| Caption: | A fossil specimen of Pecten textilis Goldfuss. A fossil bivalve. (Mollusca, Bivalvia.) On shore 0.5 miles north-east of Dunrobin Castle, Golspie, Sutherland, Scotland. |
| Description: | Pecten has a subcircular, inequivalve shell, the right being rounded and the left flat, each valve has strong radial ribs for ornamentation. They have a large centrally placed muscle scar, contraction of which expelled sea water and so provided propulsion to allow Pecten to swim and possibly avoid predators. British Geological Survey Biostratigraphy Collection number GSE 3326. Pecten are scallops which lie free on the sea floor and can swim by rapid clapping of their two valves (shells). They are suspension feeders extracting food particles from circulating water by means of ciliary and trapping mechanisms. This example is from the Lower Lias of Lower Jurassic age from near Golspie in east Sutherland. Here, the Dunrobin Bay Formation consists of 72 metres of argillaceous deltaic sediments with 22 metres of soft white quartzose sandstone followed by 18 metres of dark micaceous, often marine shales. |
