Which genus did Richard Lydekker initially assign specimen BMNH R2095 to in 1893?
Answer
Cetiosaurus brevis
The single bone forming the basis of *Xenoposeidon* knowledge, cataloged as BMNH R2095, went through several provisional assignments over time. When Richard Lydekker first briefly described it in 1893, shortly after its discovery by Philip James Rufford, he tentatively placed it within the species *Cetiosaurus brevis*. This classification was not final; subsequent historical reassignments shifted it to *Pelorosaurus conybearei* before Mike Taylor finally recognized its distinctiveness much later, leading to the establishment of the new genus *Xenoposeidon* in 2007. The initial description by Lydekker represents the first attempt to formally categorize this peculiar vertebra.
