What was discovered

At barely twelve years old, Mary Anning and her brother found in the cliffs of Lyme Regis the first complete skeleton of a large extinct marine reptile, which became the type specimen of the genus Ichthyosaurus. The find was one of the first compelling physical proofs that now-extinct species had once existed, and helped found palaeontology as a science.

What it led to

  • Founding of vertebrate palaeontology
  • Mary Anning's belated scientific recognition
