Scolecopteris cf. parvifolia Millay, 1979

( Fig. 8C View FIG )

This may represent a second type of fertile parts with large pinnules (6 to 8 mm long and 2-2.5 mm wide), bearing two rows of up to 14 synangia, each consisting of 4 to 5 sporangia. The lamina is thin (200 µm) without a well-marked palisade or spongy tissue; sporangia (up to 0.9 mm long) are borne on a short vascularised pedicel(250 µm broad) and they are united around this pedicel in their proximal region. The sporangia tips are solid and bluntly pointed. This fertile structure is similar to that of S. parvifolia as defined by Millay (1979: pl. 10, fig. 66) from the Pennsylvanian American coal balls.
