Them Bones: School-bus-sized dinosaur fossil unearthed in Egypt’s Western Desert. Egyptian paleontologists from Mansoura University have unearthed in Egypt’s Dakhla Oasis fossils of a long-necked, school bus-sized dinosaur that lived roughly 80 mn years ago, Reuters reports. The team recovered parts of the Mansourasaurus shahinae’s skull, lower jaw, neck and back vertebrae, ribs, shoulder and forelimb, back foot and osteoderms. They named the 5.5-tonne herbivore after the town where the university is located, as well as Mona Shahin, who helped develop the Mansoura University Vertebrate Paleontology project. The discovery sheds light on a mysterious time period in the history of dinosaurs in Africa.
