Which theropod dinosaur was not a meat-eater?

 

 

                           Segnosaurus is an odd dinosaur that scientists have found difficult to classify. It seems to be related to the meat-eating dinosaurs, but it would not have been able to run fast and does not have the right kind of teeth for a meat-eater. Because the front legs of Segnosaurus have powerful claws, it has been suggested that this dinosaur fed on termites, like the modern anteater. Alternatively, Segnosaurus could have been a plant-eating dinosaur although it would have been the only theropod to do this.
