Boualitomidae Sp

	Boualitomidae Sp 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.E.

picture info	Paleocene The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

It is bordered by Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the south ...). Description ''Galecyon'' had robust canines and short, deep jaws. Prior to 2015, little was known about its post-cranial skeleton.
