| Big Texas Pterosaurs
The Texas skies of the late Cretaceous are ruled by the largest flying reptile in all of earth's natural history. With a wingspan of nearly 40 feet (12 meters) Quetzalcoatlus is more like a modern jet fighter than a flying Mesozoic creature. The skies become turbulent when the graceful glider, Quetzalcoatlus, invades airspace dominated by smaller Pteradons, who themselves posses a 22 foot (6.7 meter) wingspan. The Pteradons chase and circle the larger Quetzalcoatlus, hoping to drive the unwelcome drifter beyond their territory. |

| Sounds of Southern Waters One hundred ten million years ago, the ocean waters surrounding Australia thrive with marine life. Fish, squid and other sea creatures that populate these southern waters have become the primary food source for a new type of marine reptile called Plesiosaur (near lizard). The Plesiosaur, Woolungosaurus, has a distinctively long neck that stretches out beyond its body, allowing the animal’s head and jaws to quickly snatch the unsuspecting creatures in its path. With four flippers independently powered by strong muscles, this 33-foot (10-meter) long carnivore swims with impressive speed and agility. A local pod of Woolungosaurs dart through Australian waters of the early Cretaceous, exhibiting a range of calls and cries that reverberate through their underwater territory. Some of the vocalizations may be meant to reveal the location of nearby schools of fish to their fellow hunters. Other calls could be used as a means to identify individual members of the pod as they navigate the depths of the ocean. |
