Published in PLOS ONE today, a study by an international team from the Perot Museum of Nature and Science in Dallas and Hokkaido University in Japan further explores the proliferation of the most commonly occurring duck-billed dinosaur of the ancient Arctic as the genus Edmontosaurus. The findings reinforce that the hadrosaurs - dubbed "caribou of the Cretaceous" - had a geographical distribution of approximately 60 degrees of latitude, spanning the North American West from Alaska to Colorado.

Predators abound on land, in the air and in water some 95 million years on the shores of northern Africa -- as shown by the abundant fossils in the Kem Kem region. Large herbivores, such as the long-necked sauropod Rebbachisaurus, could have been hunted or scavenged by several large predators. Credit: Artwork by Davide Bonadonna

A new feathered dinosaur that lived in New Mexico 67 million years ago is one of the last known surviving raptor species, according to a new publication in the journal Scientific Reports. Dineobellator notohesperus adds to scientists' understanding of the paleo-biodiversity of the American Southwest, offering a clearer picture of what life was like in this region near the end of the reign of the dinosaurs.

This mural was originally made for a recent Royal Ontario Museum exhibit about a fossil ankylosaur named Zuul crurivastator. That fossil is found within a couple of meters stratigraphically/temporally of the site described in this paper. The last author on the study, David Evans, is the dinosaur curator at the Royal Ontario Museum and was also involved in the description of Zuul and design of that exhibit.
