New dinosaur uncovered in Brazil
Scientists in Brazil say they have uncovered a new species of dinosaur [Unaysaurus tolentinoi]. The creature, identified from fossils, is thought to have lived more than 200 million years ago, making it one of the earliest dinosaurs known to science. The research team, from the University of Rio de Janeiro, says there are strong similarities with its creature and remains discovered in Europe. This lends weight to the view that the world's landmasses were once joined as a single continent in Triassic times.
