In their article for Lithosphere on 12 March, authors Kristin Morell and colleagues write, “The ∼700-km-long ‘central seismic gap’ is the most prominent segment of the Himalayan front not to have ruptured in a major earthquake during the last 200-500 years. This prolonged seismic quiescence has led to the proposition that this region, with a […]

WFS: Ariyalur Fossils ( Arctostrea )
May 2nd, 2015 
Riffin WFS: Ariyalur Fossils ( Arctostrea ): This upper Cretaceous oyster is characterized by long and curved valves. Stout ribs cross the upper valve. The sample is obtained from Ariyalur/Dalmiapuram area. samples collected by Riffin T Sajeev and Russel T Sajeev from World Fossil society. The Rastellum genus of oysters lived between 161 to 65 million […]
Brachiopod shell shows sign of evolution
May 1st, 2015 Riffin Researchers of Ludwig-Maximilians-Universitaet (LMU) in Munich have carried out the first detailed study of the molecular mechanisms responsible for formation of the brachiopod shell. Comparison with shell synthesis in other groups reveals the deep evolutionary roots of the process. Brachiopods (lamp shells) are marine invertebrates, which were a highly successful and widespread group in the […]

‘platypus’ dinosaur: Vegetarian relative of T. rex
April 28th, 2015 Riffin Although closely related to the notorious carnivore Tyrannosaurus rex, a new lineage of dinosaur discovered in Chile is proving to be an evolutionary jigsaw puzzle, as it preferred to graze upon plants. Palaeontologists are referring to Chilesaurus diegosuarezi as a ‘platypus’ dinosaur because of its bizarre combination of characters that resemble different dinosaur groups. For […]
mammoths back to life !
April 25th, 2015 Riffin An international team of researchers has sequenced the nearly complete genome of two Siberian woolly mammoths — revealing the most complete picture to date — including new information about the species’ evolutionary history and the conditions that led to its mass extinction at the end of the Ice Age. “This discovery means that recreating extinct […]

April 23rd, 2015 Riffin Abstract Conclusive evidence for sexual dimorphism in non-avian dinosaurs has been elusive. Here it is shown that dimorphism in the shape of the dermal plates of Stegosaurus mjosi (Upper Jurassic, western USA) does not result from non-sex-related individual, interspecific, or ontogenetic variation and is most likely a sexually dimorphic feature. One morph possessed wide, oval […]
Oldest fossils controversy resolved
April 22nd, 2015 Riffin New analysis of world-famous 3.46 billion-year-old rocks by researchers from the University of Bristol, the University of Oxford and UWA (the University of Western Australia) is set to finally resolve a long running evolutionary controversy. The new research, published this week in Proceedings of the National Academy of Sciences, shows that structures once thought to […]
WFS : Ariyalur Fossils : Rastellum Carinatum
April 16th, 2015 Riffin Rastellum (Arctostrea) carinatum (Lamarck) This upper Cretaceous oyster is characterized by long and curved valves. Stout ribs cross the upper valve. The sample is obtained from Ariyalur/Dalmiapuram area. samples collected by Riffin T Sajeev and Russel T Sajeev from World Fossil society. The Rastellum genus of oysters lived between 161 to 65 million years ago […]
A new birth story for mosasaurs discovered.
April 15th, 2015 Riffin They weren’t in the delivery room, but researchers at Yale University and the University of Toronto have discovered a new birth story for a gigantic marine lizard that once roamed the oceans. Thanks to recently identified specimens at the Yale Peabody Museum of Natural History, paleontologists now believe that mighty mosasaurs — which could grow […]
