Pterosaurs were reptiles that diversified during the Mesozoic (between 250 and 65 million years ago) modifying their body design for flight in a very different way from birds and bats. A new species of these ancient flying reptiles has recently been discovered at the Las Hoyas site (Cuenca), and has just been described in the journal PLoS ONE by a Spanish team of paleontologists in which experts from France and Brazil also participate.
150 million years ago a megalosaurus covered with filamentous feathers, similar to fine hair, lived in Germany. Paleontologists who have discovered its fossil remains have named it Sciurumimus because of its bushy tail, in honor of the squirrels of the genus Sciurus. It is the first case of feathered megalosaurus that has been described.
A team of biologists from the University of Manchester has developed a new technique to accurately measure the weight and size of dinosaurs, discovering that they weren't as heavy as previously thought. The conclusions are published in the journal 'Biology Letters'.
Sauropod dinosaurs could have produced enough greenhouse gas methane with their flatulence to increase the Earth's temperature millions of years ago, causing their own "global warming", according to a study published in the journal Current Biology.
Scientists have discovered bones of a pterodactyl - a gigantic flying reptile - in the hollow of the stomach of a Velociraptor that lived in the Gobi Desert (present-day Mongolia) 75 million years ago. The findings suggest that this dinosaur, a carnivore with sickle-shaped claws, could have been primarily a scavenger, as the devoured pterosaur was too large to be considered prey for it.
Until recently, most researchers only took into account the variation in the size of Tyrannosaurus rex's teeth when studying the smile of this extinct carnivore from the time of the dinosaurs.
It is a posture characterized by the fact that the body is bent backwards in the shape of an inverted "c". It is typical in people affected by tetanus, a bacterial infection that causes muscle spasms. The phenomenon can also occur as a result of strychnine poisoning or when poisoned by ingesting lithium.
