Predator and Prey
Near Cerro Condor in Argentina, paleontologists discovered both Piatnitzkysaurus and another dinosaur, Patagosaurus. Because Piatnitzkysaurus is a meat-eater and Patagosaurus is a plant-eater, the experts naturally speculate that Piatnitzkysaurus preyed upon the slower Patagosaurus.
Slow but sureSauropods like Patagosaurus may have been slow, but they had a few defensive tricks of their own. If size alone didn't scare off a hungry predator, this dinosaur might have lashed out with its whip-like tail, delivering a stinging blow to an attacker.
