This tool implements a Maximum Likelihood (ML) fossil placement algorithm developed by Berger and Stamatakis {Berger, 2009}. This method assumes a molecular phylogeny for a set of extant taxa, and then generates weights for each morphological character based on congruence with the molecular phylogeny. Next, the method attaches the fossils to every possible branch of the molecular tree, and in each case calculates the likelihood of observing the weighted morphological data. The placement of each fossil in the molecular tree is the placement with the maximum likelihood estimate.
