Which structure was the workhorse for initial breakdown of bulk foliage in Xenoceratops?
Answer
Parrot-like beak
The specialized, parrot-like beak served as the primary tool for dietary management in Xenoceratops. This beak was specifically engineered not only for gathering vegetation but also for the essential tasks of cutting and shearing tough material. Given the massive bulk and energy demands of an animal estimated to weigh over 2 tons, this initial mechanical processing had to be highly effective. The beak handled the initial cropping of tough greens and tearing leaves from stalks, performing the critical first step before the plant matter moved into the internal digestive system for breakdown.
