    How big is Globorotalia multicamerata?
    Globorotalia multicamerata attains the largest size of the three species at times before 3 Ma (Fig. 5c). It surpasses G. menardii and G. limbata in test-size mean and maximum values in all samples in which it occurs (Fig. 5d). Exceptions are the samples at 6.07 Ma, which have the same mean value as G. limbata, and at 2.057 Ma.

    Are Globorotalia multicamerata morphologically similar?
    However, morphological overlap between these species point to strong interspecific size variation. Globorotalia multicamerata exhibited the largest mean population test size and G. menardii the smallest mean size, while G. limbata was intermediate.

    When did Globorotalia ( menardella) multicamerata evolve?
    The species gave rise to Globorotalia ( Menardella) limbata and Globorotalia ( Menardella) multicamerata during the middle Miocene zone N14 and the Late Miocene zone N17b ( Kennett and Srinivasan, 1983 ). A progressive evolution to larger size occurred between 3.11 and 2.29 Ma ( Knappertsbusch, 2007 ).

    Is there a morphological intergradation between Globorotalia limbata and multicamerata?
    A continuous morphological intergradation exists between typical Gr. (M.) limbata and Gr. (M.) multicamerata, and the distinction between these species is somewhat difficult to recognize, especially in Late Miocene Zone N17B. [Kennett & Srinivasan 1983] Most likely ancestor:Globorotalia limbata - at confidence level 4 (out of 5).

    Test-size evolution of the planktonic foraminifer Globorotalia menardii in the eastern tropical Atlantic since the Late Miocene
    The mean test size of planktonic foraminifera (PF) is known to have increased especially during the last 12 Myr, probably in terms of an adaptive response to an intensification of the surface-water stratification. On geologically short timescales, the
