Fig. 15 in Taming an ichnotaxonomical Pandora's box: revision of dendritic and rosetted microborings (ichnofamily: Dendrinidae)

Fig. 15. Dictyoporus nodosus Mägdefrau, 1937. A–B. Overview and close-up of the holotype in an Upper Cretaceous belemnite from Misburg, Germany. C. Specimen with lower degree of anastomosis, but better defined centre; same belemnite as holotype of Calcideletrix flexuosa Mägdefrau, 1937. D. Large specimen in a shell of the bivalve Inoceramus Sowerby, 1814 from the upper Campanian of Kronsmoor, Germany, showing a combination of open channels and endolithic tunnels. E–F. Incipient and transmission light micrographs of a pyritised specimen in an aptychus from the lower Campanian of Höver, Germany, showing surficial channels, a deeper tier of endolithic tunnels and variability in tunnel diameter. G. Holotype of junior synonym Cliona fenestralis Elias, 1957, preserved as natural cast in a Late Mississippian brachiopod (currently lost; reproduced from Elias 1967: pl. 40, fig. 2; scale bar derived from original description). H. Holotype of junior synonym Cicatricula retiformis Palmer & Palmer, 1977 on a slab of Ordovician hardground, displaying readily anastomosing channels with a decrease in mesh size towards the periphery. I. Holotype of junior synonym Dictyoporus garsonensis Elias, 1980, preserved in an Upper Ordovician rugose coral.
