I think Ken´s point is that nodes on dated phylogenies come with an uncertainty range, and hopefully the authors of the dated phylogeny provided them. Saying 35my and 35my (-20my) are very different things, so it is hardly proof of a fatal flaw in the edifice on fossil calibrated molecular phylogenies. In any case, the more fossils the better the calibration. In regards to crown versus stem, I would point out that if the fossil looks like a rabbit but you are uncertain about its exact placement, you assign it to all the rabbits (basal). It is not necessarily the best solution but it is the most parsimonius.
