Fig. 6 in Evidence of external gametophores in puzzling Late Triassic-Early Jurassic dasycladalean green algae

Fig. 6. Dasycladalean alga Chinianella ellenbergeri (Lebouché and Lemoine in Granier and Deloffre, 1994) Granier, Masse and Berthou, 1994, emend. nov., upper Sinemurian (Lotharingian), Canders, 2.4 km E of Fontcaude, (S France). A. LM-DiSTAR/BA.577.16, n. 065, oblique section of a weakly mineralized specimen showing intusannulation. B. LM-DiSTAR/BA.577.21, n. 114, axial section, notice the irregular inner contour. C. LM-DiSTAR/ BA.577.24, n. 117, axial section of a weakly mineralized specimen showing intusannulation. D. LM-DiSTAR/BA.577.28, n. 126, oblique section of a weakly mineralized specimen with intusannulation. E. LM-DiSTAR/BA.577.4, n. 003, oblique section of a strongly mineralized specimen, note the regular contour of the inner cavity, interverticillar cavities sometimes communicate with the central cavity by mean of a small pore (see arrow). F. LMDiSTAR/BA.577.9, n. 018, oblique section showing the annular and vertical channels. G. LM-DiSTAR/BA.577.10, n. 024, transverse-oblique section, a possible gametophore looks attached to primary lateral (see arrow). H. LM-DiSTAR/BA.577.8, n. 014, transverse-oblique section showing the annular and vertical channels. I. LM-DiSTAR/BA.577.15, n. 054, transverse-oblique section, note the annular channel with scalloped surfaces in the proximal sleeve and the calcareous shield, respectively.
