The Site from the Sky

The Site from the Sky. . From the air, you can see the tracks of two sauropod dinosaurs walking side by side along the ancient lakeshore. The discovery that some types of dinosaurs lived in large herds like modern animals happened because of parallel tracks identified here in the 1930s. , Tracks of meat-eating dinosaurs radiate in all directions, indicating that carnivores roamed the lakeshore as solitary hunters. Large carnivores are generally less common than large plant-eaters but roughly equal numbers of footprints occur at this site. Perhaps meat-eaters were faster and more active than plant-eaters? , Research continues to unfold the intriguing story of ancient life at Dinosaur Lake. , Captions: , The neatly fractured blocks you see along the river are the result of "Jointing"-when hard but brittle limestone buried deep in the earth is stressed to the point of breaking. , Some layers of limestone show clear trackways of sauropods while others are heavily trampled with many overlapping footprints. The large, rounded prints of these big plant-eaters show that they were generally lumbering west along the lakeshore, often in groups or herds.
