A paper in Nature this week reports that ray-finned fishes may be a whole 40 million years younger than previously thought—and that a number of fossil species have been placed in the wrong slot on the family tree. The finding points to how crucial this period in evolutionary history is to our understanding of the evolution of modern vertebrates. And in the process, it clarifies the history of a strange fish that still lives in Africa called the bichir.

So we have a 10% dating error in about 350millon years.

I'd have liked to have seen a picture of the new and the old family trees though.
