Morphometric study of porosity and morphology of fossil Globigerinoides, during the Late Oligocene and Early Pliocene. Implications for the construction of a climatic and environmental paleoproxy

Globigerinoides is a group of planktonic foraminifera who appeared in the world's oceans around the Late Oligocene and are still largely present in the equatorial, tropical and subtropical regions of the modern Ocean. Several proposals of phylogeny have been presented since their discovery by d'Orbigny (1839), without reaching a consensus. Recent molecular studies have revealed an unexpectedly great and sometimes cryptic complexity, which further complicates the relationships between species of this genus. […]
