Table 2: Comparison of features and biometry of modern and fossil L. crispatum. The specimens of L. crispatum
from the Lower Serravallian of Slovakia, Sandberg locality, were poorly preserved. Since it was not possible to make
an appropriate number of measurements for most of the parameters, they are omitted from the table; VC= ventral
core; PF=peripheral zone; s.d. =standard deviation; //= insufficient data cover.
