). Additional grains were also found in a pollen clump, possibly a coprolite, together with several other kinds of pollen. Pollen grains found in situ are small, about 17–20 µm long, elliptical to almost circular in equatorial outline and monocolpate. The colpus is short. The exine is semitectate-reticulate and columellate (
