Fig. 11 in Taming an ichnotaxonomical Pandora's box: revision of dendritic and rosetted microborings (ichnofamily: Dendrinidae)

Fig. 11. Calcideletrix flexuosa Mägdefrau, 1937. A–C. Holotype in an Upper Cretaceous belemnite rostrum from Misburg, Germany. Close-up in B illustrates anastomosis and two potential points of initial entry (arrows). Close-up in C shows peripheral ramification. D–F. Respective SEM views of an epoxy casts of the holotype of junior synonym D. brachiopodicola Hofmann, 1996, illustrating the very close morphological resemblance of the trace in a belemnite vs a brachiopod substrate. G. Natural casts in a Devonian brachiopod with several C. flexuosa (original of Clarke 1908: pl. 10; damaged since original publication). H. Another silicified cast in a Devonian brachiopod shell (reproduced from Clarke 1908: pl. 11, fig. 2).
