O is for Oysters. The shells of oysters in particular. My main research interest for the last 45 years is the macroscopic variations shown in oyster shells. Here is a selection of images illustrating several types of oysters and detailed shots of various features.

  1. I am interested in your thoughts on the origin of oyster shells on Swansea Bay. Is it correct to think that there are few oysters living, at the present time, in the bay and therefore the shells are largely from earlier times, especially when they were extensively farmed, mainly in the 19th century?
    Are at least some of the heavily blackened and worn shells reworked from the Holocene clays, below the present day sediments, which are exposed on the beach, near St. Helens etc.
    Note that geologists normally regard blackened and worn fossils as a usefull indicator of reworking from earlier sediments.

  2. Dare I ask what you have discovered from your long study into variations in the shells? Are they an indicator of water quality? That’s not a rhetorical question, it’s a guess. I knew a zoology student 25 years ago (at Cardiff) who studied oysters and that’s what she said.

  3. Hi, Emma. The oyster shell variations that I have been looking at are not so much a reflection of water quality, as far as I know, as of variations in the substrate and other local environmental conditions. I was looking at them to see if it is possible to determine where oysters found during archaeological excavations have come from, suggesting trade routes, farming and so forth. A very narrow area of specialism.
