What other major sauropod group is mentioned alongside Titanosauria as potentially existing in the Hastings Beds Group during the Early Cretaceous?
Answer
Diplodocidae
The fragmented remains found within the Wealden sediments, particularly those associated with the Hastings Beds Group, suggest that the environment supported a surprising diversity of large herbivores. Analysis of these bones indicates the presence of several distinct sauropod groups coexisting or overlapping temporally and spatially. Specifically mentioned as being present in this assemblage, alongside basal Titanosauriformes and Titanosauria, is the Diplodocidae family. The appearance of a rebbachisaurid (*Xenoposeidon*) within this already diverse milieu underscores that the Early Cretaceous English mainland was a significant, though complex, center for sauropod fauna.
