Figure 9 in New fossil mousebird (Aves: Coliiformes) with feather preservation provides insight into the ecological diversity of an Eocene North American avifauna

Figure 9. Phylogeny of the Coliiformes calibrated to the stratigraphic record. Character states reconstructed as unambiguous synapomorphies in the strict consensus tree from Figure 8B are listed for each branch. Additional character states that are reconstructed as unambiguous synapomorphies in all most parsimonious trees combined in this consensus (but not reconstructed as such in the strict consensus tree because of soft polytomies) are listed in italics. Characters that exhibit homoplasy within Coliiformes are indicated with an asterisk. As a result of the lack of phylogenetically constrained Neogene mousebird fossils, the timing of divergences within Coliidae is uncertain, but we have placed the Urocolius/Colius divergence in the Pliocene, reflecting probable African representatives of at least the extant Colius lineage (Haarhoff, 1993). Stratigraphic ranges of European taxa are in light grey; North American taxa in are in dark grey. All extant Coliiformes are restricted to Africa. Life reconstructions by Kristin Lamm.
