| Summary: | <p>This dataset is a comprehensive, global compilation of
published uranium–thorium (U-series) dated fossil coral records from
<span class="inline-formula">∼</span> 150 000–110 000 years ago, as well as associated
elevation measurements and sample metadata. In total, 1312 U-series
measurements from 994 unique coral colonies are included in the current
version of the dataset, all of which have been normalized and recalculated
using the same decay constant values. Of these measurements, 444 analyses
from 330 colonies are relative sea-level indicators, whereas 15 analyses
from 13 colonies are marine limiting. Two example geochemical screening
criteria have been included to assist users with identifying altered fossil
corals that display geochemical open-system behavior, and the originally
published interpretations on age quality have been preserved within the
sample metadata. Additionally, a clear distinction has been made between
coral colonies that are in primary growth position, which may be used for
relative sea-level reconstructions, and colonies that have been
transported/reworked, which cannot be used for these purposes. Future
research efforts involving fossil coral sea-level reconstructions should
emphasize an “integrated” and holistic approach that combines careful
assessment of U-series age quality with high-precision surveying techniques
and detailed facies/stratigraphic observations. This database is available
