Ajnabia (meaning "stranger" or "foreigner") is a genus of lambeosaurine hadrosaur from the Late Cretaceous (Maastrichtian) of Morocco. It is the first definitive hadrosaur from Africa, and is thought to be related to European dinosaurs like Arenysaurus.[1] The discovery of Ajnabia came as a surprise to the paleontologists who found it, because Africa was isolated by water from the rest of the world during the Cretaceous, such that hadrosaurs were assumed to have been unable to reach the continent.[2][3] Ajnabia is relatively small and similar in size to its contemporary relative Minqaria, which is estimated to have reached 3.5 metres (11 ft) in total body length.[4] Assuming that the holotype represents an adult, Ajnabia would be one of the smallest if not the smallest known hadrosaurids.
