The discovery was disclosed this Wednesday (7), through an article published in the journal PLOS ONE.

About 25 species of dinosaurs have been discovered in Spain

According to the Spanish website La Vanguardia, with this one, there are already about 25 species of dinosaurs discovered in the country. The research team says that identifying Portellsaurus as a unique species (named after the region in which it was discovered) provides crucial insight into the evolution of hadrosaurids in the Cretaceous period.

Hadrosaurids are a family of herbivorous dinosaurs, ornithopods, endowed with three toes, usually bipedal and of large or medium size, which stand out for their flat jaws, similar in shape to a duck's beak and a pelvic structure superficially similar to that of birds.
