WFS News: T. rex fossil leads researchers to new species of shark

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev T. rex fossil leads researchers to new species of shark Scientists examining rock left over from the discovery of a fossilized Tyrannosaurus rex recently came across a surprise: shark teeth. The huge meat-eating dinosaur, the remains of which were extricated in the 1990s, was not killed by a shark. But, scientists said on […]

WFS News: Surface exposure dating with cosmogenic nuclides

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Surface exposure dating with cosmogenic nuclides  SUSAN IVY-OCHS & FLORIAN KOBER Eiszeitalter und Gegenwart Quaternary Science Journal,57/1–2,157–189,Hannover 2008 Abstract: In the last decades surface exposure dating using cosmogenic nuclides has emerged as a powerful tool in Quaternary geochronology and landscape evolution studies. Cosmogenic nuclides are produced in rocks and […]

WFS News: An unexpected noncarpellate epigynous flower from the Jurassic of China

@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

@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: 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: Oldest skeleton of a fossil flying squirrel

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The oldest flying squirrel fossil ever found has unearthed new insight on the origin and evolution of these airborne animals. Writing in the open-access journal eLife, researchers from the Institut Català de Paleontologia Miquel Crusafont (ICP) in Barcelona, Spain, described the 11.6-million-year-old fossil, which was discovered in Can Mata […]
