Stegosaurus Baby

No. 301729

by Safari Ltd

Stegosaurus was a large plant-eating dinosaur that lived during the Upper Jurassic (155-150 million years ago) in what it now western North America. It had an unusually small head and very short front legs. Stegosaurus was armed with a spiked tail and had two rows of large bony plates on its back.

  • Scientific Name: Stegosaurus, meaning ‘covered lizard’ for the bony plates that covers its back.
  • Characteristics: Very young Stegosaurus were quite similar to the adults except that their heads are relatively larger, and their tail spikes and back plates were smaller. It is possible that the babies were protected from predators by the adults, and so didn’t need their tail spikes to ward off attacks.
  • Size and Color: This model is 3 inches long and 1.75 inches high. Similar to the adult, it has a red-brown back and yellow belly and legs to allow it to blend into the background.

Although the first Stegosaurus skeletons were collected in the 1870s, the first baby skeletons weren’t described until 1982. These skeletons show that although the young Stegosaurus resembled the adult in most ways, their back plates were poorly developed, as shown in this model.

We once thought that the bony plates on their back were also for protection, but we now believe that they were more likely used to make themselves look bigger while combatting other Stegosaurus, or perhaps to attract potential mates the way a male peacock uses its tail to attract a hen. Since baby Stegosaurus are too young to worry about such things, it makes sense that their plates are still so small.
