New Mygatt-Moore quarry research leads to prehistoric climate finds

Life restoration of Kongonaphon kely, a newly described reptile near the ancestry of dinosaurs and pterosaurs, shown to scale with human hands. The fossils of Kongonaphon were found in Triassic (~237 million years ago) rocks in southwestern Madagascar and demonstrate the existence of remarkably small animals along the dinosaurian stem.

Famous ‘Jurassic Park’ dinosaur is less lizard, more bird

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
