Facts pertaining to fox skulls vary by species. However, all fox skulls can be differentiated from other Canis members – like dogs, wolves, coyotes and Jackals – by their flatter appearance.
Like all predators, foxes have frontally located orbits, or eye sockets, denoting the binocular vision required to locate and chase prey. A fox’s foramen magnum, a hole in the back of the skull where the spinal cord and skull connect, is located near the rear, which is typical of all quadruped animals. A rear-located foramen magnum allows the animal to travel on all four legs while carrying its head nearly parallel with the ground. Since foxes are classified as carnivorous, meaning their diet is mainly or solely compromised of meat, their skulls have accentuated canines located in the front of the mouth. These are used for piercing and holding prey.
There are 12 species commonly referred to as “true” foxes, all belonging to the genus Vulpes. The most common and widely distributed species is the Vulpes vulpes (red fox). Characteristics specific to the red fox’s skull include a longer and more slender rostrum, more closely spaced temporal ridges of the brain case and a longer and more slender curvature of the canines.
