Stegosaur diversity

Stegosaurs are known for the rows of plates and spikes on their backs and tails (which differed between species).

Evidence suggests the plates contained networks of blood vessels that could have been for regulating body temperature. Skin over the plates could have been coloured for display or to help differentiate between species or bluff predators.

Examples of stegosaurs include:

  • Wuerhosaurus homheni – China, 140–100 million years ago
  • Huayangosaurus taibaii – China, 168–161 million years ago
  • Kentrosaurus aethiopicus – Tanzania, 156–151 million years ago
