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.

About winderjssc

I have a background in ecological studies in both the museum and the research laboratory. I'm passionate about the natural world right on my doorstep and enthusiastic about capturing what I see through photography, wanting to open the eyes of everyone to the beauty and fascination of nature. I am author of Jessica's Nature Blog [https://natureinfocus.wordpress.com]. I have also extensively researched macroscopic variations in oyster and other edible marine mollusc shells from archaeological excavations as a means of understanding past exploitation of marine shellfish resources. I am an archaeo-malacological consultant through Oysters etc. where I am publishing summaries of my shell research and other oyster related topics [Oysters etc. at https://oystersetcetera.wordpress.com]. Photographic Salmagundi [https://photosalmagundi.wordpress.com] is a showcase of photographs and digital art on all sorts of subjects - not just natural history. P.S. The current profile picture was taken in 2015 at Whiteford Sands in Gower where I am kneeling to take pictures of an ancient buried tree trunk emerging from the peat for the first time after submersion by rising sea levels about 6000 years ago.
