) and from the ‘Chaumont-en-Vexin sands’ at Chaumont-en-Vexin in the Paris Basin, both attributable to the base of NP14. It is also known from the base of the ‘Glauconie Grossière s.s.’ at Prémontré and at the top of the ‘Glauconie Grossière s.s.’ at Gisors (Steurbaut unpublished). Thus, its range appears to be restricted to NP14, if the spotty occurrences in lower NP15 (base Lede Sand Formation and base Wemmel Sand Member) are considered to be due to reworking.
