Why must interpretations of Xenoposeidon's limb length or skull shape be treated with significant caution?

Answer

These elements are entirely unknown

Any interpretation regarding the overall body plan of *Xenoposeidon*, including specifics like limb length, tail structure, or skull shape, must be approached with extreme caution. This necessity for caution arises directly because the entirety of the confirmed physical evidence consists solely of the cervical vertebra; therefore, all other skeletal elements required to construct a full body map are entirely unknown and purely speculative.
