Fig. 33. A in Taming an ichnotaxonomical Pandora's box: revision of dendritic and rosetted microborings (ichnofamily: Dendrinidae)

Fig. 33. A. Evolutionary trends in dendrinid microborings, considering the known range (based on certain end members only) of the various ichnospecies (light grey) and the number of ichnospecies making their first appearance (dark grey). Numbers are per period, except for the Paleocene to Pleistocene (global series). Relevant evolutionary radiations and extinction events are indicated. B. Same graph for all microbioerosion ichnospecies, but based on actual records only (data from Wisshak et al. 2008; numbers per period). C. Ichnodiversity curve for all bioerosion ichnogenera based on range data (data from Buatois & Mángano 2016; numbers per global series).
