# Calculate stratigraphic fit measures treating ages as ranges: <- StratPhyloCongruence(trees = Dipnoi$tree,
  ages = Dipnoi$ages, rlen = 0, method = "basic", samp.perm=5,
  rand.perm = 5, hard = TRUE, randomly.sample.ages = FALSE,
  fix.topology = FALSE, fix.outgroup = TRUE,
  outgroup.taxon = "Psarolepis_romeri")

# Show just the output for the input tree(s)$input.tree.results
