@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 […]

Riffin 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 […]

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 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 […]

The key idea is to use the understanding of species-climate relationships to map corridors and to identify […]
WFS News: Fossil of Oldest Flowering Tree in North America Discovered
October 1st, 2018 Riffin @WFS,World Fossil Society, Riffin T Sajeev,Russel T Sajeev During the late Cretaceous period, northeastern Utah was home to pterosaurs, duck-billed dinosaurs and fearsome therizinosaurs with claws that would put Edward Scissorhands to shame. Now, add to that list giant flowering trees. A fossil log found in the Mancos Shale of Utah reveals that huge angiosperms were part […]

July 17th, 2018 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The Tibetan Plateau, the highest and largest plateau in the world, is well known as ‘The Third Pole’. Tibet has also been called ‘Asia’s water tower’ because so many of Asia’s major rivers such as the Ganges, Indus, Tsangpo/Brahmaputra, Mekong, Yellow and Yangse rivers originate there. Despite its […]
