The eggshell of the Eocene bird Lithornis

, 2005
Although the fossil bird Lithornis has been known for more than a century, only in the 1980s were its affinities within the palaeognathous birds (Aves, Palaeognathae) realized and demonstrated by use of osteological characters.

Comparison of micrometer- and scanning electron microscope-based measurements of avian eggshell thickness

, 2010
The study of avian eggshell structure, including composition, pigmentation, thickness, and strength, has important ecological and economic implications. Previous investigators have used a variety of techniques to derive either direct measures or indirect

A Phylogenetic Assembly and Positive Selection Analysis of the DMP1 Gene in Aves, Testudines and Crocodilia

, 2020
The DMP1 gene codes for proteins that play a role in the calcification of hard tissues, including dentin, in vertebrates. Deleterious mutations in the gene can cause genetic disorders such as rickets in humans.
