Relationship between mediotest and callotest patterns in the studied terebratulidines; schemes based on particular transversal sections (not to scale). The drawings show white infillings representing crural base, gradient grey infillings representing outer hinge plate (mediotest) and dark grey infillings representing appositional layers (callotest). a Carneithyris subregularis (Quenstedt 1871) (section 6.0 mm). b Carneithyris aequivalvis (Schafhäutl 1863) (section 4.0 mm). c Carneithyris hilarionis (Davidson 1870) (section 2.9 mm). d Gryphus vitreus (Born 1778), section 3.25 mm of a specimen (length 25.5 mm, width 22.4 mm, thickness 13.7 mm), Holocene, Adriatic Sea. Carneithyris carnea (Sowerby 1812), section 6.6 mm (e) and 7.6 mm (f) of a specimen (length 27.4 mm, width 23.2 mm, thickness 16.4 mm) from the Late Campanian, Harmignies near Mons (Belgium).
