Study of ESA shows Earth’s changing magnetism

The first set of high-resolution results from ESA’s three-satellite Swarm constellation reveals the most recent changes in the magnetic field that protects our planet. Launched in November 2013, Swarm is providing unprecedented insights into the complex workings of Earth’s magnetic field, which safeguards us from the bombarding cosmic radiation and charged particles. Measurements made over […]

Fossil tracks show how ancient sea reptiles swam

Trackways formed on an ancient seabed have shed new light on how nothosaurs, ancient marine reptiles that lived during the age of the dinosaurs, propelled themselves through water. The evidence is described by a team from Bristol and China in Nature Communications today. During the Mesozoic, 252-66 million years ago, the seas were ruled by […]

New fossil find pinpoints the origin of jaws in vertebrates

Source: University of Cambridge A major fossil discovery in Canada sheds new light on the development of the earliest vertebrates, including the origin of jaws, the first time this feature has been seen so early in the fossil record. A key piece in the puzzle of the evolution of vertebrates has been identified, after the […]

Earth may have underground ‘ocean’ three times that on surface

Source : The Guardian After decades of searching scientists have discovered that a vast reservoir of water, enough to fill the Earth’s oceans three times over, may be trapped hundreds of miles beneath the surface, potentially transforming our understanding of how the planet was formed. The water is locked up in a mineral called ringwoodite […]

5-Million-Year-Old Arctic Fox Ancestor Found in Tibet

Source : Livescience By Tia Ghose, Staff Writer | LiveScience.com The fossilized jawbone and teeth of a 5-million-year-old fox have been unearthed in Tibet. The fox, Vulpes qiuzhudingi, is probably the ancestor of modern Arctic foxes. The discovery, along with several other fossils from cold-loving mammals, buttress the Out of Tibet hypothesis: That iconic ice-age […]

Ancient Elephant Fossil Discovered in New Mexico

Many crazy antics can happen at bachelor parties, but discovering an ancient fossil isn’t usually one of them. Well, that was the case for a group of campers celebrating a bachelor party at a New Mexico state park Monday, who stumbled upon the fossil of a 3-million-year-old elephant-like creature called a stegomastodon. The stag group […]

Earthquakes due to volcanic pressure : A warning signal of Volcanic eruptions

Source: Wiley New research in Geophysical Research Letters examines earthquake swarms caused by mounting volcanic pressure which may signal an imminent eruption. The research team studied Augustine Volcano in Alaska which erupted in 2006 and found that precursory earthquakes were caused by a block in the lava flow. 36 hours before the first magmatic explosions, […]

Baltic amber deposits reveal A new species of flat bug from the genus Aradus preserved in amber

A piece of Eocene Baltic Amber of about 45 million years age contains a well preserved extinct flat bug, which turned out to be a new species to science. This exciting discovery is one of the many secrets that deposits of Baltic amber have revealed in the last years and are yet to come in […]

First 3-D pterosaur eggs found with their parents

Researchers have discovered the first three-dimensionally preserved pterosaur eggs in China. The eggs were found among dozens, if not hundreds, of pterosaur fossils, representing a new genus and species (Hamipterus tianshanensis). The discovery, described in the Cell Press journal Current Biology on June 5, reveals that the pterosaurs — flying reptiles with wingspans ranging from […]

A 66 million year old forest fire sheds light on extinction of the dinosaurs

Source: McGill University As far back as the time of the dinosaurs, 66 million years ago, forests recovered from fires in the same manner they do today, according to a team of researchers from McGill University and the Royal Saskatchewan Museum. During an expedition in southern Saskatchewan, Canada, the team discovered the first fossil-record evidence […]
