A new species of megaraptorid dinosaur discovered in Patagonia may help discern the evolutionary origins of the megaraptorid clade, according to a study published July 20, 2016 in the open-access journal PLOS ONE by Rodolfo Coria from...Show More Summary
Temperature Spikes Point to Two Events Causing End Cretaceous Mass Extinction A study of the fossilised shells of several species of bivalves that existed towards the end of the Cretaceous suggests two distinct phases of global warming occurred that instigated mass extinctions. Scientists have debated how much of an impact the eruption of the Deccan […]
Researchers have discovered fossils of a carnivorous dinosaur, known as Murusraptor Barrosaensis, that lived around 80 million years ago during the Cretaceous Period.
Despite their diminutive size, raptors were among the most terrifying dinosaurs to menace the Cretaceous Period. But as the discovery of a new dinosaur called Murusraptor shows, their plus-sized versions, aptly known as “megaraptors,” were considerably worse. Read more...

“Hannah” A New Species of Late Cretaceous Ceratopsian PhD student Scott Persons (University of Alberta, Canada) is one of that admirable breed of young scientists, someone who simply exudes enthusiasm and passion for his work. In the summer of 2015, at a dig site just outside the Dinosaur Provincial Park, Scott spotted the large nasal […]
Tycho: I knew that something strange was going on when I saw that Gabriel had slunk onto Xbox Live. What strange force could compel him? It was Playdead’s Inside, and they made Limbo back in the Cretaceous, so, you know. It’s a pretty fuckin’ strange force. Show More Summary

North America in the Late Cretaceous Some of the most famous dinosaurs of all came from the Late Cretaceous of North America, famous formations such as the Hell Creek Formation of Montana. Model maker Robert Townsend has put together a substantial prehistoric animal themed diorama that illustrates this time in our Earth’s history. For fans […]
Eutherians experienced elevated evolutionary rates in the immediate aftermath of the Cretaceous–Palaeogene mass extinctionAuthors:Halliday et alAbstract:The effect of the Cretaceous–Palaeogene (K–Pg) mass extinction on the evolution of many groups, including placental mammals, has been hotly debated.

Found in a Burmese amber mine: The two new samples, weighing in at only 0.06 and 0.3 ounces (1.6 and 8.51 grams), contain bone structure, tracts of feathers, and soft tissue. They are the first Cretaceous plumage samples to be studied...Show More Summary
Those who go to a masked ball consciously slip into a different role, in order to avoid being recognized so quickly. Insects were already doing something very similar in the Cretaceous: They cloaked themselves in pieces of plants, grains of sand, or the remains of their prey, in order, for example, to be invisible to predators.
