Global compilation of the first occurrence of Gephyrocapsa huxleyi and other Gephyrocapsa species from sediment core samples

The data compilation includes the first occurrence of G. huxleyi and other species of Gephyrocapsa as revealed by Quaternary sediment samples from the world oceans. This new synthesis includes previously published data, all with rigorous relationships of their emergence events with marine isotope stages based on good quality oxygen isotope stratigraphy and/or astronomical tuning from each sediment core.
