Living fossils : Brachiopods or Lamp Shells
Hi there Charlotte: here's your first challenge from Nanna. So.... we have Brachiopods, or Lamp Shells living in southern NZ, where you live. Cool eh? This is what the red ones look like, and the black ones look the same, but with more ridges on the shell. I haven't been able to find a picture of the black ones. The colour makes them easy to find on the beach, once you start looking. They are about the size of a 50c coin. But why a lamp shell? What kind of lamp was that? In ancient times we used lamps filled with oil that looked pretty much like these shells. I included the bottom picture so you can see how the lamp works. It has a wick of cotton or linen fibre and the fuel is olive oil. The closed in lamp is easy to carry without spilling the oil. Now take a peek at a side view of the brachiopod shell and you will see why it is called the lamp shell. So when you find some Brachiopods, either fossil ones in rocks or shells on the beach please sen
