CHARADRIIFORMES a complete phylogeny for all birds, from W. Jetz et al. 2012. The order: CHARADRIIFORMES
Evolutionary History
• An ancient group, possibly 80+ MYA
• Cretaceous/Paleogene bits and fossil records of Neognathae similarities but may be convergent evolution
• Undisputed remains from mid- Paleogene (~45 MYA)
• Present Day families emerged by Eocene/Oligocene ~35-30 MYA Shorebirds: The order CHARADRIIFORMES Families, taxonomic order -
