Kasai Rex
In 1932, a Swedish plantation owner named John Johnson and his servant were in Africa when they reported the first sighting of the Kasai Rex. During their observation of rhinoceros while attempting to stay inconspicuous, the Kasai Rex allegedly emerged suddenly from nearby undergrowth, launching an attack on the rhinoceros in the vicinity. In response, the servant fled, while Johnson himself fainted. Upon regaining consciousness, Johnson discovered the creature feasting on the slain rhinoceros.
While the scientific consensus leans heavily against the survival of non-avian dinosaurs, the allure of discovering a living link to prehistoric times continues to intrigue and inspire explorers, researchers, and enthusiasts alike. Several species thought to have been extinct later turned out to still be living, like the coelacanth rediscovered in 1938.
