Within which major sauropod clade is Xenoposeidon most frequently assigned, known for dominating the Late Cretaceous?
Answer
Titanosauria
*Xenoposeidon* is most frequently assigned phylogenetically within the Titanosauria, which represents the group containing the dominant and often largest land animals of the Late Cretaceous epoch. Initial assessments of the cervical vertebra showed features linking it closely to advanced titanosaur groups, and some analyses have specifically placed it within the Lithostrotia, a major subgroup of Titanosauria.
