The name Spinosaurus means spine lizard because tall bones on its back supported a large sail.
Kid Decode: That sail made its silhouette instantly fossil-famous.
3. It Had a Tall Sail
Spinosaurus had long spines rising from its back, forming a sail-like shape that may have helped with display or other body functions.
Kid Decode: The sail was prehistoric show-off hardware.
4. It Had a Crocodile-Like Snout
Spinosaurus had a long narrow snout with cone-shaped teeth, useful for gripping slippery prey such as fish.

Kid Decode: Spinosaurus is where dinosaur science puts on water shoes.
9. Baby Spinosauruses Were Hatchlings
Like other dinosaurs, Spinosaurus hatched from eggs, and young babies can be called hatchlings.
Kid Decode: A hatchling Spinosaurus was a tiny start to a sail-backed giant.
10. Its Fossil Story Is Complicated
Some early Spinosaurus fossils were destroyed during World War II, so scientists have used later discoveries and comparisons to keep studying it.
