WFS News: Whether sills caused mass extinction?

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A study by a researcher in the Syracuse University College of Arts and Sciences offers new clues to what may have triggered the world’s most catastrophic extinction, nearly 252 million years ago. James Muirhead, a research associate in the Department of Earth Sciences, is the co-author of an […]

WFS News: Birgeria americana,Large-mouthed fish was top predator after mass extinction

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The most catastrophic mass extinction on Earth took place about 252 million years ago — at the boundary between the Permian and Triassic geological periods. Up to 90 percent of the marine species of that time were annihilated. Worldwide biodiversity then recovered in several phases throughout a period […]

WFS News: Sponges Ruled the World After Second-Largest Mass Extinction

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Sponges may be simple creatures, but they basically ruled the world some 445 million years ago, after the Ordovician mass extinction, a new study finds. Roughly 85 percent of all species died in the Ordovician mass extinction, the first of the world’s five known mass extinctions. (The other […]

WFS News : Aftermath of a mass extinction

A new study of fossil fishes from Middle Triassic sediments on the shores of Lake Lugano provides new insights into the recovery of biodiversity following the great mass extinction event at the Permo-Triassic boundary 240 million years ago. The largest episode of mass extinction in the history of the Earth, which led to the demise […]

WFS News: Last dinosaur before mass extinction discovered

A team of scientists has discovered the youngest dinosaur preserved in the fossil record before the catastrophic meteor impact 65 million years ago. The finding indicates that dinosaurs did not go extinct prior to the impact and provides further evidence as to whether the impact was in fact the cause of their extinction. Researchers from […]

WFS News: Sclerocormus parviceps reveal rapid evolution after mass extinction ?

Two hundred and fifty million years ago, life on earth was in a tail-spin–climate change, volcanic eruptions, and rising sea levels contributed to a mass extinction that makes the death of the dinosaurs look like child’s play. Marine life got hit hardest–96% of all marine species went extinct. For a long time, scientists believed that […]

Mass extinction led to many new species of bony fish

With over 30,000 species worldwide, the ray fins are currently the largest group of fish. These bony fish were not always as numerous, however. Losses of other fish species, such as cartilaginous fish, helped them to spread successfully. As paleontologists from the University of Zurich together with international researchers reveal, a series of serious extinction […]

Weird Dino Ancestors Boomed After Mass Extinction

Dinosaurs — or at least their ancestors — may have gotten an earlier start than once believed. Bizarre four-legged creatures that resembled demonic dogs and predated dinosaurs branched out shortly after an extinction that wiped out most of life on land, according to a new study. Some of these creatures were the direct ancestors of […]
