Nannoceratopsis evae
Nannoceratopsis evae Prauss, 1989
Holotype: Prauss, 1989, pl.8, figs.19-21, text-fig.3
Locus typicus: SPD 10 Bore, Germany
Stratum typicum: Early Aalenian
Translation Prauss, 1989: LPP
Original description: Prauss, 1989, p.13
An especially small Nannoceratopsis species with subtrapezoidal outline in lateral view, solid pedium and strong, coarsely reticulate luxuria. Ventral antapical horn strongly reduced, often not present. Short dorsal antapical horn, often merely indicated. Overall, the form is clearly smaller than all presently known species of this genus.
Dimensions: l: 61,5(66,0)75,0 Ám, w: 46,1(48,7)50,0 Ám; l:w (average) 1,3.
Affinities: Prauss, 1989, p.13
Apart from its small size, N, evae is characterized by the relatively high, coarse surface structure. Often the network structures spread from the hypocyst over the cingular area towards the apex. The absence of the ventral antapical horn and the small dorsal antapical horn are also typical.
Poulsen 1996 p.55
Remarks. Nannoceratopsis sp. 1 of Dybkjaer (1991, p. 30, pl. 15, fig. 10) is here regarded as N. evae.
Recorded occurrence. Denmark: L. spinosa Zone, Subzone b? (Dybkjaer, l991).
