The evolution of tinamous (Palaeognathae: Tinamidae) in light of molecular and combined analyses
Zoological Journal of the Linnean Society, 2021Abstract The Neotropical tinamous are of particular interest in our efforts to understand the evolution of modern birds. They inhabit both forested and open environments and, although volant, have limited flight capabilities. Numerous studies have recognized the monophyly of tinamous and their relationships either as sister to the ...

Phylogenetic interpretation of eggs and eggshells: implications for phylogeny of Palaeognathae
Alcheringa, 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.

Hindlimb bones texture through postnatal ages of Rhea americana (Aves: Palaeognathae)
Anatomia, Histologia, Embryologia, 2023AbstractThe bone texture of Rhea americana was evaluated through the examination of a postnatal ontogenetic series. The hind limb bone surfaces of specimens of one, three and five months old, and adults were compared to characterize each stage according to the morphological features generated by their differential ossification.

The feeding apparatus of Rhea americana (Aves, Palaeognathae): Jaw myology and ontogenetic allometry
Journal of Morphology, 2023AbstractIn birds, the jaw musculature is a crucial adaptive feature involved in feeding. The morphological traits and postnatal growth patterns of jaw muscles constitute a useful proxy to interpret feeding function and ecology. This study aims to describe the jaw muscles of Rhea americana and explore their postnatal growth pattern.
