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 []

Best Paleontology Schools in US Following a career in studying dinosaurs is not easy, but it can be very rewarding if it is your passion. A bachelors degree only scratches the surface, but your path to the fossil world definitely starts from there. It is important to note that paleontology is not only related to []

Precambrian Era The Precambrian Era, also known as the Precambrian Supereon, is a period of time in Earths history that covered approximately 4 billion years, which is about 90% of the entire history of the Earth. It starts about 4.56 billion years ago when the Earth was formed and ends about 541 million years ago []

Did Dinosaurs Really Have Feathers? Science is learning more and more about the versatility of form in dinosaurs with each great find in China, the Americas, Antarctica, and elsewhere. During their heyday in the Triassic, Jurassic, and Cretaceous periods, dinosaurs evolved to fill niches in most ecosystems. Some were large, some were small, some walked []

Quaternary Period Quaternary Period is the current and most recent of the threeperiodsof the CenozoicErain thegeologic time scaleof theInternational Commission on Stratigraphy(ICS). It follows theNeogenePeriodand spans from 2.588 0.005 million years ago to the present. The Quaternary Period is divided into two epochs: thePleistocene(2.588 million years ago to 11.7 thousand years ago) and theHolocene(11.7 thousand []

The titanosaur dinosaur Dreadnoughtus schrani (pictured above) is the only supermassive dinosaur for which scientists have both the femur and humerus bones from the same individual. That makes it the largest dinosaur for which scientists can confidently calculate a mass. However, Argentinosaurus is likely the largest dinosaur, by mass, on record. The battle for the []

Following both thePrecambrian Timeand thePaleozoic Eraon the Geologic Time Scale came the Mesozoic Era. The Mesozoic Era is sometimes called theage of the dinosaursbecause dinosaurs were the dominant animals for much of the era. The Permian Extinction After the Permian Extinction wiped out over 95% of ocean-dwelling species and 70% of land species, the new []
