2000a Oncopareia bredai Bosquet ; Tshudy and Sorhannus, figs. 4.5–4.8.

Material examined. Three specimens, IRScNB 90-19f, 90-19h and 90- 19m (one complete and two incomplete palms).

Description. Palm bulbous, about 1.7x longer than wide; widest and thickest near distal end. Upper and lower surfaces convex. Outer margin rounded; inner margin with very prominent, broad, flattopped keel. Keel higher, narrower, proximally; lower, broader distally. Palm upper surface with very fine (IRScNB 90-19f) or fine (IRScNB 90- 19m) granules, with spine near outer-proximal corner. Lower surface and outer margin smooth. Inner marginal keel bearing a few stout, alternating spines on keel edges; otherwise with minute, densely distributed granules.

Remarks. These specimens are distinguished from O. bredai on the basis of the prominent keel on the inner margin of the claw.

Range and occurrence. Upper Maastrichtian (Kunrade Formation) of Kunrade, southern Limburg, the Netherlands.
