Galecyon

	Galecyon ''Galecyon'' ("polecat-dog") is a genus of hyaenodonts that lived during the early Eocene in Europe and North America (found in the Clarks Fork and Powder River basins of Wyoming Wyoming () is a U.S. state, state in the Mountain states, Mountain West subregion of the Western United States. 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. However, following the discovery of more complete fossils, it is now known to have been a primarily terrestrial animal weighing between , lacking the adaptations for climbing found in some of its close relatives.

picture info	Hyaenodonta Hyaenodonta (" hyena teeth") is an extinct order of hypercarnivorous placental pan-carnivoran mammals from mirorder Ferae. Hyaenodonts were important mammalian predators that arose during the early Paleocene in Europe and persisted well into the late Miocene. Characteristics Hyaenodonts are characterized by long skulls, slender jaws, slim bodies and a plantigrade stance. They generally ranged in size from 30 to 140 cm at the shoulder. While '' Simbakubwa kutokaafrika'' may have been up to (surpassing the modern polar bear in size) and ''Hyaenodon gigas'' (the largest species from genus ''Hyaenodon'') was as much as 1.4 m high at the shoulder, 3.0 m long and weighed about 330 kg, most of hyaenodonts were in the 5–15 kg range, equivalent to a mid-sized dog. The anatomy of their skulls show that they had a particularly acute sense of smell, while their teeth were adapted for shearing, rather than crushing.
