1. All tested members of Heterodontosauridae form a polytomy . 2. However, other parts of the tree lost much resolution creating a large polytomy of large groups above Erythrosuchidae. 3. Instead, erpetosuchids formed a polytomy or unresolved evolutionary relationship at the base of Archosauria along with several other groups. 4. "Neuquenraptor " was assigned by Novas and Pol to the Dromaeosauridae in a polytomy with several dromaeosaurid taxa. 5. These species form a polytomy including " Glossodoris baumanni " and three clades of Atlantic and Eastern Pacific chromodorids. 6. A phylogenetic analysis places both species in a polytomy with " Gualosuchus " as the most advanced members of Proterochampsia. 7. Such studies have so far revealed almost nothing about relationships within the genus, placing nearly all of the sampled species in a large polytomy . 8. In a * strict consensus, * only nodes found in every tree are shown, and the rest are collapsed into an unresolved polytomy . 9. Different lineages exist that are apparently not stable in space and time, are best described as polytomy , from which the similar island taxa derive. 10. After " Aetosaurus ", there is a polytomy of three smaller clades in which it is unknown which clade diverged first from the group.
