IV.—The Hyracoid Pliohyrax græcus (Gaudry) from the Upper Miocene of Samos and Pikermi

Abstract

Amongst the hosts of Antelopes, Rhinoceroses, Hipparions, etc., which form the bulk of the Pikermi fauna described in Gaudry's classical “Animaux Fossiles et Géologie de l'Attique,” the mandible of Leptodon græcus, with lower molars recalling the Palæotheres and Paloplotheres, seemed to stand out, as it were, as an anachronism. It has always appeared to me, as it may also have to others, that the occurrence of such a type in the above company (with which Orycteropus and the Ostrich are also associated, in the contemporary beds of Samos) might be accounted for in a satisfactory manner, if Leptodon could be shown to be related to the Hyraces.
