Abstract
This work describes a new specimen of the sauropod Tastavinsaurus sanzi,
the second of this species recovered. Found at the La Canaleta site (CT-19)
at El Castellar (Teruel, Spain), this new specimen is partially
articulated. The site lies at the base of the Forcall Formation (early
Aptian in age), which is composed of clays and sand, suggesting the area to
have been a very shallow, tidal, coastal environment before becoming deeper
at the margin of the Maestrazgo Basin. The anatomical elements of T. sanzi
recovered include 16 dorsal ribs, some remains of the pelvic girdle, a
radius, and a complete hindlimb. The original diagnosis of T. sanzi is
revised. The characters of this new specimen confirm it to be a taxon of
Titanosauriformes, and allow its inclusion within the clade Laurasiformes,
which currently has three taxa: Tastavinsaurus, Cedarosaurus and
Venenosaurus. Laurasiformes might have its origin in the Late Jurassic of
Laurasia and a radiation that occurred in the Early Cretaceous.
