What catalog number identifies the singular *Xenoposeidon proneneukos* dorsal vertebra specimen?
Answer
NHMUK PV R2095
The unique fossil evidence supporting the existence of *Xenoposeidon proneneukos* is tied to a specific catalog number assigned to the single recovered specimen. This particular dorsal vertebra, which consists of a mid-to-posterior section, is officially designated as NHMUK PV R2095. This designation confirms its status as the holotype specimen and allows for its current location to be tracked and verified, specifically noting that it is housed today at The Natural History Museum in London. The singular nature of this specimen makes its catalog number fundamental to all subsequent paleontological study regarding this species.
