List of cladograms tested for their correspondence with stratigraphic data. In this case, all cladograms come from one source, the review volume by Kenrick and Crane (1997). 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
