Scientists identify new dinosaur species from footprints in Brazil

Brazil's geological service on Thursday announced a new species of dinosaur, a speedy animal that lived in the desert during the early Cretaceous period. The new species, called Farlowichnus rapidus, was a small carnivorous animal about the size of a modern-day seriema bird, or about 60-90 cm (2-3 feet) tall, according to researchers. The discovery was published in scientific journal Cretaceous Research.
