Tyrannosaurus rex, one of the most feared predators in the age of dinosaurs, may have been built for endurance, not speed. A paper published Wednesday in the scientific journal PLOS ONE takes recent research on how mammals move and applies it to dinosaurs. "That, coupled with body mass, can tell us a lot about speed," said Larsson. The paper says the T. Rex was likely an efficient walker reaching top speeds of 20 km/h rather than 70 km/h as earlier research has proposed. Recalibrating with focus on body mass"What we wanted to do was recalibrate … dinosaur speed using some really cool new papers that have come out using mammals, especially really large mammals."
