e0“climatic fluctuations in the Antarctic continent during the middle to late-Miocene led to the isolation of Phaeomegaceros taxa with both processes (dispersal events and vicariance) acting on the independent evolution of the disjunct clades”

Other claims from this paper (5)
- Observation Phylogenetic analyses supported Phaeomegaceros monophyly.
- Observation Phaeomegaceros comprises New Zealand and Austral American clades differing in a spore-face depression.
- Observation Biogeographical analyses inferred a New Zealand and Antarctic ancestral area in the Late Cretaceous.
- Observation Austral American Phaeomegaceros species diverged during the Eocene.
- Mechanism The authors attribute recent Austral American diversification and range expansion to dispersal and cladogenesis associated with geological changes.
