How did the initial processing by Xenoposeidon's teeth compare to brachiosaurids?
Answer
Less efficient at shearing tough material than brachiosaurids
The dentition of Xenoposeidon, characterized as peg-like and specialized for cropping or raking, suggests an inability to handle tough vegetation as effectively as some contemporaries. Specifically, this morphology was likely not as efficient at shearing large quantities of tough, woody material compared to the functional capabilities attributed to brachiosaurids. The limitation in initial mechanical breakdown meant that Xenoposeidon relied heavily on its massive internal processing system to handle the fibrous diet, a less direct approach than extensive initial processing.
