@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev CHAMPAIGN, Ill. — Roughly 115 million years ago, when the ancient supercontinent Gondwana was breaking apart, a mushroom fell into a river and began an improbable journey. Its ultimate fate as a mineralized fossil preserved in limestone in northeast Brazil makes it a scientific wonder, scientists report in […]

Cosmogenic nuclides are produced in rocks and […]

January 18th, 2019 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Despite the importance of, the great interest in and intensive effort spent on investigating angiosperms, a controversy remains as to when and how this group came into existence. Since the time of Darwin, some scholars have proposed that angiosperms existed before the Cretaceous (Smith et al., 2010; Clarke et […]
WFS News: Trilobite ancestral range in the southern hemisphere reconstructed
January 15th, 2019 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The first appearance of trilobites in the fossil record dates to 521 million years ago in the oceans of the Cambrian Period, when the continents were still inhospitable to most life forms. Few groups of animals adapted as successfully as trilobites, which were arthropods that lived on the […]

WFS News: Introduction to dating glacial sediments
January 12th, 2019 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Many methods of dating glacial sediments As glacial geologists, some of the biggest questions that we’d like to answer are not only how large former ice sheets were, but also how fast did the recede and how quickly did they thin? This information is vital for numerical models, […]
WFS News: Tooth Loss Precedes the Origin of Baleen in Whales
December 1st, 2018 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Rivaling the evolution of feathers in dinosaurs, one of the most extraordinary transformations in the history of life was the evolution of baleen — rows of flexible hair-like plates that blue whales, humpbacks and other marine mammals use to filter relatively tiny prey from gulps of ocean water. […]

November 25th, 2018 Riffin Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench. The observations from the deepest ocean trench in the world have important implications for the global water cycle, according to researchers in […]

November 21st, 2018 Riffin Analysis of ancient DNA of a mysterious extinct monkey named Xenothrix — which displays bizarre body characteristics very different to any living monkey — has revealed that it was in fact most closely related to South America’s titi monkeys (Callicebinae). Having made their way overwater to Jamaica, probably on floating vegetation, their bones reveal they […]
