@WFS,World Fossil Society, Athira, Riffin T Sajeev,Russel T Sajeev One of the biggest crises in Earth’s history, marked by a significant shift in shellfish, saw the widespread replacement of brachiopods, often referred to as ‘lamp shells’, with bivalve species such as oysters and clams. This happened as a result of the devastating end-Permian mass extinction, which effectively […]

April 11th, 2022 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev,Athira Scientists say that the perfectly preserved leg of a Thescelosaurus dinosaur, complete with scaly skin, can be dated back to the mass extinction event because of the presence of debris from the impact, the BBC said. It is widely believed that when the 7.5 mile-wide asteroid, approximately the size of […]

July 27th, 2017 Riffin @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
May 11th, 2017 Riffin @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 […]

July 21st, 2016 Riffin 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 […]

June 13th, 2016 Riffin 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 […]

May 28th, 2016 Riffin 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
October 24th, 2015 Riffin 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 […]

May 2nd, 2013 Riffin 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 […]
