IAA
Reason: This file contains unpublished age and locality data by our collaborators. The age of each samples is determined by biostratigraphy of calcareous nannofossils and planktic foraminifera. So the age information will be published later, before that, the file should be under embargo.

Supporting data for "Cenozoic dynamics of shallow marine biodiversity"
This is the fossil ostracod census dataset used in my research entitled "Cenozoic dynamics of shallow marine biodiversity". It shows the biodiversity and species compositional changes across the Paleocene-Eocene Thermal Maximum (PETM), and the Neogene period. I have two sediment cores (SDB and MCBR) of the PETM interval from the North Atlantic coastal plain in shallow-marine, subtropical to temperate paleoenvironmental conditions. The SDB and MCBR core were sub-sampled at approximately 12 cm and 10 cm intervals, respectively, and I counted the number of ostracod specimens of different species from each sub-sample to construct the datasets.
The file titled "IAA" contains the fossil ostracod census data of 180 outcrop sediment samples from the Indo-Australian Archipelago (IAA). Microfossil ostracod specimens from each sample were counted and recorded. Ages of these samples range from early Miocene to Pleistocene. As the dataset shows the abundance and species richness of ostracods across the Neogene, it has been used to reveal the historical development of tropical marine biodiversity hotspot in the IAA.
