WFS News:Description of climate-envelope models

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Climate-envelope models attempt to capture the climatic conditions that constrain the potential niche of a species, and use them to predict the probability of occurrence of species in an area. There are many different types of climate-envelope models [1], distinguished among other things by the type of data […]

Plate tectonics may have been active on Earth since its origin

A new study suggests that plate tectonics — a scientific theory that divides Earth into large chunks of crust that move slowly over hot viscous mantle rock — could have been active from the planet’s very beginning. The new findings defy previous beliefs that tectonic plates were developed over the course of billions of years. […]

WFS News: Fossil of Oldest Flowering Tree in North America Discovered

@WFS,World Fossil Society, Riffin T Sajeev,Russel T Sajeev During the late Cretaceous period, northeastern Utah was home to pterosaurs, duck-billed dinosaurs and fearsome therizinosaurs with claws that would put Edward Scissorhands to shame. Now, add to that list giant flowering trees. A fossil log found in the Mancos Shale of Utah reveals that huge angiosperms were part […]

Fat from 558 million years ago reveals earliest known animal

Scientists from The Australian National University (ANU) and overseas have discovered molecules of fat in an ancient fossil to reveal the earliest confirmed animal in the geological record that lived on Earth 558 million years ago. The strange creature called Dickinsonia, which grew up to 1.4 metres in length and was oval shaped with rib-like […]

WFS News: Ancient ‘Alien’ Wasp Hijacked Fly Pupae, Ate the Flies Inside

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Fossilized fly pupae are about as exciting to look at as a handful of dingy, stale Rice Krispies. But despite their humdrum appearance, fossil pupae can hold fascinating secrets inside; in some cases, they preserve deadly examples of insect parasitism. Scientists recently investigated hundreds of fossil pupae — […]

Earth’s oldest animals formed complex communities

A new analysis is shedding light on Earth’s first macroscopic animals: the 570-million-year-old, enigmatic Ediacara biota. Ediacaran fossils have a slightly bizarre appearance not shared by any modern animal groups. For decades, researchers believed these enigmatic fossils were ecologically simple. However, borrowing a method from modern ecology — fitting species to relative abundance distributions — […]

Ancient bird bones redate human activity in Madagascar by 6,000 years

Analysis of bones, from what was once the world’s largest bird, has revealed that humans arrived on the tropical island of Madagascar more than 6,000 years earlier than previously thought — according to a study published today, 12 September 2018, in the journal Science Advances. A team of scientists led by international conservation charity ZSL […]

Geologists reveal ancient connection between England and France

The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research. Scientists have for centuries believed that England, Wales and Scotland were created by the merger of Avalonia and Laurentia more than 400 million years ago. However, geologists based at the University of Plymouth now […]

Global warming: Worrying lessons from the past

Fifty-six million years ago, Earth experienced an exceptional episode of global warming. In a very short time on a geological scale, within 10,000 to 20,000 years, the average temperature increased by 5 to 8 degrees, only returning to its original level a few hundred thousand years later. Based on the analysis of sediments from the […]

Ancient farmers profoundly changed Earth’s climate!!!

Millennia ago, ancient farmers cleared land to plant wheat and maize, potatoes and squash. They flooded fields to grow rice. They began to raise livestock. And unknowingly, they may have been fundamentally altering the climate of Earth. A study published in the journal Scientific Reports provides new evidence that ancient farming practices led to a […]
