographic context. Analysis of the family tree shows when and where birds diversified — and that birds’ diversification […]
CT scans reveal that dinosaurs were airheads
October 31st, 2012
Riffin 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 […]
Huge Deposit of Jurassic Turtle Remains Found in China ?
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. […]
