Relative to the Wessex Formation, how does the geological age of the Hastings Beds Group containing *Xenoposeidon* compare?
Answer
It is older
The geological sequence of the Wealden Supergroup is differentiated chronologically across its units. The Hastings Beds Group, where the holotype NHMUK PV R2095 was recovered, captures the earliest part of the Early Cretaceous period, spanning the Berriasian–Valanginian stages. Conversely, the Wessex Formation, which dominates later sauropod records, for example, from the Isle of Wight, represents younger strata within the broader Wealden assemblage. Therefore, the strata yielding *Xenoposeidon* are chronologically older than the geological deposits from which many later sauropod remains in the region have been sourced.
