WFS News: Tooth Loss Precedes the Origin of Baleen in Whales

@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.

WFS News: Synthetic microorganisms and study of evolution

@ 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 […]

WFS News: Climate Change and the Geophysical Underpinnings of Species Diversity

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Conserving the Stage: Climate Change and the Geophysical Underpinnings of Species Diversity Conservationists have proposed methods for adapting to climate change that assume species distributions are primarily explained by climate variables. 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

@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 […]

WFS News: Plant fossils provide new insight into the uplift history of SE Tibet

@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 […]

WFS News: Early African Fossils Elucidate the Origin of Embrithopod Mammals

@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, […]
