Xenoposeidon's inferred evolution suggests a history distinct from which of these groups, known for being more slender and long-necked?
Answer
Diplodocoidea
When tracing the major themes in sauropod evolution, there is a shift noted from more slender, longer-necked forms like Diplodocoidea toward the robust and immensely bulky Titanosauria. *Xenoposeidon*, even based on its limited skeletal evidence suggesting specialized, robust vertebral structures characteristic of later sauropods, appears to have evolved separately from the lineage represented by the Diplodocoidea group.
