Coniacian, Late Cretaceous.

E m e n d e d d i a g n o s i s. Ovuliferous cone scale complex cuneate, length greater than width, laterally narrow-winged, having one seed per cone scale complex. Ligula 2/3 to 1/1 of the length of the seed. Seed oval, oblong-oval to oblong-ovate. In cross-section wide oval to rhomboid, considerably narrower and shorter than the cone scale (emended from Kunzmann 2007b).

O t h e r m a t e r i a l. NM-F 5010, coll. National Museum, Prague, leg. Z. Dvořák 1997 ( Text-fig. 1b ); No. 451, coll. Knoll.

O t h e r o c c u r r e n c e s. Radovesice near Kučlín, the Czech Republic (Teplice Formation, early Coniacian, Late Cretaceous); Hauset near Aachen, Belgium (late Santonian, Late Cretaceous; Kunzmann 2007b).

D e s c r i p t i o n. The holotype ( Text-fig. 1a ) is a laterally narrow cuneate ovuliferous cone scale complex 15 mm wide × 29 mm long. It shows a centrally placed oval oblong seed 16 mm × 6 mm. A fragment of ligula is 8 mm wide. The apical part of the cone scale complex exhibits a terminal projection 6 mm wide × 7.5 mm long. The cone scale complex is partly limonitised, showing resin fragments imitating resin canals in the apical and central parts, some of irregular shape, always less the 0.2 mm in diameter .

The newly found specimen, No. NM-F 5010, ( Text-fig. 1b ) is an impression in sandy marlstone from the Teplice Formation. It shows a deltoid cone scale complex, 20 mm wide × 27 mm long. The terminal projection is 7 mm wide × 5 mm long. The centrally placed seed impression is an elongate ovoid 15 mm × 5 mm. The ligula impression is 9 mm wide.
