Species Globorotalia limbata Fornasini 1902


Alternative name:
Globorotalia (Menardella) limbata Fornasini 1902
Discussion / Comments:
Chaisson & Leckie (1993):
Remarks: This "species" is essentially a Globorotalia menardii with seven to eight chambers in the final whorl, rather than five to six and a half. Similar species: Six to six and a half chambered specimens of "menardiiform" taxa are problematic, and using the shape of the spiral sutures as a secondary distinguishing characteristic is difficult as all degrees of "limbation" may be observed. Such forms are assigned, therefore, to G. menardii s.l. G. limbata is gradational with G. multicamerata. Seven- to eight-chambered forms were assigned to G. limbata, whereas nine-chambered forms were assigned to G. multicamerata. G. limbata is more oblate than G. pseudomiocenica and is less vaulted on the umbilical side. Kennett and Srinivasan (1983) consider G. pseudomiocenica to be a junior synonym of G. limbata. G. limbata has a thicker test than G. pertenuis.
