@WFS,World Fossil Society, Athira, Riffin T Sajeev, Russel T Sajeev Palaeontologists at University College Cork (UCC) in Ireland have discovered that some feathered dinosaurs had scaly skin like reptiles today, thus shedding new light on the evolutionary transition from scales to feathers. The researchers studied a new specimen of the feathered dinosaur Psittacosaurus from the early Cretaceous […]

August 9th, 2020 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Present knowledge of Late Triassic tetrapod evolution, including the rise of dinosaurs, relies heavily on the fossil-rich continental deposits of South America, their precise depositional histories and correlations. We report on an extended succession of the Ischigualasto Formation exposed in the Hoyada del Cerro Las Lajas (La Rioja, […]

November 18th, 2018 Riffin Islands have been vital laboratories for advancing evolutionary theory since the pioneering work of Charles Darwin and Alfred Russel Wallace in the 19th century. Now, a new paper appearing in PLOS ONE from an international team of investigators describes two new fossil relatives of marsupials that shed light on how a unique island ecosystem evolved […]

November 1st, 2018 Riffin @ WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists at Scripps Research and their collaborators have created microorganisms that may recapitulate key features of organisms thought to have lived billions of years ago, allowing them to explore questions about how life evolved from inanimate molecules to single-celled organisms to the complex, multicellular lifeforms we see […]

September 4th, 2018 Riffin Compared with the rest of the animal kingdom, mammals have the biggest brains and produce some of the smallest litters of offspring. A newly described fossil of an extinct mammal relative — and her 38 babies — is among the best evidence that a key development in the evolution of mammals was trading brood power […]

January 3rd, 2018 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Paleontologists at the University of Alberta have developed a new theory to explain why the ancient ancestors of dinosaurs stopped moving about on all fours and rose up on just their two hind legs. Bipedalism in dinosaurs was inherited from ancient and much smaller proto-dinosaurs. The trick to […]

June 22nd, 2017 Riffin The fossil of an early snake-like animal — called Lethiscus stocki — has kept its evolutionary secrets for the last 340-million years. Now, an international team of researchers has revealed new insights into the ancient Scottish fossil that dramatically challenge our understanding of the early evolution of tetrapods, or four-limbed animals with backbones.
