WFS News: Detection of lost calamus challenges identity of isolated Archaeopteryx feather

@WFS,World Fossil Society, Riffin T Sajeev,Russel T Sajeev Abstract Thomas G. Kaye,  Michael Pittman,  Gerald Mayr,  Daniela Schwarz &  Xing Xu  Scientific Reports volume 9, Article number: 1182 (2019) In 1862, a fossil feather from the Solnhofen quarries was described as the holotype of the iconic Archaeopteryx lithographica. The isolated feather’s identification has been problematic, and the fossil was considered either a […]

WFS News: Dinosaur-like archosaur Smok wawelski was crushing bones like a hyena

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Coprolites, or fossil droppings, of the dinosaur-like archosaur Smok wawelski contain lots of chewed-up bone fragments. This led researchers at Uppsala University to conclude that this top predator was exploiting bones for salt and marrow, a behavior often linked to mammals but seldom to archosaurs. Most predatory dinosaurs used their […]

WFS News: Pterosaurs: Fur flies over feathery fossils

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Two exceptionally well preserved fossils give a new picture of the pterosaurs, the flying reptiles that lived at the time of the dinosaurs. Scientists believe the creatures may have had feathers, and looked something like brown bats with fuzzy wings. The surprise discovery suggests feathers evolved not in […]

WFS News: Antarctanax,an Iguana-sized dinosaur from Antarctica

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Antarctica wasn’t always a frozen wasteland — 250 million years ago, it was covered in forests and rivers, and the temperature rarely dipped below freezing. It was also home to diverse wildlife, including early relatives of the dinosaurs. Scientists have just discovered the newest member of that family […]

WFS News: Koreamegops samsiki,The ancient spider had eyes that shone in the dark

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev IF YOU COULD time-travel to Korea 110 million years ago, you’d see an eerie spectacle if you walked out at night with a flashlight: Each sweep of your beam would make the landscape sparkle as innumerable spider eyes glinted in the dark. In a new study in the Journal of Systematic Paleontology, […]

WFS News: What’s the World’s Largest Dinosaur?

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The battle for the title of world’s largest dinosaur is complicated. Here’s why: Paleontologists rarely discover an entire skeleton. They’re more likely to uncover bone fragments and then try to estimate a profile of height and weight. Moreover, there are three categories for largest dinosaur on record: the […]

WFS News: Palaeocene–Eocene Thermal Maximum prolonged by fossil carbon oxidation

WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev  Palaeocene–Eocene Thermal Maximum prolonged by fossil carbon oxidation A rapid rise in temperature on ancient Earth triggered a climate response that may have prolonged the warming for many thousands of years, according to scientists. Their study, published online in Nature Geoscience, provides new evidence of a climate feedback that […]

WFS News: Eretmorhipis carrolldongi,Early Triassic marine reptile

@ WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev No animal alive today looks quite like a duckbilled platypus, but about 250 million years ago something very similar swam the shallow seas in what is now China, finding prey by touch with a cartilaginous bill. The newly discovered marine reptile Eretmorhipis carrolldongi from the lower Triassic period is […]

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: World’s oldest fossil mushroom

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev CHAMPAIGN, Ill. — Roughly 115 million years ago, when the ancient supercontinent Gondwana was breaking apart, a mushroom fell into a river and began an improbable journey. Its ultimate fate as a mineralized fossil preserved in limestone in northeast Brazil makes it a scientific wonder, scientists report in […]
