FIGURE 6 in Archaeochionelasmus nekvasilovae gen. et sp. nov. (Cirripedia, Balanomorpha, Chionelasmatoidea) from the Bohemian Cretaceous Basin (Czech Republic): the first bona fide Cretaceous neobalanoform

FIGURE 6. Reconstruction of †Archaeochionelasmus nekvasilovae Kočí, Newman & Buckeridge, gen. et sp. nov. A. Wall based on the fossil, operculum low in accordance with the low profile and tight sutures of the wall that suggest it may have been an epibiont of large marine reptiles or cephalopods. The presence of imbricating plates is based on ribbons of sediment adhering to the base of the wall plates. Their arrangement is patterned after that found in B, the generalized form as typified by Eochionelasmus ohtai Yamaguchi & Newman, 1990. which is the basis for their arrangement in higher forms; cf. Waikalasma boucheti Buckeridge, 1996 and Catophragmus in Ross & Newman (2001). Parietal plates R, RL, CL and C (rostrum, rostrolatus, carinolatus & carina respectively) and opercular s and t (scutum and tergum respectively), with the relative positions of the paired and unpaired plates making up the imbricating whorls identified accordingly.

FIGURE 3. Comparison of (A) the reconstructed wall of Archaeochionelasmus nekvasilovae gen. et sp. nov. with (B) an illustration of a juvenile of Chionelasmus ohtai having the first whorl of basal imbricating plates (from a line drawing by D.S. Jones, with permission in litt. 2016), and (C) an adult of Chionelasmus ohtai; CL overlaps the ala of C, as is indicated on left side, whereas CL abuts rather than overlaps R (Yamaguchi & Newman 1990, fig. 8B), their articulation being strengthened and protected by the addition of the RL applied over the abutment of CL and R, dividing SRL into more or less equal halves.
