and Remiornis. While competition and lack thereof between ratites and eogruiids has been examined extensively, niche partitioning between geranoidids and ratites has currently not, in spite of factors like geranoidids being most common in North America, where there are no ratites, or the fact that some European ratites were carnivorous.

Paleoecology and distribution

Geranoidids are most common in Eocene fossil sites in North America, particularly in the Willwood Formation
