@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 […]

July 25th, 2017
Riffin @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 […]

July 7th, 2017
Riffin @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
June 26th, 2017
Riffin @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 […]

Paleozoic echinoderm hangover: Waking up in the Triassic
March 17th, 2017
Riffin @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 […]
