What feeding function is inferred from the peg-like dentition of Xenoposeidon?
Answer
Cropping or raking vegetation
The morphology of Xenoposeidon's teeth, described as peg-like and specialized, suggests a functional purpose different from heavy mastication. These teeth were not designed for grinding like mammalian teeth, nor were they as efficient at shearing vast amounts of tough, woody material as seen in some other contemporary sauropods like brachiosaurids. Instead, the inferred function aligns with cropping or raking foliage, acting as a simple rake to pull vegetation into the mouth cavity. The material was then swallowed relatively whole, relying on subsequent internal processing, such as fermentation and mechanical breakdown in the gut, to extract nutrients.
