Microstructural and geochemical analyses of the dinosaur eggshells at La Cairanne (Aix en Provence Basin, Lower Rognacien) show the presence of diagenesis. Diagenetic processes have altered the thickness of the shells and some structural data. The chemical composition has been also modified. Thus it is difficult to use these parameters to reconstruct the paleoenvironment. It is possible, indeed probable, that the problems of the previous authors about the definitions of eggshell morphotypes in…

Microstructure and chemical composition of giant avian eggshells
XANES studies confirm the active role of sulfated acidic polysaccharides in biomineralisation processes of carbonate skeletons and show that sulfur is associated with amino acids in the inner organic membranes, whereas in the mineralised layers the sulfur is mainly associated with sulfated poly Saccharides.


Paleobiological and isotopic studies of eggshells from a declining dinosaur species
It is concluded that in the late Maastrichtian populations of “Hypselosaurus,” pathologic eggshells were caused by hormonal imbalances of the vasotocin and of the estrogen levels, and postulated that the teratological shell repetition led to embryo suffocation and that the pathological reduction in shell thickness caused shell breakage and dehydration of the embryo.
Factors Affecting the Aragonite: Calcite Ratios in Carbonate-Secreting Marine Organisms
The effect of temperature on skeletal carbonate mineralogy is investigated. The mineralogical determinations are based on X-ray analyses. Organisms marked by a large increase in aragonite over
