Hypocarnivore
Animal consuming less than 30% meat, mostly fungi and plants.
A hypocarnivore is an animal that consumes less than 30% meat for its diet, the majority of which consists of fungi, fruits, and other plant material. Examples of living hypocarnivores include the grizzly bear, black bear, binturong, and kinkajou. The term is used with increasing frequency in describing early Canidae evolution, and reliance upon that survival strategy has a documented history in North American Borophaginae during the Miocene.

Lore & Background
The evolutionary division of carnivorans into three groups, including hypercarnivore and mesocarnivore, appears to have occurred about 40 million years ago. Twenty-five species of hypocarnivore are documented as co-occurring on the North American continent 30 million years ago. A shift from hyper- to hypocarnivory occurred at least three times among Oligocene and Miocene canids: Oxetocyon, Phlaocyon, and Cynarctus.
Reader's Guide
Hypocarnivores represent a distinct dietary strategy within the order Carnivora, defined by a meat intake below 30% and a reliance on fungi, fruits, and plant material. This feeding behavior has deep evolutionary roots, with evidence in North American Borophaginae during the Miocene and multiple independent shifts from hypercarnivory in canid lineages. The dentition of hypocarnivores shows expanded post-carnassial molar volume, reflecting adaptation to grinding plant foods, as seen in Prohesperocyon. Large hypocarnivores like Ursus were rare and developed in the mid-to-late Miocene-Pliocene as borophagines became extinct. Understanding hypocarnivory clarifies the ecological diversity of carnivorans and the evolutionary flexibility of dietary niches.
