1B6F87DAFFDEFFC83B3CB85A528DF978.taxon	discussion	Discussion. Cycadolepis is used to name the set of bracts that likely surrounded the reproductive structures of some Bennettitales and detached with floral maturity (McLoughlin, 2017). The species C. mexicana Wieland has been reported from the Jurassic of Mexico, and has the same shape, size, and presence of hairs as the specimen described in the present work (Figure 3 C). However, the fragmentation of the specimen only allows proposing an affinity with this species. This genus has a cosmopolitan distribution throughout the Mesozoic (Beheresmeyer and Turner, 2022).	en	León, María Patricia Velasco de, Martínez, Erika Lourdes Ortiz, Barragan, Miguel Angel Flores, Madrid, Diana Silvia Guzmán, Martinez, Pedro Christian Martínez (2024): New records of Bennettitales and associated flora from the Jurassic of the Cualac Formation, Mexico.

1B6F87DAFFDDFFCD3B0DBA745450FA20.taxon	description	Description. Impressions and compressions of oblanceolate to lanceolate, even elliptic, leaflets 7 – 26 cm long and 2 – 8 cm wide, margin entire, thick midvein tapering towards the apex measuring 3 – 0.7 mm between eight to 11 anastomosing secondary veins. Mucronate, acuminate, acute, or rounded apices (Figure 5 A-B). The cuticle has quadrangular to rectangular epidermal cells 3 – 5 μm wide and 8 – 15 μm long, the largest are 9 – 25 μm wide and 23.2 – 69.4 μm long. Slightly undulate cell walls with a thickness of 0.5 – 1.5 μm, and the thickest of up to 9 μm (Figure 5 C-E). Sunken stomata without apparent arrangement, stomatal opening is 0.5 – 3 μm wide and 2 – 5 μm long, from paracytic to anisocytic. Rounded to oval stomata 10 – 13 μm wide and 10 – 20 μm long in some specimens. Thin, 1 – 2 μm wide and 1.5 – 3 μm long, and thickened, 4 – 7 μm wide and 6 – 10 μm long, guard cells. Anisocytic subsidiary cells 2.5 – 4.2 μm wide and 5 – 8 μm long (Figure 5 F). Simple trichomes in the midvein 0.4 μm wide and 0.3 – 0.5 long (Figure 5 G).	en	León, María Patricia Velasco de, Martínez, Erika Lourdes Ortiz, Barragan, Miguel Angel Flores, Madrid, Diana Silvia Guzmán, Martinez, Pedro Christian Martínez (2024): New records of Bennettitales and associated flora from the Jurassic of the Cualac Formation, Mexico.

1B6F87DAFFDDFFCD3B0DBA745450FA20.taxon	discussion	Discussion. When analyzing the morphological characters of this species, differences are mainly observed in the venation patterns, and there are also anatomical variants in specimens Cr 4 - 6, Cr 8 - 6, Cr 11 - 1, Cr 30 - 13, and Cr 70 - 2 with smaller epidermal cells and very thin cell walls, larger paracytic stomata, and thickened guard cells without trichomes. These data allow the identification two fossil taxa of this genus that probably correspond to independent species. However, this point is beyond the scope of the present work and should be reevaluated in future studies.	en	León, María Patricia Velasco de, Martínez, Erika Lourdes Ortiz, Barragan, Miguel Angel Flores, Madrid, Diana Silvia Guzmán, Martinez, Pedro Christian Martínez (2024): New records of Bennettitales and associated flora from the Jurassic of the Cualac Formation, Mexico.
