A bipedal, German shepherd–sized dinosaur may have had soft tissues in its nasal cavity that cooled the blood flowing to its brain, a new study suggests. The plant-eating Stegoceras validum belongs to a group called pachycephalosaurs (which in Greek means “thick-headed lizards”). CT scans of one particularly well preserved skull revealed delicate scrolls of bones […]

Hualianceratops wucaiwanensis: New Species of Ceratopsian Dinosaur Discovered in China
December 13th, 2015 
Riffin An international team of paleontologists has discovered a new species of hornless ceratopsian dinosaur, called Hualianceratops wucaiwanensis, in China. This new dinosaur was a distant cousin of the famed ceratopsian dinosaur Triceratops and lived early in the Late Jurassic period, roughly 160 million years ago. According to a study published this week in the journal […]
Extinct 3-horned palaeomerycid ruminant found in Spain
December 8th, 2015 Riffin The extinct three-horned palaeomerycid ruminant, Xenokeryx amidalae, found in Spain, may be from the same clade as giraffes, according to a study published December 2, 2015 in the open-access journal PLOS ONE by Israel M. Sánchez from the Museo Nacional de Ciencias Naturales-CSIC, Madrid, Spain, and colleagues. Palaeomerycids, now extinct, were strange three-horned Eurasian Miocene […]

December 6th, 2015 Riffin The role volcanic activity played in dinosaur extinction events in Earth’s early history is likely to have been much less severe than previously thought, according to a study led by the University of Leeds. Asteroid impacts and long-lasting volcanic eruptions called continental flood basalts — the two most commonly cited possible causes of mass extinction […]
Original blood vessels in hadrosaur fossil
December 3rd, 2015 Riffin Researchers from North Carolina State University have confirmed that blood vessel-like structures found in an 80 million-year-old hadrosaur fossil are original to the animal, and not biofilm or other contaminants. Their findings add to the growing body of evidence that structures like blood vessels and cells can persist over millions of years, and the data […]

December 2nd, 2015 Riffin The sweet, juicy peaches we love today might have been a popular snack long before modern humans arrived on the scene.Scientists have found eight well-preserved fossilized peach endocarps, or pits, in southwest China dating back more than two and a half million years. Despite their age, the fossils appear nearly identical to modern peach pits. […]

November 30th, 2015 Riffin Fresh analysis of a reptile fossil is helping scientists solve an evolutionary puzzle — how snakes lost their limbs. The 90 million-year-old skull is giving researchers vital clues about how snakes evolved. Comparisons between CT scans of the fossil and modern reptiles indicate that snakes lost their legs when their ancestors evolved to live and […]
Egg Shell porosity and Nesting in Dinosaurs
November 29th, 2015 Riffin Extinct archosaurs’ eggshell porosity may be used as a proxy for predicting covered or exposed nest types, according to a study published November 25, 2015 in the open-access journal PLOS ONE by Kohei Tanaka from the University of Calgary and colleagues. Knowledge about dinosaur nests may provide insight into the evolution of nesting and reproductive […]
