A spiky dinosaur beside a tree

Shown in profile, the dinosaur stands with its head extended toward the trunk of a tall tree on the right. Spikes run along its back, and tufts of grass, scattered pebbles, and other small plants cover parts of the ground around it. The simple landscape remains focused on the animal and tree.

Curious facts about dinosaur spikes

Spikes and other bony structures could serve different purposes in different dinosaur groups, including defense, display, or recognition between members of the same species. Their shape and arrangement are important clues when paleontologists compare fossils. A dinosaur's skull, teeth, hips, and limbs usually provide stronger evidence about its diet than spikes alone.

Possible colors in the prehistoric landscape

  • Dinosaur skin: the exact species and colors are uncertain, so earthy brown, olive, tan, or muted gray are plausible natural choices
  • Back spikes: they may have matched the surrounding skin or appeared darker or lighter, as display structures do in some living animals
  • Eyes and claws: eyes could use a dark pupil with a brown or amber iris, while claws may be horn-colored, brown, or charcoal
  • Tree trunk: bark commonly ranges from pale gray and warm tan to deep brown
  • Grass, pebbles, and small plants: varied natural greens with stones in gray, beige, brown, or rusty shades
Questions and answers

Questions and answers

Does a row of spikes prove that a dinosaur was a predator?
No. Both plant-eating and meat-eating dinosaurs could have prominent body structures. Teeth, jaws, and fossilized food evidence are more useful for identifying diet.
What were dinosaur spikes made of?
Many were built around bone and may have had an outer covering of keratin, the tough material found in modern claws and beaks. The covering itself rarely fossilizes.
How can scientists identify an unknown dinosaur?
They compare the shapes and proportions of fossil bones with well-studied specimens. Where the fossils were found and the age of the surrounding rock also provide useful evidence.
