Panthera tigris sudanensis is a possible subspecies of tiger sighted in Africa. It was described by Paul E. P. Deraniyagala in 1951, after he saw a fur he saw at a Cairo bazaar. When asked for information, the seller told Deraniyagala that the animal was shot in the Sudan. As Mazák wrote in 1980, "it was either a joke or the seller felt obliged to be polite and answer any question, whether with truth or an invention". Deraniyagala took a photo of the fur. After it was published, scientists said that, based on the pattern of the stripes, it was probably a fur of a Caspian tiger (Panthera tigris virgata) and that the fur was smuggled from Iran or Turkey. The Caspian tiger was almost extinct at that time. If the photo was enough for a scientific description, Panthera tigris sudanensis would now be one of the Caspian tiger synonyms. Mazák wrote that, "the situation is half-humorous, half-ironic.
