BUENOS AIRES, Oct. 25 (Xinhua) -- Argentina Monday displayed fossils of a newly discovered dinosaur species that lived 228 million years ago in the region.
The fossils, which were found 16 years ago in Luna Valley in western Argentina, were exhibited by Argentina's San Juan Province and the Natural Science Museum of the San Juan National University.
San Juan Province Governor Jose Luis Gioja and Oscar Alcober, director of the Natural Science Museum, attended the ceremony to exhibit the fossils of the species, a predator 2 meters long and 1.5 meters high called Sanjuansaurus gordilloi.
The fossils, discovered by fossil preparator Raul Gordillo in 1994, included a mouth bone, the spine from the first vertebra in the neck to almost the end of the tail, bones from the chest and the hand.
The Sanjuansaurus is recognized by international scientific circles as a new member of the Herrerasaurus family, which includes other species found in the same zone.
Alcober said that the Sanjuansaurus was probably the one which ran fastest in this family.
"It walked with its back legs, which allowed it to have free its front legs to attack its enemies and victims," Alcober said.
