Comparative descriptions of the cranial morphology in living and extinct turtles are presented in this paper. Descriptions are arranged by bone rather than by taxon and attempt to document the types and degrees of differences in cranial structures within the Testudines, emphasizing features of systematic interest. Developmental information is also included. 273 figures supplement the […]

August 31st, 2012 riffin An enormous prehistoric bird, which might have resembled a very big ostrich, lived alongside dinosaurs around 83 million years ago, according to new research. The bird, called Samrukia nessovi after the mythical Kazakh Phoenix, lived in what is now Kazakhstan. It is described in the latest Royal Society Biology Letters. The discovery confirms “that big birds were living […]

August 30th, 2012 riffin Sinocalliopteryx (meaning ‘Chinese beautiful feather’) is a genus of carnivorous ciomsognathid theropod dinisaurs from the lower Cretaceous Yixian Formation if China (Jianshangou Beds, dating to 124.6 Ma). While similar to the related Huaxiagnathus, Sinocalliopteryx were larger, and at 2.37 meters (7.78 ft) in length, includes the largest known compsognathid specimen. Sinocalliopteryx was a bipedal predator. The preserved length of the holotype specimen is 237 […]

August 30th, 2012 riffin A rare dino-fossil has led researchers at the University of Alberta to a discovery they say may forever change the way the Cretaceous period is looked at. After unearthing two well preserved fossils from China’s Liaoning province, researchers have been able to get a more clear grasp of the eating habits of Sinocalliopteryx, a feathered, […]

August 29th, 2012 riffin A new model for primate origins is presented in Zoologica Scripta, published by the Norwegian Academy of Science and Letters and The Royal Swedish Academy of Sciences. The paper argues that the distributions of the major primate groups are correlated with Mesozoic tectonic features and that their respective ranges are congruent with each evolving locally from […]

August 29th, 2012 riffin An international team of scientists has discovered the oldest record of arthropods — invertebrate animals that include insects, arachnids, and crustaceans — preserved in amber. The specimens, one fly and two mites found in millimeter-scale droplets of amber from northeastern Italy, are about 100 million years older than any other amber arthropod ever collected. The […]

August 28th, 2012 riffin A new look at a fossil mammal with powerful front legs for digging is clearing up questions about the origin of a group of strange and scaly modern-day creatures called pangolins. First excavated in Mongolia in the 1970s, the fossil sat in storage for decades until researchers for the Russian Academy of Sciences rediscovered and […]

August 28th, 2012 riffin A team of paleontologists, including a University of Pennsylvania doctoral candidate, has described a new species of dinosaur based upon an incomplete skeleton found in western New Mexico. The new species,Jeyawati rugoculus, comes from rocks that preserve a swampy forest ecosystem that thrived near the shore of a vast inland sea 91 million years ago. […]

August 27th, 2012 riffin A new prehistoric croc sporting an odd head “shield” has been found in Morocco, according to a study published . Dubbed ShieldCroc, the animal’s head appendage was surrounded by blood vessels and covered with a sheath like those seen in frilled dinosaurs, including Triceratops. At 30 to 35 feet (9 to 11 meters) long, the […]
Cause of Dinosaur Boom relating to rise of Rocky mountain
August 26th, 2012 riffin The evolution of new dinosaur species may have surged due to the rise of the Rocky Mountains and the emergence of a prehistoric inner sea in North America, researchers say. Duck-billed and horned dinosaurs flourished in North America, reaching a peak about 75 million years ago, a time known as the Campanian. For instance, one Campanian […]
