What caloric resource provided a competitive advantage to the bone-crushing *E. haydeni*?
Answer
Marrow locked inside thick bone
The specialization of *Epicyon haydeni* as a bone crusher provided a significant ecological advantage in an environment rich with large herbivores. By possessing the capability to process thick bone, *E. haydeni* could access marrow and fat stores locked within the skeletal structure after a kill or scavenging opportunity. This access to deep, dense caloric resources was crucial for survival and provided a competitive edge over carnivores limited strictly to processing muscle and organ meat, defining its role as an expert resource exploiter.
