Where: Miyazaki, Japan (31.5° N, 131.2° E: paleocoordinates 36.5° N, 128.1° E)

• coordinate stated in text

When: Nichinan Group, Early/Lower Oligocene to Early/Lower Oligocene (33.9 - 16.0 Ma)

• The fossilifer- ous horizon belongs to the coherent unit of the Nichinan Group and appears to be located within the Honjo Olis- tolith of Sakai et al. (1987). Earlier work referred the deposits in the Takamatsu area to the Kushima Formation and dated them to the middle Eocene–early Oligocene (Kato, 1985). However, this subdivision of the sequence appears to include portions of the chaotic unit of the Nichinan Group, which is in turn derived from the older Hyuga Group (Sakai et al., 1987), and thus likely to pro- vide unreliable dates.
