Fossil Oysters 3

Fossil Oysters - Deltoideum delta

This is the third in the series featuring fossil oyster shells. The photographs are of Deltoideum delta (also known as Liostrea delta) from the Upper Jurassic Period Kimmeridge Clay at Ringstead Bay, Dorset, UK. The most noticeable feature of this pair of matched valves is the way in which the outline shape differs from the examples already shown in Fossil Oysters 1 and Fossil Oysters 2. Here the shell has a basically regular almost tear-shaped outline in contrast to the others shown in the previous Postings. However, it has in common with them a number of smaller attached oyster shells. Again, two on the left valve (part of the settlement substrate); and one on the right valve which had settled upon it in turn.
