Material. Samples Pb-9337, Pb-9340, Pb-8898, Pb-9141, Pb-9147, Pb-9136, Pb-9339, and Pb- 8896, Palynology Laboratory, IGLUNAM.
Description. Monad pollen, isopolar, radiosymmetric, amb triangular. Triporate, angulaperturate, aspidate pores, annulate, annulus with a 5.6 P m diameter. Exine tectate, granulate, 1.2 P m thick, scabrate. The granular infratectal structure gives a microreticulate pattern.
Dimensions. Equatorial diameter 26–37 µm, two specimens measured.
Comparisons. The size of the Casuarinidites sp. from the Cuayuca Formation is similar to that of C. granilabrata described by Srivastava (1972); however the exine of C. granilabrata is 2 µm thick.
Other occurrences. This genus has been reported in Mexico from the Oligocene San Gregorio Formation (Martínez-Hernández and Ramírez-Arriaga, 2006); Oligo-Miocene of Chiapas ( Biaggi, 1978). U.S.A. – Miocene, Massachussets ( Frederiksen, 1984); Paleocene, Alabama ( Srivastava, 1972).
