Earthquakes: Friction and Fracture are interrelated

Overturning conventional wisdom stretching all the way to Leonardo da Vinci, new Hebrew University of Jerusalem research shows that how things break (fracture) and how things slide (friction) are closely interrelated. The breakthrough study marks an important advance in understanding friction and fracture, with implications for describing the mechanics that drive earthquakes. Over 500 years […]

Argentavis magnificens: Largest Prehistoric Bird

Scientists have identified the fossilized remains of an extinct giant bird that could be the biggest flying bird ever found. With an estimated 20-24-foot wingspan, the creature surpassed size estimates based on wing bones from the previous record holder — a long-extinct bird named Argentavis magnificens — and was twice as big as the Royal […]

Ammonite fossil discovered in Hawkes Bay

The fossil of a squid-like creature wiped out with the dinosaurs has been discovered in a Hawkes Bay streambed. The surprise find of the ammonite fossil – found contained in a 50kg boulder in the Waiau River – has excited scientists about what other specimens may lay hidden in New Zealand’s under-explored wilderness.

Scientists Discover Why Female Dinosaurs Laid Smaller Eggs

A team of researchers have discovered that though dinosaurs were the largest creatures to have ever walked on Earth, they did not lay the world’s largest eggs. Both individual egg size and clutch size of sauropods, one of the largest group of dinosaurs, were found to be a lot smaller than previously thought. Sauropods, including diplodocus, […]

New specimen of Archaeopteryx reveals previously unknown features of the plumage

Paleontologists of Ludwig-Maximilians-Universitaet (LMU) in Munich are currently studying a new specimen of Archaeopteryx, which reveals previously unknown features of the plumage. The initial findings shed light on the original function of feathers and their recruitment for flight. A century and a half after its discovery and a mere 150 million years or so since […]
