Epicyon (SciiFii)

The hyena dog (Epicyon hyaena) is a species of canid of the subfamily Borophaginae ("bone-crushing dogs") that originally lived in North America during the Miocene as an extinct species of Epicyon and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the forests, open woodlands, grasslands, and shrublands across North America to help boost biodiversity. The hyena dog fills the similar ecological niche to the bone-crushing hyenas of the Old World (including spotted hyenas), having shortened, yet strong jaws with thick teeth for crushing bones, allowing hyena dogs to hunt even larger animals than gray wolves, one of its rivals. The hyena dog is also one of, if not, the largest canids that have ever existed, growing to be about 5 feet (1.5 meters) long and weigh about 91–136 kg (200–300 lb), about the size of a subadult lion. The hyena dog is a social animal that lives in packs up to around 80 at a time, similarly to the spotted hyenas of the Old World (which fills a similar ecological niche), so it could hunt down animals as large as rhinos, however, the packs are led by dominant males, unlike spotted hyenas. The conservation status of the hyena dog is Least Concern due to successful conservation efforts, the hyena dog's wide range and its tolerance to many of the human activities.
