Scientists discover 150 million yrs old dog-sized dinosaur species
Scientists have discovered a new species of dinosaur, that was dog-sized and roamed in today's United States around 150 million years ago. The species named, 'Enigmacursor mollyborthwickae' was about the same size as a Labrador retriever, with its tail equal to nearly half of its total body length. The study's co-researcher said that the dinosaur was "quite a speedy runner."
