Morphospecies of planktonic foraminifera are clusters of eco-genotypes that show small but significant shell morphological differences (pseudo-cryptic species).This discovery opens a new perspective for improving the accuracy and resolving power of paleoceanographic reconstructions. Unfortunately, c...
