Morphology forms the most fundamental level of data in vertebrate palaeontology because it
is through interpretations of morphology that taxa are identified, creating the basis for broad …

Background The origin of birds is one of the most enduring and dramatic evolutionary
debates. The hypothesis that the primarily small-sized birds are nested within a theropod …

Calcified eggshells protect developing embryos against environmental stress and contribute
to reproductive success. As modern crocodilians and birds lay hard-shelled eggs, this …

Sauropodomorph dinosaurs dominated the herbivorous niches during the first 40 million
years of dinosaur history (Late Triassic–Early Jurassic), yet palaeobiological factors that …

Fossilized organic remains are important sources of information because they provide a
unique form of biological and evolutionary information, and have the long-term potential for …

The evolution of nest site use and nest architecture in the non-avian ancestors of birds
remains poorly understood because nest structures do not preserve well as fossils …

The goal of paleoproteomics is to characterize proteins from specimens that have been
subjected to the degrading and obscuring effects of time, thus obtaining biological …

The Late Jurassic was a period of great diversity for sauropod dinosaurs, with different
lineages of Neosauropoda flourishing, including several camarasauromorph taxa. Efforts …

Our understanding of pre-Cretaceous dinosaur reproduction is hindered by a scarcity of
evidence within fossil records. Here we report three adult skeletons and five clutches of …

Molecular studies have contributed greatly to our understanding of evolutionary processes
that act upon virtually every aspect of living organisms. However, these studies are limited …
