Taxon description

Pazos et al., 2015a

Diagnosis: Dictyodora with differentiable lower (basal section) and a vertical section that ends in an upper level (stratinomic level). The lower section is composed of a basal horizontal meandering part, wider than the vertical wall that is differentiable in three morphological types of meanders. The lower meanders are very similar in shape but thinner than the basal section, with always divergent limbs and rounded turns. The meanders of the upper level are subtriangular, with almost orthogonal angles between limbs and pointed turns. The vertical connection between the two meander types consists of asymmetrical, tilted and curved meanders of variable shape pointed in one direction. In full relief, the shape is helical to irregular, but never coiling; vertical striations in the wall may be observable in lateral views.
