       The fossil material for Magericyon was originally described as a species of Amphicyon until a new study by Peigne et al‭ ‬in‭ ‬2008.‭ ‬Magericyon was found to be different from Amphicyon by close study of the form and proportion of the teeth.‭ ‬In naming the new genus the describers chose the name Magericyon from the word Magerit,‭ ‬the original name for Madrid combined with the ancient Greek for cyon which means dog.‭ ‬Magericyon was further split into two species with M.‭ ‬anceps having shorter and narrower canine teeth than M.‭ ‬castellanus.
       Magericyon remains are known from the Cerro de Battalions area of Spain which has been interpreted as a natural predator trap due‭ ‬to the exceptionally high abundance of carnivorous mammals in this area.‭ ‬Studies of modern large predatory mammals indicate that predators most likely to go after animals and carrion stuck in predator traps are those that live in groups,‭ ‬although solitary predators are also known to do this.‭ ‬This might hint at possible pack hunting for Magericyon,‭ ‬particularly since juvenile remains have also been found,‭ ‬although this may be indicative of family groups where the young stay and scavenge with the parent.
       Other predators known from this region include sabre-toothed cats such as Machairodus.
