We review morphological features of the amniote egg and embryos in a comparative
phylogenetic framework, including all major clades of extant vertebrates. We discuss 40 …

Reptile eggshell ensures water and gas exchange during incubation and plays a key role in
reproductive success. The diversity of reptilian incubation and life history strategies has led …

Knowledge about the types of nests built by dinosaurs can provide insight into the evolution
of nesting and reproductive behaviors among archosaurs. However, the low preservation …

The Gekkota is an important clade in the evolution of calcified eggshells in that some of its
families lay rigid eggshells like archosaurs. However, the fundamental differences and …

Thin fossil eggshell from Upper Cretaceous deposits of Europe, characterized by nodular
ornamentation similar to modern gekkotan eggshell, has mostly been interpreted as …

Raman spectroscopy has been widely used in micropaleontology and organic geochemistry
to identify carbonaceous materials and evaluate their thermal maturity in fossils or …

Abstract The Molí del Baró-1 site (north-eastern Iberia) has yielded one of the richest fossil
assemblages of the continental upper Maastrichtian from western Europe. It includes …

Simple Summary Most previous studies on eggshell mechanics only focused on single
species or taxa and often lacked a side-by-side comparison between eggshell …

Despite over a hundred years of intense paleontological exploration, the terrestrial rocks of
the Upper Cretaceous (Maastrichtian) Hell Creek Formation of eastern Montana are …

Abstract The Add‐my‐Pet collection of data on energetics and Dynamic Energy Budget
parameters currently contains 92 species of turtles and 23 species of crocodiles. We discuss …
