Wright & Stigall (2013a) divided cladogenetic events in these taxa into two temporal bins.
To obtain relative estimates of cladogenetic timing, we performed an uncorrelated lognormal relaxed-clock Bayesian analysis of the ND2 dataset in BEAST (Drummond and Rambaut 2007).
With demonstrations that fern speciation takes advantage of new habitats opened when angiosperms diversify, it may be possible to study early stages in the cladogenetic process of ferns.
