Washington, June 23 (ANI): A team of paleontologists has claimed to have discovered the largest carnivorous dinosaur tooth in Spain till date.

The features and size of the 9.83cm tooth provide key information needed to identify its former owner.

The researchers are in no doubt that it was a large, predatory, carnivorous dinosaur (theropod) belonging to the Allosauroidea clade (one of the branches of the phylogenetic tree), a group that contains large carnivorous dinosaurs measuring between six and 15 meters.

"Given the great variations between the teeth of different kinds of allosauroids, it would be prudent for us to assign this fossil to an indeterminate Allosauroidea," said Luis Alcala, one of the researchers involved in the study.

The tooth, found by local residents in Riodeva, Teruel, in the Villar del Arzobispo Formation, has been compared with other samples from the Allosauroidea group from the Iberian Peninsula - in particular with a large tooth from Portugal (measuring 12.7cm) and another belonging to an Allosauroidea indet in Spain, until now described as the largest in Spain at 8.27cm.

According to the paleontologists, "the presence of a large Allosauroidea is a great addition to the faunal record of the dinosaurs described in the Villar del Arzobispo Formation in Riodeva."

Plant-eating dinosaur groups (phytophages) discovered in the deposit to date have been identified as sauropods, stegosaurids and basal ornithopods (from tooth remains and a complete rear leg).

"Now the carnivorous dinosaurs are also represented, at least by two medium-sized theropods and a large predator belonging to the Allosauroidea clade," said Alcala.

Carnivorous dinosaurs grew new teeth over their lifetimes, which increase the likelihood of finding them.

In this case, the condition of the crown of the tooth found (without any reabsorption surfaces) indicates that it was not a discarded tooth.

The palaeontologists hope to discover the remains of this large predator, which could have attacked Turiasaurus riodevensis, the 'European giant'. (ANI)
