About Kentrosaurus

Kentrosaurus was a small cousin of Stegosaurus from Africa. It had plates on its front half and long, sharp spikes on its back half and tail.

Kentrosaurus was a stegosaurid from the Late Jurassic Tendaguru beds of Tanzania, known from more than a thousand bones from many individuals. Narrow plates on its neck and back gave way to paired spikes along the hips and tail, plus a long spike on each shoulder.

Did you know?

  1. Kentrosaurus had more spikes than Stegosaurus β€” including one on each shoulder!
  2. It was about as long as a car.
  3. Its tail could swing in a wide arc, like a spiky whip.
  4. It lived in Africa, in what is now Tanzania.
  1. Computer models of its tail by Heinrich Mallison suggest Kentrosaurus could swing its spiked tail through a wide arc at speeds fast enough to break bones or cause deep wounds.
  2. Hennig originally placed the long spike over the hip, but later studies favour the shoulder; a few researchers still argue the evidence is not conclusive.
  3. Much of the original Kentrosaurus material was destroyed during the Second World War, but a mounted skeleton survives at the Museum fΓΌr Naturkunde in Berlin.
  4. Differences in thigh bones from the Tendaguru quarry may reflect two body types, which some researchers interpret as males and females.
