The film Jurassic Park was right about one thing: velociraptors hunted at night while large herbivores also foraged during the day, according to an American study just published in the popular magazine Science.

Irish scientists have identified a new species of giant theropod dinosaur, a close relative of Tyrannosaurus rex, from fossilized skull and jaw bones discovered in China. Baptized 'Zhuchengtyrannus magnus', it measured about 11 meters long, 4 meters high and weighed about 6 tons.

The Aragosaurus Research Group of the University of Zaragoza has recovered the remains of a new dinosaur, Petrobrasaurus, about 20 meters long, found in an oil drilling in northern Patagonia (Argentina).

Argentine paleontologists have found the remains of a small bipedal dinosaur, which lived 230 million years ago and could be the ancestor of all predatory dinosaurs, including 'Tyrannosaurus rex'. They have christened it 'Eodromaeus murphi', which means "corridor of dawn".

A group of paleontologists has identified the oldest dinosaur embryos discovered so far. They belong to the species 'Massospondylus', and their bodies have been preserved almost intact inside eggs for 190 million years.

In Poland, traces of footprints barely two centimeters long belonging to primitive dinosaurs with a size similar to that of a domestic cat, walking on all fours, have been found. The footprints are 250 million years old.

The dinosaurs were clearly larger than previously thought, a new study by American paleontologists reveals. According to the scientists, these animals possessed thick cartilage that could have added about 12 inches to the size of the dinosaurs. The difference could have effects on the posture of the dinosaurs and the speed of their movements.

Paleontologists from the Fundación Conjunto Paleontológico de Teruel-Dinópolis have discovered, at the Riodeva site, in the province of Teruel, a gigantic dinosaur femur. The bone, measuring almost two meters, is the longest ever found in Europe.
