Khinjaria acuta, our new Mosasaur from the late Maastrichtian of Morocco. Khinjaria had a short face, a cruel-looking smile and a mouth full of teeth like knives; it looked positively demonic. At around 7-8 meters (25 feet) long it was larger than a great white shark. A top predator, although not at the very top of the food chain. It was one of a diverse host of predators, including Thalassotitan atrox, Hainosaurus, Mosasaurus beaugei, and Prognathodon currii that existed in the late Maastrichtian. Our paper can be found here in Cretaceous Research:

New duckbill dinosaur from Morocco. A few years ago, we found the first duckbill dinosaur from Africa, an animal we named Ajnabia. When another duckbill turned up, we assumed it would be that species. It turned out to be something new, a creature we named Minqaria bata (Arabic for 'beak' and 'duck'). When duckbill dinosaurs arrived in North Africa at the end of the Cretaceous, they rapidly underwent a radiation, like when finches arrived in the Galapagos.

Tyrannosaurus mcraeensis was 5-6 million years older than T. rex but just as big. It suggests Tyrannosaurus evolved in southern North America before spreading north at the end of the Maastrichtian

Rumors of the demise of Nanotyrannus are greatly exaggered. Multiple lines of evidence- paleoecology, growth series, histology, phylogenetics and a juvenile T. rex all show incontrovertibly that Nanotyrannus was not a juvenile T. rex, but a distinct genus of basal tyrannosauroid.

Although many species have been assigned to the Hypsilophodontidae over the years, all except Hypsolophodon have ended up in separate families. Here, after more than a century, we describe the second true member of the Hypsilophodontidae. Hypsilophodonts appear to have been a European endemic clade.

Fossils suggest three distinct species of abelisaurids inhabited the latest Cretaceous of Morocco, in North Africa.
