Calcareous nannofossil range charts for ODP Holes 998A and 999A, with age models, and relative abundance

Compiled qualitative and quantitative counts of calcareous nannofossils of ODP Holes 998A and 999A. Data represents the identified taxonomic assemblage (Genus, species), overall species richness, sample id code, sample depth, and calculated age per sample. In addition the Hole 999A range chart has relative abundance data of C. floridanus and calculated age models for published figures. Ages are calculated based on known or identified biostratigraphic events whereby the age between events is divided by the depth deposited between events.
