| Description: | Glypograptus euglyphus is a graptolite from the Ordovician gracilis Biozone of the Southern Upland Terrane at Water of Deugh. British Geological Survey Biostratigraphy Collection number GSE 15113. It belongs to the Diplograptinae Subfamily and Diplograptidae Family. It is a scandent biserial form and has thecae with a gently sigmoidal curvature. As a genus Glyptograptus could be found from the Middle Ordovician to the Lower Silurian and had a worldwide distribution. Graptolites were free-floating forms that evolved a range of hydrodynamic strategies to remain suspended, long nemas developed to retard sinking, hooks, spines and nets formed to increase drag and the animals themselves (called zooids) may have helped the colony to move and possibly secreted gas or low-density fat to help the colony rise through the water.
