The horse was particularly important as a prey animal in the eastern Beringian context.

Horses of the Last Glacial Maximum were, by stable isotope analysis of their bones and teeth, primarily grazers — they were eating the productive grasses of the mammoth steppe.

They were large animals, providing substantial amounts of meat, fat, hide, and bone per carcass.

A successful horse hunt or scavenging event was, in terms of caloric and material resources, a major economic event for a small group of hunter-gatherers.

The fact that the most important dated specimen from Bluefish Caves is a horse mandible with cut marks is not accidental.
