Canidae : The mammal family that includes wolves, foxes, coyotes, jackals, and domestic dogs. The dire wolf belonged to this family of canids.
Carnivory : A feeding strategy in which animals obtain nutrients by eating other animals. Dire wolves were meat-eating predators and scavengers.
Canid evolution : The evolutionary history and diversification of the dog family, Canidae. The dire wolf represents a distinctive branch of North American canid evolution.
Rancho La Brea : A fossil-rich site in Los Angeles, now known for the La Brea Tar Pits. Its asphalt deposits preserve exceptionally many dire wolf specimens.
Gray wolf : A large, widespread canid, Canis lupus, and the closest living comparison for the dire wolf. Comparing the two highlights the dire wolf’s robust build and distinct lineage.
Megafauna : Large-bodied animals, especially those prominent in an ecosystem or extinct fauna. Dire wolves shared Pleistocene North America with large potential prey.
Aenocyon dirus : The extinct species commonly called the dire wolf, known from Pleistocene fossils in the Americas. It is the species name used for the dire wolf.
Natural Trap Cave : A limestone pit cave in Wyoming that accumulated fossils of Pleistocene animals. Its deposits preserve dire wolf remains from a different setting than La Brea.
Pleistocene : A geological epoch lasting from about 2.58 million to 11,700 years ago, marked by repeated ice ages. Dire wolves lived across North America during this epoch.
La Brea Tar Pits : A group of asphalt seeps in Los Angeles that trapped and preserved thousands of Ice Age animals. Their fossils provide an unusually large sample of dire wolf remains.
