“…Cerodinium diebelii has its LO in Samples RM-441 and RL-520. The lowest occurrence of C. diebelii has been reported in the upper Campanian by Lentin (1980), Williams and Bujak (1985) and Boltenhagen (1977) (as Ceratiopsis leptoderma). May (1980) regarded the lowest occurrence of C. diebelii to be in the lower Maastrichtian in New Jersey, very close to the Campanian/ Maastrichtian boundary.…”

“…However, the two paratypes illustrated by Srivastava (1995) have convex sides and they do show a periarcheopyle extending to the apical horn (which is supposed to be a common feature of Cerodinium species). Some of the specimens of C. pannuceum recovered from the Río Molino and Río Loro section look like the specimens of Cerodinium obliquipes from Gabon illustrated by Boltenhagen (1977) as Deflandrea obliquipes (pl. 15, figs.…”

Two outcrop sections from the Maastrichtian Colón and Mito Juan Formations were analyzed for dinoflagellate cyst biostratigraphy. Samples from the Río Molino section (Cesar-Ranchería Basin, Colombia) represent a subset of samples from the 240 mthick hemipelagic limestones and calcareous mudstones reported in Martínez's (1989) foraminiferal study. The upper Campanian, lower Maastrichtian and uppermost Maastrichtian intervals were identified in this section based on some significant dinocyst biostratigraphic events, which are in agreement with planktonic foraminiferal data. In ascending stratigraphic order these events include the lowest occurrence (LO) of Areoligera spp., LO of Senegalinium spp., highest occurrence (HO) of Trichodinium castanea, HO of Xenascus ceratioides, LO of Cerodinium diebelii, LO of Trithyrodinium evittii, HO of Odontochitina operculata, LO of Phelodinium tricuspe, HO of Palaeohystrichophora infusorioides, LO of Glaphyrocysta perforata, LO of Disphaerogena carposphaeropsis and LO of Manumiella seelandica.
