Genus Ephedripites Bolkhovitina, 1953

Fig. 19M .

Remarks.—Representatives of Ephedripites Bolkhovitina, 1953 are present in Palynoassemblages A and B; they were produced by species of Ephedraceae Dumortier, 1829 (Ruiz and Quattrochio 1997).

Class unknown

Genus Cycadopites Wodehouse, 1933

Type: Cycadopites follicularis Wilson and Webster 1946 ; Maastrichtian to Paleogene, Montana, USA .

Remarks.— Cycadopites was proposed by Wodehouse (1933) without selecting the type species, the material from the Eocene Green River Fm. at Parachute Creek, Colorado, being described as Cycadopites sp. The type species from the Fort Union Fm. of Montana was selected by Wilson and Webster (1946). However, similarly as in the case of Podocarpidites described above, the authorship of the genus should be described to Wodehouse (1933), following Andrews (1955: 141) not to “Wodehouse ex Wilson and Webster”, as done, among others, by Potonié (1958: 92) or Leffingwell (1970: 28).

Cycadopites sp.

Fig. 18K.

Remarks.— Cycadopites Wodehouse, 1933 , is a pollen type that can be derived from Bennettitales, Ginkgoales, Cycadales , Pentoxylales, and some Peltaspermales (Zavialova and van Konijnenburg-van Cittert 2012: 15 and references therein). Found in almost all samples from the section RK-4.
