Diagnosis
ReferenceDiagnosis
K. E. Mikhailov 1991Angustispherulithic morphotype; pore system of mixed type, mainly rimocanaliculate + angusticanaliculate; sculptured surface: sagenotuberculate ornamentation (often variant 3), or smooth surface; ellipsoid - subspherical eggs; "thick" (>2 mm) and "medium" (>1 mm) eggshell.
K. E. Mikhailov 1997Angustispherulitic morphotype, complex rimo-prolato-angusticanaliculate pore system; smooth or sagenotuberculated eggshell surface.
