| Caption: | A fossil specimen of Dicellograptus sextans exilis. A fossil graptolite. (Graptolithina.) Water of Deugh , Kirkcudbrightshire, Scotland. |
| Description: | Dicellograptus is a genus of graptolites that lived in the Middle and Upper Ordovician. This specimen was found at the Water of Deugh. British Geological Survey Biostratigraphy Collection number GSE 15112. It is a uniserial form with two reclined stipes and this specimen comes from the gracilis Biozone. Fossils such as Dicellograptus and other graptolites have been used in establishing stratigraphical time scales for the Lower Palaeozoic and have been used as a zone fossil since the mid-nineteenth century. Graptolites are colonial marine invertebrates now believed to have distant affinities to vertebrates. Fig. Mem.for Geology of Carrick and Doon Sheets 8W/8E, fig.5h. |
