| Summary: | This archive contains raw data and intermediate results to morphometric investigations about the evolution of menardiform globorotalids (planktonic foraminifera) from the Cipero Formation, Cipero Coast and surrounding areas, SW Trinidad, Caribbean Sea. The goal of this study was to evaluate the feasibility for morphometric investigations about planktonic foraminiferal evolution from historical samples, that once were collected from iconic Oligocene-Miocene foraminiferal zonal type and co-type localities during the 1950ies in southwestern Trinidad and now are curated along the micropaleontological collections of the Natural History Museum in Basel (NMB), Switzerland. The present study extends previous similar investigations by the second author about shell evolution of Late Miocene through Quaternary Globorotalia menardii to early Miocene forms from the tropical West Atlantic by including ancestral forms like G. archeomenardii and G. praemenardii from Trinidad areas, from where these forms once have been ... |
