@WFS,World Fossil Society, Athira, Riffin T Sajeev,Russel T Sajeev Fossil evidence reveals that the long necks of the ancient marine reptiles, Tanystropheus, made them vulnerable to predators. The study found bite marks on the necks of the fossils, providing the first direct proof of this long-suspected evolutionary disadvantage despite their survival success over a span […]

August 26th, 2022 Riffin @WFS,World Fossil Society,Athira,Riffin T Sajeev,Russel T Sajeev Scientists have long debated the origins of teeth. Did they evolve from body scales that migrated into the mouths of ancient vertebrates and became adapted for eating — an idea known as the “outside-in” hypothesis? Or did they evolve independent of scales, originating deep within the oral cavity […]

March 8th, 2020 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev About 75 million years ago, a nest of plant-eating dinosaurs called Hypacrosaurus stebingeri died in what’s now Montana. Their fossils were found in the 1980s, and now an international team of scientists has presented evidence that the old bones contain traces of genetic material. The paper published in National Science […]

February 11th, 2019 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A 52-million-year fossil of a “perching bird” has been found in Wyoming with its feathers still attached, a discovery that “no one’s ever seen before.” Also known as passerines, the perching bird was discovered in Fossil Lake, WY. Passerines are well-known for eating seeds, as most modern-day birds do and […]
Earth’s oldest animals formed complex communities
September 19th, 2018 Riffin A new analysis is shedding light on Earth’s first macroscopic animals: the 570-million-year-old, enigmatic Ediacara biota. Ediacaran fossils have a slightly bizarre appearance not shared by any modern animal groups. For decades, researchers believed these enigmatic fossils were ecologically simple. However, borrowing a method from modern ecology — fitting species to relative abundance distributions — […]

August 29th, 2018 Riffin An international team of researchers discovered a new species of dinosaur, Xiyunykus pengi, during an expedition to Xinjiang, China. The discovery is the latest stemming from a partnership between the George Washington University and the Chinese Academy of Sciences. The findings were published today in Current Biology along with the description of a second new […]

July 1st, 2018 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Long before rhinoceros, giraffes, hippos, and antelopes roamed the African savannah, a group of large and highly specialized mammals known as embrithopods inhabited the continent. The most well known is Arsinoitherium, an animal that looked much like a rhinoceros but was in fact more closely related to elephants, […]

May 10th, 2018 Riffin @WFS,World Fosssil Society,Riffin T Sajeev,Russel T Sajeev Spherical, isolated carbonate concretions occur throughout the world in marine argillaceous sedimentary rocks of widely varying geological ages. These concretions are characteristically highly enriched in CaCO3compared to the surrounding sedimentary rock matrices and are typically separated from these rock matrices by sharp boundaries1,2,3. These sharp boundaries mean that […]
WFS News: Treasure trove of highly detailed fossils uncovered
