Boualitomidae ("Bou Alian cutters") is a family of extinct predatory mammals from extinct order Hyaenodonta. Fossil remains of these mammals are known from middle Paleocene to late Eocene deposits in Africa. Boualitomids had only three pairs of premolars in the lower dentition, lacking the first one. ^{[2] [3] [4]}
