Figure 4 in Glide-leflection symmetly in deutelostomes: an evolutionaly pelspective

Figure 4. Details of calcified rings in the notochordal sheath of Chimaera monstrosa ZIN 34419. A* B* the pectoral trunk region just posterior to the synarcuale (also shown in Fig. 3B and Supporting Information* Models S2* S3). C* D* the tail region just anterior (C) and just posterior (D) to the beginning of the anal fin (also shown in Supporting Information* Model S4). Asterisks marks the dorsal suture between the left and right halves of the rings and commissures. A* C* D* schemes of ring halves in posterior view; the planes of mirror-reflection symmetry are indicated by green lines. B* left-posterior view of CT-scan-based 3D reconstruction of spiral commissures between the rings; the commissures are painted in pink (left part) and blue (right part); calcified parts of basidorsal (BD) and interdorsal (ID) elements of the neural arches are shown for orientation.
