The paleontologists authors of the study determined the temperatures of the time from fossils of […]

When mammals replaced dinosaurs

When dinosaurs became extinct 65 million ago, mammals began to grow, multiplying their size by a thousand in some cases. This is the case of  Deinotherium, a distant relative of elephants that disappeared 2.7 million years ago and weighed 17.00 kilograms. “The dinosaurs disappear and, suddenly, nobody else eats the vegetation. That means a great availability of food , […]

This has raised the question of whether many more of the creatures may have been […]

We thought we knew the biggest dinosaur ever, but it seems someone else might take its place

It seems T. Rex has probably been sensationalized too much. While the iconic carnivore has been the poster dino for the entire Jurassic Park  franchise, there were creatures that made it look like a pet lizard. Titanosaurs trodden the earth from the Jurassic through the mid-late Cretaceous, leaving behind only fragments of their skeletons for scientists to try […]
