Amniote-reptile-bird trees

List of cladograms tested for their correspondence with stratigraphic data. Cladograms are listed alphabetically. For each group, data are listed in order, as follows:

  • Group name
  • Tree size (number of terminals)
  • SRL, Standard range length, the total time represented by known fossil ranges
  • MIG, Minimum implied gap or ‘ghost range’
  • Gmin, the minimum possible ghost range when cladogram branches are rearranged
  • Gmax, the maximum possible ghost range when cladogram branches are rearranged
  • RCI, the Relative completeness index (Benton, 1994)
  • RCI and GER Sig., significance of the RCI and GER measures
  • No. consistent nodes, the number of stratigraphically consistent nodes
  • SCI, the Stratigraphic consistency index (Huelsenbeck, 1994)
  • SCI Sig., significance of the SCI measure
  • GER, the Gap excess ratio (Wills, 1999)
  • Range, the broad stratigraphic range of the cladogram
  • Reference, the source of the cladogram assessed
