The amount obtained by the auction of the fossil remains of the dinosaurs surprised all the experts, who had valued the T-Rex between 6 and 8 million dollars. The sample has around 300 pieces. Stan, a T. Rex almost four meters high and another twelve from the head to the last vertebra of the tail, []
Oldest dinosaur embryos ever found A group of American paleontologists has identified the oldest dinosaur embryos discovered so far. Preserved almost intact inside eggs found in 1976 in South Africa, they belong to a species that lived 190 million years ago, and which was the ancestor of the giant four-legged, long-necked prosauropods, such as Diplodocus.

While dinosaurs ruled the land in the Mesozoic, the oceans were filled by predators such as crocodiles and giant lizards, but also entirely extinct groups such as ichthyosaurs and plesiosaurs. Now for the first time, researchers at the University of Bristol have modelled the changing ecologies of these great sea dragons. Mesozoic oceans were unique []

A team of scientists finds remains of pollen, spores and even roots in a sediment sample from 90 million years ago found in the Amundsen Sea.His analysis has made it possible to reconstruct the climate of that time and reach surprising conclusions. 90 million years ago, when thedinosaurswere at their peak, the west coast of []

How Smart Were Dinosaurs? Some paleontologists point out that the most insightful may have been the small theropods of the genus Troodon, which lived about 70 million years ago in present-day North America. They werent very big, just over six feet long and one meter tall, weighing around 50 kilos, but apparently they had relatively []

Dinosaurs were cold too Ateam of paleontologists from France and China has shown thatduring a part of the Lower Cretaceous, temperatures were colder than previously assumed, which implies that in the age of the dinosaurs the climate was not always warm. The paleontologists authors of the study determined the temperatures of the timefrom fossils of []

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 disappearand, suddenly, nobody else eats the vegetation. That means agreat availability of food, []

What do we know about that killer rock that darkened the skies for dozens of years, raised the volume of the sea above the heads of large animals, and caused earthquakes and violent volcanic events? Themass extinction eventof 65 million years ago, which wiped out most of Earths species (including dinosaurs) has been widely publicized []

The firstdinosaursevolved during the middle to late Triassic period, about 230 million years ago, in the part of the super continent ofPangeathat currently corresponds to South America.Before that, the dominant terrestrial reptiles were archosaurs (dominant reptiles), therapsids (mammal-like reptiles), and pelycosaurs (such as the Dimetrodon that lived during the Permian period).The earliest archosaurs are believed []

How many dinosaurs were there? Many people question the number ofdinosaurs that existedon Earth.This question actually makes a lot of sense, especially when you know that these giant reptiles have been the longest-ruling the world.If you want to know what is known about this matter, you are in the right place. Dinosaurs existed for at []
