Soriatitan golmayensis is a plant-eating sauropod dinosaur belonging to the Titanosauriformes, who lived in the area of ​​present Spain during the Early Cretaceous period.

Discovery and naming[]

At Golmayo in the discovery area Los Caños in the province of Soria, the family Fuentes-Meijide broke out the Zorralbo I site between 2000 and 2004, featuring five skeletons of dinosaurs including Magmananus. One of them was an unknown sauropod.

In 2017, the type of Soriatitan golmayensis was named and described by Rafael Royo-Torres, Carolina Fuentes, Manuel Meijide, Federico Meijide-Fuentes and Manuel Meijide-Fuentes. The genus connects Soria with the Greek Titan. The type designation refers to the origin of Golamyo.

The holotype, MNS 2001/122, was found in a layer of Golmayo formation dating from the Hauterivien - Barremien. It consists of a partial skull without skull. Remained: a tooth, three spinal vertebrae, three pieces of the sacral leg, five tail vertebrae, two tailpieces of the tail, ribs, a chevron, right upper armbone, right prosthetic leg, a possible right earpipe, both bowel bones, both leg bones, a possible pubic bone and the left thigh bone. The skeleton was not related. It is found on an area of ​​seven by six meters. It is part of the Museo Numantino de Soria.


Soriatitan is about twelve meters tall, indicating a weight of about eight tons. The femur is about 102 centimeters long. The upper arm is raised 125 cm in length.

The descriptors identified eight distinctive features. These are automobomorphisms, derived unique features. The rear ribs have a pointed ledge in the center of the front of the shaft. The posterior tail vertebrae have large posterior joint protrusions that are longer than the front end to the backwards. The posterior joint vertebrae of the posterior tail vertebrae all have a groove in the outer side. There is a large rectangular ledge on the lower surface of the intestine of the intestine. The appendix of the intestinal leg is three times wider than front to back long. At the sitting leg, the shaft is as long as the branch to the pubic bone. At the upper arm, the deltopectoral comb on the outer side has two ridges protruding. The inner corner of the upper leg's head has two ridges.

The tooth is spoon-shaped and curved but free spit.


Within the Titanosauriformes Soriatitan is placed in the Brachiosauridae. A cladistic analysis found Soriatitan as a member of the Laurasiformes. There would be a close relationship with American forms such as Abydosaurus and Cedarosaurus, as evidenced by forward-facing spikes on the front middle tail. That would make Soriatitan the last known certain brachiosauride in Europoa. An invasion from North America was suggested through an Alaska farm.
