Unable to fly or walk, Hesperornis needed to be wary of predators: sharks and plesiosaurs at sea, dinosaurs and pterosaurs on land.

Amazing 3D Canyon Flight Screensaver allows you to fly through photo-realistic three-dimensional canyon full of ancient pterosaurs.

Pterosaurs, also sometimes referred to as pterodactyls, dominated the skies in the Mesozoic Era, 220-65 million years ago.

The fossil remains of the first flying vertebrates, the pterosaurs, have intrigued paleontologists for more than two centuries.

Scientists have long assumed that pterodactyls, also called pterosaurs, flew just like birds, and launched themselves using their hind legs.

Perhaps the least controversial assertion about the pterosaurs is that they were reptiles.

Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight.

Instead, he says that pterosaurs needed all four limbs for liftoff.

The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings.

Pterosaurs are flying reptiles that lived at the same time as dinosaurs, between 210 million and 65 million years ago
