Fig. 3 in A new pleurocystitid blastozoan from the Middle Devonian of the Eifel (Germany) and its phylogenetic importance

Fig. 3. Interpretative camera lucida drawings of the pleurocystitid blastozoan Regulaecystis testudineus sp. nov., Nims Member of the Junkerberg Formation (Eifelian, Middle Devonian), Prüm Syncline (Rhenish Massif, Germany). A. Paratype GIK−2277, abanal face showing the plate names (A1) and anal face showing the shape of the periproct and the organisation of the primary opening area (A2). B. Holotype GIK−2276, anal face showing the insertion of the ornamented stem (B1) and lateral view showing the strengthening of the thecal margins due to strong ornamentation in thick ridges and thick granules (B2). C. Abanal face of the paratype GIK−2278 showing the dense granulation. Cup and isolated plates of Stylocrinus tabulatus (Goldfuss, 1839) are preserved in the anal face. Plate names abbreviations follow Kesling (1967). Scale bars 5 mm.
