What structural element on the Epicyon skull anchored the massive temporalis muscles?
Answer
Sagittal crest
The sagittal crest, which is the ridge of bone running along the top of the skull, serves as a critical anchor point. In hypercarnivores like Epicyon haydeni, which were specialized for powerful bites necessary for bone breakage, this crest provides the necessary surface area for the attachment of the massive temporalis muscles. The volume of these muscles dictates the necessary size and prominence of this cranial feature.
