A 115-million-year-old fossil belonging to a previously unknown dinosaur species, now known as Aratasaurus museunacionali, was presented in Brazil to the public on Friday.

According to researchers, the individual was a juvenile theropod, which could have reached 3.12 meters in height and weighed up to 34.25 kilograms.

The fossil was found in Brazil's northeastern state of Ceara in 2008. A visual construct of the animal was formed after eight years of microanalysis of the bone fossil.

Archaeologists said the new dinosaur was related to the zuolong species that lived during the Late Jurassic period in northwest China's Xinjiang Uygur Autonomous Region.
