Researchers in Syracuse University’s College of Arts and Sciences are pairing chemical analyses with micropaleontology — the study of tiny fossilized organisms — to better understand how global marine life was affected by a rapid warming event more than 55 million years ago. Their findings are the subject of an article in the journal Paleoceanography. […]

No Comments »Earliest-known lamprey larva fossils discovered
October 15th, 2014 Riffin Few people devote time to pondering the ancient origins of the eel-like lamprey, yet the evolutionary saga of the bloodsucker holds essential clues to the biological roots of humanity. Today, the Proceedings of the National Academy of Sciences published a description of fossilized lamprey larvae that date back to the Lower Cretaceous — at least […]
Physics determined ammonite shell shape
October 11th, 2014 Riffin Ammonites are a group of extinct cephalopod mollusks with ribbed spiral shells. They are exceptionally diverse and well known to fossil lovers. Régis Chirat, researcher at the Laboratoire de Géologie de Lyon: Terre, Planètes et Environnement (CNRS/Université Claude Bernard Lyon 1/ENS de Lyon), and two colleagues from the Mathematical Institute at the University of Oxford […]
How dinosaur arms turned into bird wings
October 7th, 2014 Riffin Although we now appreciate that birds evolved from a branch of the dinosaur family tree, a crucial adaptation for flight has continued to puzzle evolutionary biologists. During the millions of years that elapsed, wrists went from straight to bent and hyperflexible, allowing birds to fold their wings neatly against their bodies when not flying. How […]

October 4th, 2014 Riffin A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 million years ago — nearly 60 million years before skeletal animals appeared during a huge growth spurt of new life on Earth known as the Cambrian Explosion. […]

October 3rd, 2014 Riffin Scientists have uncovered the fossil of a 52-million-year old beetle that likely was able to live alongside ants — preying on their eggs and usurping resources — within the comfort of their nest. The fossil, encased in a piece of amber from India, is the oldest-known example of this kind of social parasitism, known as […]

September 30th, 2014 Riffin About 210 million years ago when the supercontinent of Pangea was starting to break up and dog-sized dinosaurs were hiding from nearly everything, entirely different kinds of reptiles called phytosaurs and rauisuchids were at the top of the food chain. It was widely believed the two top predators didn’t interact much as the former was […]

September 28th, 2014 Riffin Three University of Michigan geologists are participating in an international effort to drill nearly a mile beneath the surface of New Zealand this fall to bring back rock samples from an active fault known to generate major earthquakes. The goal of the Deep Fault Drilling Project is to better understand earthquake processes by sampling the […]

September 27th, 2014 Riffin The most comprehensive family tree of meat-eating dinosaurs ever created is enabling scientists to discover key details of how birds evolved from them. The study, published in the journal Current Biology, shows that the familiar anatomical features of birds — such as feathers, wings and wishbones — all first evolved piecemeal in their dinosaur ancestors […]
New explanation for origin of plate tectonics?
September 23rd, 2014 Riffin The mystery of what kick-started the motion of our earth’s massive tectonic plates across its surface has been explained by researchers at the University of Sydney. “Earth is the only planet in our solar system where the process of plate tectonics occurs,” said Professor Patrice Rey, from the University of Sydney’s School of Geosciences. “The […]
