Little Torosaurus is a young Torosaurus.
He was seen fighting a pair of Dromaeosaurus and the adults try to stop them from getting the youngster. In morning, it had become apparent that the little Torosaurus lost his fight with the predators - the carcass mauled. A Didelphodon appears and scavenges on the carcass.
