| Caption: | A fossil specimen of Ludwigia extralaevis Quenstedt. A fossil ammonite. (Mollusca, Cephalopoda, Ammonoidea.) From fallen blocks on shore between Bearreraig Bay & Holm Island, Skye, Invernessshire (Skye), Scotland. |
| Description: | Ludwigia extralaevis is a member of the Superfamily: Hildocerataceae. Members are usually compressed and have a keel and sickle-shaped growth lines and ribs. Ludwigia has a stronger keel and is more evolute. British Geological Survey Biostratigraphy Collection number GSE 2946. An Upper Jurassic form from the Inferior Oolite, murchisonae zone of Skye. The Ludwigian fauna preceded the later Sonninian fauna. The Inferior Oolite is well developed in the Hebridean region and is very similar to that in England. It attains a maximum thickness in Skye (375 feet) and Raasay (600 feet) and represents a period of marine incursion of a warm sea. |
