It is the Early Cretaceous in South America, 112 million years ago, and these Tupandactylus imperator are ready to tear into the carcass of a recently deceased sauropod dinosaur. Tupandactylus was a member of a family of pterosaurs known as the Tapejaridae, which stand apart from other pterosaurs by virtue of their humongous fin-shaped head crests. Some of these pterosaurs may have been omnivores as likely to eat plant matter as meat, but others may have hunted relatively large prey like modern raptorial birds.
