INV 2014.106. 12.4 14.7 6.7 5.2 Remarks – G. curviceps is perhaps the most frequently cited Pliensbachian rhynchonellid species in Europe. It was profusely illustrated by ALMÉRAS et al. (2010, l.c.), ALMÉRAS & COUGNON (2013, l.c.) and HÖFLINGER (2012, l.c.) what served a firm basis for the identification of our specimens. G. curviceps was record- ed in a great number of localities in the Mediterranean region as well and when I was able to check personally in the respective collections, I recognized that G. curviceps became a comfortably used collective taxon among the numerous and partly vaguely defined species of the genus Gibbirhynchia . The date of publication of this species is inconsistently cited by different authors as 1856 or 1858. Quenstedt’s “Der Jura ” was published in several parts in different years; the species curviceps was described in the first part (p. 138) therefore the proper date is 1856. G. curviceps is a Pliensbachian species with cosmopolitan geographical distribution.
