Hi, molecular clock rates are widely used to link genetic divergence in invertebrates to vicariance; for example, geological events in the Pleistocene, or earlier in the Miocene. My question is how far back in time is appropriate for (invertebrate) mtCOI dating analysis? Is the Mesozoic too far back in time? (btw, I realise the use of mtCOI molecular clock rates are controversial)
Riddle and Hafner (chapter 7 in Biogeography in a changing world, Ed. Ebach and Tangney 2007) compiled a graph showing keyword search on ISI web of science using "phylogeograph" and geological time, and had produced some results for "Cretaceous". However, there are considerably more results for Holocene-Miocene than Oligocene to Cretaceous. Pleistocene has the modal peak.
Although this does not answer why there are not many phylogeographic studies for Oligocene-Cretaceous events, which is a question I am also wondering, I hope this is helpful to you.
