NT mtDNA tree (K-Pg constraint)
, 2015 Timetree from divergence dating analysis in BEAST using NT coded mtDNA dataset, with topology constrained and additional maximum constraints applied so that all divergences except those for the Palaeognathae, Neognathae, and Galloanserae are constrained ...

Non-neotenous origin of the palaeognathous (Aves) pterygoid-palate complex
, 2002 Recent studies on the phylogeny of modern birds have indicated that the Palaeognathae may not be the most basal group in modern birds, but are derived within the group.

Introduction to the Palaeognathae: Mostly Flightless
This site introduces the Palaeognathae, birds grouped together on the basis of their jaw structure. The site explains the basis for the classification and gives examples of birds that fit into this classification. Most birds in this group, which includes

Anatomy, taxonomy, and relationships of lithornithids.
, 2016 91 pages : illustrations (some color), map ; 26 cm.Fossil remains of Paleogene Palaeognathae are poorly documented and are exceedingly rare. One group of palaeognaths, the lithornithids, is well represented in the Paleogene of North America. Nevertheless,

The phylogenetic distribution of ultraviolet sensitivity in birds
, 2013 Background: Colour vision in birds can be categorized into two classes, the ultraviolet (UVS) and violet sensitive (VS). Their phylogenetic distributions have traditionally been regarded as highly conserved.
