Figure 16. Cross sections (A–D; all × 1.5) and ontogenetic trajectories (E–H) of Cymaclymenia formosa n. sp. from the Anti-Atlas of Morocco. (A) Paratype MB.C.22649.3 (Korn 2009 Coll.) from Lambidia. (B) Paratype MB.C.22646.1 (Korn 2009 Coll.) from Madène el Mrakib. (C) Paratype MB.C.22646.2 (Korn 2009 Coll.) from Madène el Mrakib. (D) Paratype MB.C.22646.3 (Korn 2009 Coll.) from Madène el Mrakib. (E) Conch width index (ww / dm). (F) Umbilical width index (ww / wh). (G) Whorl width index (uw / dm). (H) Whorl expansion rate (WER).
