Entity GG1 (entity_id = 357) and GG2 (entity_id = 358) do not have age models in original publication.// GG1 (entity_id = 357): the basal TIMS date (9104 ka) has a large error because of detrital thorium and so is statistically indistinguishable from the next youngest date (9163 ka), which has a small 2-sigma error. In order to avoid an apparent age reversal, the basal date was therefore assigned a value of 9721 ka.
