Masculostrobus sp. 1

Pl. 8, Fig. 11

S t r a t i g r a p h y: Peruc-Korycany Formation, Cenomanian, Upper Cretaceous.

M a t e r i a l s t u d i e d: GBA_78.

O c c u r r e n c e: Maletín.

D e s c r i p t i o n. Specimen no. GBA_78 (Pl. 8, Fig. 11) is a 56 mm long and 17 mm wide microsporangiate (pollen) cone of longitudinal ovate shape in its apical and basal parts. Its surface is covered by helically arranged rhombical to hexagonal microsporophyls which are very subtle (2× 2 mm). On the right side of the specimen, there are peltate sporophylls with elongated needle-like mucro.

D i s c u s s i o n. The microsporangiate cone Masculostrobus sp. 1 differs from the microsporangiate cone Masculostrobus sp. 2 in having longitudinal ovate shape with larger rhombical to hexagonal microsporophylls. Both species of the genus Masculostrobus differ from the genus Conago in having considerably smaller and densely arranged sporophylls.
