Spinosaurus Anatomy in 3D: Skeleton, Organs and the Giant River Hunter

Spinosaurus is the longest meat-eating dinosaur we know of, a giant with a tall sail on its back that hunted fish in rivers. In the 3D Dinosaur Anatomy simulator you can spin it around, look inside and explore its skeleton.

The Spinosaurus fossil skeleton

The Spinosaurus skeleton has a long, narrow, crocodile-like skull with cone-shaped teeth for gripping fish. Tall spines grew up from its backbone to hold up the sail, its bones were dense and heavy, and its tall tail may have worked like a paddle in water.

Interesting facts about Spinosaurus

  • It is the longest known meat-eating dinosaur, at around 14 m.
  • The spines that held up its sail were well over a metre tall.
  • Its cone-shaped teeth were good for gripping slippery fish.
  • The first Spinosaurus fossils were found in Egypt and were destroyed in a bombing raid during the Second World War.
  • Its dense bones and paddle-like tail suggest it spent a lot of time in water.

Spinosaurus anatomy questions

Was Spinosaurus bigger than T. rex?

It was longer, at about 14 m, but it was more lightly built, so T. rex was probably heavier.

What did Spinosaurus eat?

Mostly fish, caught in rivers with its long jaws and cone-shaped teeth.

What was the sail for?

Probably for display, to show off to rivals and mates, though scientists are still debating it.

Where did Spinosaurus live?

In North Africa, in what are now Egypt and Morocco, about 99 to 93 million years ago.
