Etymology
Dogger in geology came into English from German geologists who used Dogger for the 'middle' part of the Jurassic, probably after local iron-rich rock layers with a similar name. So dogger now means the middle Jurassic rock layers, which helps you remember it as the ironstone-rich part of that time.
