National Geographic : 2008 Apr
Goodwin's and Homer's hypoth esis that Dracorex represents a juvenile Pachycephalosaurus was presented at the Society of Vertebrate Paleontology meeting in late October 2007, after our December feature on extreme dinosaurs had already gone to press. Regardless of its age at time of death, however, the creature merits a place in our gallery of Mesozoic oddities. When I saw the image of the Masiakasaurus speeding through shallow water, my first thought was the mouth of a gharial, the croclike reptile from the river Ganges. It feeds on fish and has the same pro truding teeth as the creature shown in your magazine. FRANK LENICH Bayreuth, Germany Are you sure you have your facts straight? That Masiaka saurus sure looks like one of my former bosses. EARLE KOLBE Alcoa, Tennessee It surprises me that paleontolo gists don't ask military people about dinosaur survival tactics. The short arms of the Carno taurus suggest a scavenger more than they do a perfect killing machine. If one bit me, I'd just whip my big tail around and knock him off. Modern carnivores like the African big cats use claws on long arms and big teeth for killing. One would think a multiple assort ment of weapons would be needed to take down these big cattle. In the case of the duck billed Parasaurolophus walkeri, wouldn't an acoustics check of that tube be a way to check it out for hornlike noises? Musi cal instrument makers would probably bend over backward to help prove or disprove these claims.
