FIGURE 11. Craniella crustocorticata van Soest 2017: A, specimen from SE Brazil, with a root (MNRJ 6059); B, longitudinal cut showing internally a radial organization (MNRJ 6059); C, external surface of one of the specimens from NE Brazil (root lost during collection), (UFPEPOR 1785); D, a radial organization of another specimen from NE Brazil (root lost during collection), (UFPEPOR 2152); E, conules on the surface (MNRJ 6059); F, detail of the basal region (MNRJ 6059); G, transverse section showing a radial skeleton with choanosomal bundles of oxeas ending in a conule at the surface (MNRJ 6059); H, tangential section of the surface showing cortical oxeas III (MNRJ 6059); I, transverse section showing ectosomal region with oxeas III disposed perpendicular (small forms; black arrows) and tangential to the surface (larger forms; white arrows); J, arrows pointing to cladomes of anatriaenes present in the root. Scale bars: A–B = 10 mm; C–D = 2 mm; E–F = 1 mm; G–I = 500 µm; J = 100µm.
