Morphological study of the upper, lower and third eyelids in the African black ostrich (Struthio camelus camelusL., 1758) (Aves: Struthioniformes) during the embryonic and postnatal period [PDF]
Italian Journal of Zoology, 2016 AbstractThe upper, lower and third eyelids are accessory organs of the eye. The aim of this study was to describe the development of the upper, lower and third eyelids in ostriches in the embryonic and postnatal period and to characterise the conjunctiva-associated lymphoid tissue (CALT) in the eyelids.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

A novel family of repetitive DNA sequences amplified site-specifically on the W chromosomes in Neognathous birds. [PDF]
, 2006 A novel family of repetitive DNA sequences was molecularly cloned from ApaI-digested genomic DNA of two Galliformes species, Japanese quail (Coturnix japonica) and guinea fowl (Numida meleagris), and characterized by chromosome in-situ hybridization and ...

Journal of Morphology, Volume 285, Issue 6, June 2024.We describe the nearly complete digital endocasts of the brain and bony labyrinth of the neotype specimen of Lithornis vulturinus, a palaeognathous bird from the early Eocene of Europe. Lithornis may provide the clearest insights to date into the neuroanatomy of the ancestral crown bird, combining an ancestrally unflexed brain with a caudally oriented ...

Global diversity and adaptations of avian eggshell thickness indices
Ibis, Volume 166, Issue 2, Page 534-550, April 2024.The amniote eggshell is a fundamental aspect of the embryo life‐support system, protecting it from UV light, microbes and mechanical damage, while regulating gas exchange and providing calcium for growth. The thickness of eggshells is highly diverse across modern birds and influences multiple eggshell functions, yet the selective pressures driving ...
