In the modern global climate, higher levels of carbon dioxide (CO2) in the atmosphere are associated with rising ocean temperatures. But the seas were not always so sensitive to this CO2 “forcing,” according to a new report. Around 5 to 13 million years ago, oceans were warmer than they are today — even though atmospheric […]

No Comments »Fossil scars capture dinosaur headbutts
January 6th, 2013 Riffin With domed heads and thick, bony skull protuberances, pachycephalosaurids are well known by seven-year-olds and palaeontologists alike. The dinosaurs are thought to have used their thick domes to headbutt each other, perhaps as part of courtship behaviour. But whereas children recreating these vicious displays simply ram plastic models of the animals together in a straight […]

January 5th, 2013 Riffin Recently, the complete genome of a glaucophyte alga (Cyanophora paradoxa) has been unraveled by an international consortium led by Dr. Debashish Bhattacharya from Rutgers University (USA). From the University of Freiburg, Dr. Stefan Rensing and Aikaterini Symeonidi (Faculty of Biology), contributed to the analysis of the genome by performing classification and phylogenomic analyses of the […]

January 4th, 2013 Riffin The asteroid collision widely thought to have killed the dinosaurs also led to extreme devastation among snake and lizard species, according to new research — including the extinction of a newly identified lizard Yale and Harvard scientists have named Obamadon gracilis. “The asteroid event is typically thought of as affecting the dinosaurs primarily,” said Nicholas […]

January 3rd, 2013 Riffin An international team of scientists, including PhD student Stephan Lautenschlager and Dr Emily Rayfield of the University of Bristol, found that the senses of smell, hearing and balance were well developed in therizinosaurs and might have affected or benefited from an enlarged forebrain. These findings came as a surprise to the researchers as exceptional sensory […]

December 28th, 2012 Riffin In the period just before they went extinct, the American lions and saber-toothed cats that roamed North America in the late Pleistocene were living well off the fat of the land. That is the conclusion of the latest study of the microscopic wear patterns on the teeth of these great cats recovered from the La […]

December 27th, 2012 Riffin Ancient multicellular fossils long thought to be ancestors of early marine life are remnants of land-dwelling lichen or other microbial colonies, says University of Oregon scientist Gregory J. Retallack, who has been studying fossil soils of South Australia. Ediacaran (pronounced EDI-akran) fossils date to 542-635 million years ago. They’ve been considered fossil jellyfish, worms and […]

December 26th, 2012 Riffin A new mosasaur species discovered in Hungary is the first known example of this group of scaled reptiles to have lived in freshwater river environments similar to modern freshwater dolphins. The research is published Dec. 19 in the open-access journal PLOS ONE by Laszlo Makadi from the Hungarian Natural History Museum, Hungary and colleagues from […]

December 24th, 2012 Riffin A research team led by biogeochemists at the University of California, Riverside has tested a popular hypothesis in paleo-ocean chemistry, and proved it false. The fossil record indicates that eukaryotes — single-celled and multicellular organisms with more complex cellular structures compared to prokaryotes, such as bacteria — show limited morphological and functional diversity before 800-600 […]

December 23rd, 2012 Riffin Dinosaurs were not only the largest animals to roam the Earth — they also had a greater number of larger species compared to all other back-boned animals — scientists suggest in a new paper published in the journal PLOS ONE. The researchers, from Queen Mary, University of London, compared the size of the femur bone of […]
