What was the primary mechanism for nutrient extraction in Xenoposeidon?
Answer
Fermentation powered by gut microbes
Because the peg-like teeth provided limited pre-mastication, the bulk of nutrient extraction occurred internally, which is characteristic of sauropod biology. This process relied on a gigantic fermentation vat housed within its long intestinal tract. This internal mechanism housed diverse bacterial colonies capable of breaking down complex structural carbohydrates like cellulose and lignin found in fibrous plant matter. The food spent a very long time passing through the system, sometimes weeks, allowing for the maximum possible energy extraction from low-quality forage through microbial action rather than mechanical breakdown in the mouth.
