Dinosaurs and the Expanding Earth

BRACHIOSAURUS AND CERATOSAURUS

The carnivorous Ceratosaurus snarls at the larger plant eating Brachiosaurus frightening a small flock of flying reptiles called Rham-phorhynchus. This is a contest of giants. Although the Ceratosaurus is large, with a mass as great as one of today’s elephants, the Brachiosaurus is even larger at about 80 tonnes, twenty times more massive than a large elephant.

Brachiosaurus was one of the biggest land animals to have ever lived. There is a complete mounted Brachiosaurus skeleton with its head 13 metres above the ground in the Natural History Museum in Berlin. With its amazing height Brachiosaurus was able to strip the leaves and fruit from the highest trees.

Ceratosaurus was a large bipedal dinosaur similar to Allosaurus. Ceratosaurus had strong grasping hands, a short muscular neck and large meat-eating teeth. It was large with a length of 7-10 metres.


Both Brachiosaurus and Ceratosaurus lived in North America and Africa in the Late Jurassic time about 150 million years ago. They were able to wander freely between the two continents since the continents had not yet split and moved apart at that time.

The 1990 painting by John Sibbick is sensibly done. The Ceratosaurus looks as though it might attack the Brachiosaurus, but many dinosaur experts believe it unlikely that a lone Ceratosaurus would attack such a massive animal as a Brachiosaurus. It seems more likely that a small baby, or a old and dying Brachiosaurus would be a more likely source of food.

Perhaps the Ceratosaurus and the Brachiosaurus have inadvertently stumbled into each other and after much growling and stamping they will gradually move further apart to a safe distance.
