This is part four of the geology tour. We are walking along the timeline and we’ve now got to the case reading Devonian. In here we have a fossil fish. It’s not the earliest fish, there were quite a lot of fish before this, but you wouldn’t really recognise them easily. For a start they didn’t have jaws: they were strange sort of vacuum-cleaner like things that just sort of floated along the sea floor sucking up anything they could eat but by the time you get to the Devonian, this is about four hundred million years ago, suddenly we have a huge diversity of different types of fish which you would recognise. They had scales, they had teeth and jaws, they had bones and most of them weren’t armour-plated like the earlier ones had been.
There are many places, particularly in Scotland today, where we can find these fossil remains and the north of Scotland is famous for it. The one you see in here is from a place called Achanarras Quarry which is one of the most important early fish localities in the world.
