English: Figure 4. Aspiduriella streichani from the Middle Triassic of Rüdersdorf, Germany. (a) GZG.INV.90016, articulated skeleton preserving two arms and proximal segments of a third, exposing the dorsal side. (b) GZG. INV.90017, detail of oral plating of an articulated skeleton. (c) GZG.INV.90018, detail of proximal arm segments of an articulated skeleton in ventro-lateral view. (d) GZG.INV.90018, isolated vertebra in distal view. (e) GZG. INV.90019, isolated lateral arm plate in external (e1) and internal (e2) views. (f) GZG.INV.90018, proximal lateral arm plates of an articulated skeleton showing detail of spine articulations in lateral view. Abbreviations: AOS: adoral shield; APa: apical papilla; di: distal; do: dorsal; IR: ridge on the inner side of the lateral arm plate; LPa: lateral oral papilla; LR: lip-shaped ridge; MO: muscle opening; NO: nerve opening; SP: spur; TS: tentacle scale; VR: vertical ridge proximally bordering muscle opening; 1VAP: first ventral arm plate.
