The extinct Lithornithidae include several genera and species of flying palaeognathous birds of controversial affinities known from the Early Paleogene of North America and Europe. An almost complete, articulated skeleton from the Early Eocene marine deposits of the Fur Formation (Denmark) was recently assigned to Lithornis vulturinus Owen, 1840.

The FASEB Journal, 2022
In modern birds (Palaeognathae and Neognathae), the adult skull combines tightly sutured and co‐ossified units with kinetic flexion zones, serving as a multitasking ‘second hand’. How the skull osteology changes postnatally in different bird lineages is underexplored, especially regarding the morphological and physiological changes across the altricial‐

Phylogenetic interpretation of eggs and eggshells: implications for phylogeny of Palaeognathae
Alcheringa: An Australasian Journal of Palaeontology, 2006This oological analysis supports Palaeognathae monophyly, and places Dromornithidae within Neognathae, the sister clade of Paleognathae. This Dromornithidae relationship is congruent with a recent phylogenetic hypothesis, based on cranial characters, that differs from the original assignment of this group of extinct birds to the Palaeognathae.

We examined the external anatomy of the endocast of the Greater Rhea (Rhea americana, Palaeognathae), during 3 main stages of its postnatal life, and compared it with information available on other palaeognathous birds. Series of scans with spiral computed tomographies were obtained from 3 skulls of different ages (chick, juvenile and adult) of R ...
