Helium leakage from Earth’s mantle ?

UC Santa Barbara geologist Jim Boles has found evidence of helium leakage from Earth’s mantle along a 30-mile stretch of the Newport-Inglewood Fault Zone in the Los Angeles Basin. Using samples of casing gas from two dozen oil wells ranging from LA’s Westside to Newport Beach in Orange County, Boles discovered that more than one-third […]

Sefapanosaurus — SA’s new Sesotho dinosaur.

South African and Argentinian palaeontologists have discovered a new 200-million-year-old dinosaur from South Africa, and named it Sefapanosaurus, from the Sesotho word “sefapano.” The researchers from South Africa’s University of Cape Town (UCT) and the University of the Witwatersrand (Wits University), and from the Argentinian Museo de La Plata and Museo Paleontológico Egidio Feruglio made […]

Dinosaur tracks reconstructed

Twelve years ago, footprints of carnivorous dinosaurs were discovered and excavated in a quarry near Goslar. Paleontologists from the University of Bonn, working with Dinosaur Park Münchehagen and the State Museum of Hanover, have now created a three-dimensional digital model based on photographs of the excavation. The reconstruction of the discovery site suggests that carnivorous […]

First sensor of Earth’s magnetic field in an animal

A team of scientists and engineers at The University of Texas at Austin has identified the first sensor of Earth’s magnetic field in an animal, finding in the brain of a tiny worm a big clue to a long-held mystery about how animals’ internal compasses work. Animals as diverse as migrating geese, sea turtles and […]

When continents connected ?

A long-standing fact widely accepted among the scientific community has been recently refuted, which now has major implications on our understanding of how Earth has evolved.Until recently, most geologists had determined the land connecting North and South America, the Isthmus of Panama, had formed 3.5 million years ago. But new data shows that this geological […]

Red Blood Cells in Fossil Fragments?

Scientists have found remnants that have some similarities to red blood cells and collagen fibres in fragments of dinosaur fossils. The team from Imperial College London have detected what look like soft tissue remnants in the fragments of 75 million year old dinosaur fossils even though the fossils are poorly preserved. Scientists have previously only […]

Paleo-engineering on triceratops’ teeth revealed

When it comes to the three-horned dinosaur called the Triceratops, science is showing the ancient creatures might have been a little more complex than we thought.In fact, their teeth were far more intricate than any reptile or mammal living today. Biological Science Professor Gregory Erickson and a multiuniversity team composed of engineers and paleontologists content […]

Earthquake was felt from Space

For the first time, a natural source of infrasonic waves of Earth has been measured directly from space–450 kilometers above the planet’s surface. The source was the massive 2011 Tohoku-Oki earthquake in Japan, and its signature was detected at this orbital altitude only eight minutes after the arrival of seismic and infrasonic waves, according to […]

Clues to Earth’s ancient core

Old rocks hold on to their secrets. Now, a geophysicist at Michigan Technological University has unlocked clues trapped in the magnetic signatures of mineral grains in those rocks. These clues will help clear up the murky history of Earth’s early core. The journal Earth and Planetary Science Letters published a paper on the subject earlier […]

Britain’s oldest sauropod

Experts from the University of Manchester have identified Britain’s oldest sauropod dinosaur from a fossil bone discovered on the Yorkshire coast. The vertebra (backbone) originates from a group of dinosaurs that includes the largest land animals to have ever walked on Earth. This new sauropod dinosaur, from the Middle Jurassic Period at about 176 million […]
