> New sauropod dinosaur material is described from Jones Ranch, Early
> Cretaceous of Texas (USA). Originally described as Paluxysaurus
> jonesi, the material from Jones Ranch has recently been referred to
> Sauroposeidon proteles. Elements newly prepared from dense

> sauropod that was originally regarded as closely related to
> Brachiosaurus. Portions of the sacrum are now exposed and show that it
> is nearly complete, missing only parts of the first sacral (S1). The
> anterior sacrals are firmly fused, however, a newly discovered
> opisthocoelous last sacral (S6) remains unfused. A complete sequence
> of proximal caudal vertebrae shows a rapid transition from
> anteroposteriorly short and mediolaterally broad centra anteriorly, to
> more elongate cylindrical centra posteriorly. All proximal caudals
> have slightly amphicoelous centra. Some middle anterior caudals have a
> shallow longitudinal groove on the ventral surface of the centrum.
> Specimens from Jones Ranch exhibit characters of the sacrum and tail

nt of ‘P. jonesi’ (Sauroposeidon
> proteles) as a somphospondylan titanosauriform.
