Dapedium (Fish)

Fossil Favourite Stamp
Triggerfish, a distant relative of our fossil fish.

Fish in shining armour!

  • Most of the fossil fish on the Jurassic Coast are very different from our ‘modern’ fish because they were covered in armoured scales. These scales didn’t rot, creating a perfect fish-shaped fossil like this one.
  • This species is called Dapedium and it grew up to 40cm long.
  • Dapedium’s tail was short and stout, providing the power for a sudden change in direction while the fish was swimming.
  • The teeth of Dapedium are small and peg-like, probably to enable the fish to bite through the shells of its prey.
  • See this fantastic fish at Lyme Regis Museum.
