Abstract: As dinosaurs were oviparous animals, incubation of their eggs was the essential procedure during their reproduction. Physiologically, eggshell microstructures were bound to adapt to the nest environments during incubation if embryos normally developed. Gas conductance estimated from eggshell morphology can provide evidence for the environment conditions in nests. Seymour (1979) first estimated gas coaductance of dinosaur eggs from France and Mongolia and indicated that the nest environments of these eggs were all high in humidity, low in oxygen and high in carbon dioxide. Such conditions most likely occurred underground or within incubation mounds. Williams et al. (1984) found similar nest environments of four kinds of dinosaur eggs from Aix Basin in southern France.
Some papers about dinosaur eggs indicated that the extinction of dinosaurs would be related to their reproduction (Erbcn, 1970; Erben, Hoeffs et al. 1979; Zhao, 1978; Zhao, Ye et al. 1991). Thus further investigations about reproduction of dinosaurs in Late Cretaceous might be significant. This paper will reconsider the relationship between dinosaur eggs and their environments.
