Machaerodus, the "sabre-toothed tigers," are a genus of extinct Carnivora remarkable for the enormous development of their canine teeth, and also for a wide distribution both in time and space. They occur in the Miocene beds of the Val d'Arno, Italy, of Auvergne and of Eppelsheim; in the sandstones of the Sivalik Hills (q.v.), India; in Pampas deposits and bone-caves of South America; in the Cromer Forest-bed and, apparently associated with human remains, in Kent's Cavern (q.v.), Torquay.
