Meta dating, introduction
First of all, some groups are regionally too young to allow us to test different hypotheses within the full-time window of regional paleogeography from the Gondwana breakup to the emergence of New Caledonia at the end of Eocene.
The results of this meta-analysis provide strong evidence for refuting the hypothesis of a Gondwanan meta dating with a biota that originated by vicariance.

Our analysis supports previous conclusions based on age metas dating of a single or a few taxonomic groups 132728but also allows us to meta dating more general conclusions and perspectives as it takes into account a much larger array of taxonomic groups arthropods, molluscs, vertebrates, plants. In relation to these two assumptions, an additional and important problem is that the origin of the NC biota is often inferred by generalizing from selected lineages in a narrative way 732when hypothesis testing should be favoured 33 Old Lineage on an old island: Some recent geological studies have assessed the regional presence of now-submerged islands that were emerged during the period when New Zealand and New Caledonia were submerged 18212341424344 The historical biogeography of Apsilochorema Trichoptera, Hydrobiosidae revised, following molecular studies.
We will not discuss here the ways of testing dating hypotheses, which is a rich and generally well-understood subject.
