Starvard.Starvard Field Guide
Ten giants (and two little ones) from the age of reptiles, in big beautiful pictures, with the facts that matter.
Dinosaurs ruled the land for more than 160 million years, far longer than humans have existed. Everything on this page was rebuilt from fossils by artists working with scientists. The bones and muscles come from real evidence. The colors are educated guesses, and honest ones: nobody has ever seen a living dinosaur, except the ones that still fly past your window. Birds are dinosaurs too.
The most famous dinosaur of all, and the star of the Smithsonian fossil hall. Its bite was one of the strongest of any land animal ever, strong enough to crush bone. For all that power, its arms were tiny, with just two fingers each.
A giant shield of bone protected its neck, and three horns guarded its face. Its mouth ended in a sharp beak like a parrot, perfect for snipping tough plants. T. rex and Triceratops fossils are often found in the same rocks, hunter and hunted together.
The movie monster was oversized. A real Velociraptor stood about as tall as a turkey, and it wore feathers. Its weapon was a curved, switchblade claw on each foot, kept sharp and raised off the ground as it walked.
Two rows of bony plates stood along its back, and four spikes armed its tail (scientists really do call the tail spikes a thagomizer, after a cartoon). For an animal the size of a bus, its brain was famously small.
The longest meat eating dinosaur we know, and the strangest. A huge sail rose from its back, its jaws were shaped like a crocodile, and it hunted in the rivers of North Africa, more at home in the water than any giant predator since.
Most long necked dinosaurs held their heads level with their backs. Brachiosaurus stood tall instead, because its front legs were longer than its back legs, lifting its head high into the treetops like a giraffe.
One of the longest animals ever to walk the Earth, with a tail like a whip that may have cracked like a bullwhip. A famous Diplodocus skeleton nicknamed Dippy has been copied and displayed in museums all over the world.
A living tank. Bony plates armored its back, its eyelids were bone, and its tail ended in a heavy club that could swing with bone breaking force. Even T. rex had to think twice.
The long tube on its head was a built in trumpet. Air pushed through the crest could sound deep, carrying notes across the herd. It walked on four legs and could rear up on two to reach higher leaves.
Half dinosaur, half bird, and the fossil that changed science. It had flight feathers and wings, but also teeth, clawed fingers, and a long bony tail. Birds are living dinosaurs, and Archaeopteryx is the bridge that shows it.
