Tastavinsaurus is a genus of sauropod dinosaur belonging to the Titanosauriformes. It is based on a partial skeleton from the Early Cretaceous Xert Formation of Spain . The type species is Tastavinsaurus sanzi, named in honor of the Rio Tastavins in Spain and Spanish paleontologist José Luis Sanz.[1] Tastavinsaurus sanzi is known from two specimens, one from the Xert Formation and one from the Forcall Formation.[2] Tastavinsaurus was originally described as a somphospondylan,[1] but it may be a brachiosaurid.[3] The clade Laurasiformes was coined for Tastavinsaurus and its close relatives, which may include Cedarosaurus, Soriatitan, and Venenosaurus.[2][3]
Description
The length of Tastavinsaurus sanzi has been estimated to be 16 metres (50 feet), and its weight has been estimated to be 8 tonnes.[4] The caudal vertebrae are similar to those of other basal titanosauriforms, such as Cedarosaurus.[1] The shin was proportionally shorter than in other sauropods, with the length of the tibia being only 55% of the length of the femur.[2]
