What is a bone train?

A bone train is a term used to describe a type of bone transport system found in some species of animals, particularly in the context of scavenging behaviors. It refers to the sequential movement of bones from a carcass to a specific location, often done by scavengers like hyenas or vultures. These animals may transport bones to communal feeding sites or nesting areas, facilitating a more efficient utilization of resources. The term can also evoke imagery of a train of scavengers working together to move and break down a carcass.
