During what geological period did Xenoposeidon exist, based on its association with the Wealden clays?
Answer
Early Cretaceous
The fossil material associated with *Xenoposeidon* was discovered in the United Kingdom within the Wealden clays. This geological context firmly places the creature's existence during the Early Cretaceous period. This timing is significant because it precedes the main explosion of the most famous, colossal titanosaurs found later in the Late Cretaceous period, suggesting *Xenoposeidon* was an early experiment in gigantism within Europe.
