What mechanical function was the robust, deep structure of the *Gastornis* beak found to be optimized for?
Answer
Applying significant, sustained pressure across a broad surface area
The biomechanics indicate the beak was designed not for quick tearing, but for applying consistent, heavy pressure, ideal for processing hard-shelled items.
