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: Ponomarenkia belmonthensis,300 MYO beetle

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev He’s Australian, around half a centimetre long, fairly nondescript, 300 million years old, and he’s currently causing astonishment among both entomologists and palaeontologists. The discovery of a beetle from the late Permian period, when even the dinosaurs had not yet appeared on the scene, is throwing a completely […]

WFS News: Albertavenator curriei named in honor of renowned paleontologist

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists from the Royal Ontario Museum (ROM) and the Philip J Currie Dinosaur Museum have identified and named a new species of dinosaur in honour of renowned Canadian palaeontologist Dr. Philip J. Currie. Albertavenator curriei, meaning “Currie’s Alberta hunter.” It stalked Alberta, Canada, about 71 million years ago […]

WFS News: Can satellites be used as an early warning system for landslides?

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Researchers are using satellite data to accurately map the movement of the earth before a landslide in a bid to develop a life-saving early warning system. The team from Newcastle University (UK), Chengdu University of Technology, Tongji University, China Academy of Space Technology and Wuhan University (China) have […]

WFS News:Falling sea level caused volcanoes to overflow

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Climate evolution shows some regularities, which can be traced throughout long periods of earth’s history. One of them is that the global average temperature and the carbon dioxide concentration in the atmosphere usually go hand-in-hand. To put it simple: If the temperatures decline, the CO2values also decrease and […]

WFS News:Rapid rise of the Mesozoic sea dragons

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev In the Mesozoic, the time of the dinosaurs, from 252 to 66 million years ago, marine reptiles such as ichthyosaurs and plesiosaurs were top predators in the oceans. But their origins and early rise to dominance have been somewhat mysterious. New research published this week in the journal […]

Just how old are animals?

The origin of animals was one of the most important events in the history of Earth. Beautifully preserved fossil embryos suggest that our oldest ancestors might have existed a little more than half a billion years ago.

Paleozoic echinoderm hangover: Waking up in the Triassic

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The end-Paleozoic witnessed the most devastating mass extinction in Earth’s history so far, killing the majority of species and profoundly shaping the evolutionary history of the survivors. Echinoderms are among the marine invertebrates that suffered the most severe losses at the end-Permian extinction. At least that was the […]
