"It's one of the smallest on record in Portugal and probably the smallest of herbivorous dinosaurs, because it belongs to one of the smallest groups at a global level and because it probably wasn't yet an adult," researcher Fernando Escasso told Portuguese Lusa News Agency.
After studying the findings of studies made in 1999 and travelling to America to observe fossils of this era, the researchers from the National History Society of Torres Vedras, the University of Lisbon and the University of Madrid, classified the new species of dinosaur, Xinhua news agency quoted Lusa as saying.
