<br />ABSTRACT. This first attempt to summarize knowledge on the eggshell structure in amniotic vertebrates, and in particular, the global diversity of the fossil remains, is based on original observations, and employs advanced microscopic techniques. The nomenclature, terminology, nature of eggshell biocrystalline matter and regularities of biomineralization are discussed in detail. Various classifications, based on different levels of eggshell matter organization (ultrastructure, microstructure and general morphology), are also considered. It is argued that basic (ultrastructural) types, microstructural morphotypes, types of pore system and types of surface ornamentation should be employed as the main structural categories in systematic description.
<br />A systematic section includes descriptions of all main fossil egg groups. Fourteen parafamilies and 32 paragenera of dinosaur and Cretaceous avian egg remains are considered, and a comparative review is provided for all the material (18 paragenera and 42 paraspecies) known from Asia. A full listing of known fossil egg parataxa is given in an appendix.
