Monoporopollenites sp.

Figure 3.5

Material. Samples Pb-9136, Pb-8870, Pb-9138, Pb-8896, Pb-9147, Pb-8872, and Pb-9334, Palynology Laboratory, IGLUNAM.

Description. Monad pollen, heteropolar, radiosymmetric, amb subcircular. Monoporate, pore diameter 1.5–4 µm, with annulus of 1 to 2 µm thick. Exine tectate, collumelate, 1 µm thick, scabrate.

Dimensions. Diameter 15–39 µm, 19 specimens measured.

Comparison. Monoporopollenites sp. from Cuayuca Formation differs of Monoporopollenites annulatus (Jaramillo and Dilcher, 2001) because the Mexican specimens are scabrate instead of psilate.

Fossil record. The genus Monoporopollenites has been widely reported in Mexico, the U.S.A., and Central and South America since the late Eocene ( Tschudy, 1973; Leopold, 1974; Graham, 1975; Biaggi, 1978; Frederiksen, 1980; Graham, 1988, 1989, 1991; Jaramillo and Dilcher, 2001; Palacios and Rzedowski, 1993; Martínez-Hernández and Ramírez-Arriaga, 1999, 2006).
