In particular, we perform a multidisciplinary approach studying: 1) the morphology of the new extinct greenfinch, comparing it with the extant finches; 2) the extinction date of the new species using an AMS 14C dating from the collagen of its bones; and 3) the colonization times of extant chaffinch species inferred from sequences of the mitochondrial cytochrome b gene.

Previous estimates had suggested Araguainha was 10m years younger, but Dr Tohver has put it within geological spitting distance of the extinction date, which itself has a margin of error of plus or minus 200,000 years.Which would all be fine and dandy, except most people think Araguainha is too small to be the culprit.
