| Caption: | A fossil specimen of Olenellus lapworthi Peach. A fossil trilobite. (Arthropoda, Trilobita.) Roadside quarry, opposite Loch Awe, 3.5 miles south of Inchnadamph Hotel, Sutherland, Sutherland, Scotland. |
| Description: | Olenellus is a trilobite and is found in the Lower Cambrian. It is characteristic of 'Atlantic Province' (Europe, east part of North America, North Africa). British Geological Survey Biostratigraphy Collection number GSM 102270. It has a wide semicircular cephalon with genal spines pointing backwards. It has distinct furrows on the glabella and had large crescentic eyes. The thorax containes 14 segments and it has a small pygidium. This specimen shows the cephalon only and is from the Lower Fucoid Beds. The Cambrian Period from 600-500 million years ago saw a profusion of invertebrates coming into existence. Many had hard protective shells or skeletons. About half the known fossils in the Cambrian belong to the now extinct group of arthropods called trilobites. In length trilobites were from pin-head size to gigantic, up to 45 cm. long. Olenellus was of average size, up to 25 cm. Most trilobites were scavengers. |
