Borophagus, like other borophagines, are loosely known as "bone-crushing" or "hyena-like" dogs.Though not the most massive borophagine by size or weight, it had a more highly evolved capacity to crunch bone than earlier, larger genera such as Epicyon, which seems to be an evolutionary trend of the group (Turner, 2004).
Often generically referred to as "bone-crushing dogs" for their powerful teeth and jaws, and hyena-like features (although their dentition was more primitive than that of hyenas), their fossils are abundant and widespread; in all likelihood, they were probably one of the top predators of their ecosystems.
Mollusk shells can be crushed to expose soft parts of the prey to digestive juices or the soft parts can be removed from the shell. Species that crush shells are defined by their large and greatly thickened pharyngeal bones. These bones have flat-crowned teeth and along with their dorsal fellows drawn by powerful muscles, create a crushing mill.

Epicyon had a massive head and powerful jaws that were well adapted for bone-crushing, with enlarged fourth premolars like some hyenas, giving its skull a lion-like shape rather than having a skull similar in shape to that of a wolf; the adaptation would have allowed Epicyon to scavenge as well as hunt, giving it access to the nutritious marrow other contemporary carnivores couldn't access.
Here’s how to antiage your dog, according to science.
Dogs can’t be counted on to stop eating when they reach the part of a food that isn't digestible, which includes bones and watermelon rinds but also corn cobs, and peach and avocado pits. (In ...
Borophagus diversidens was named by Cope in 1892. Members of its subfamily, Borophaginae, are loosely known as "bone-crushing" or "hyena-like" dogs.Though not the most massive borophagine by size or weight, it had a more highly evolved capacity to crunch bone than earlier, larger genera such as Epicyon, which seems to be an evolutionary trend of the group (Turner, 2004).
