Eggshell microstructure and porosity of the Nicobar scrubfowl (Megapodius Nicobariensis, great Nicobar island, India)Géraldine Garcia, Ashu Khosla, Ashok Sahni and Monique Vianey-LiaudKeywords: conductance porosity; eggshell microstructure; incubation conditions; Megapodesdoi: 10.18563/pv.36.1-4.75-88 Abstract The eggshell of Nicobar scrubfowl (Megapodius nicobariensis) is described for the first time. Its egg porosity is calculated and discussed with data from several taxa (another megapode, some extant and fossil reptiles including a titanosaur group) in order to compare incubation types with eggshell structure. Eggshell microstructure reflects first phylogenetic traits and does not seem to have developed major adaptative features due to the incubation conditions, except for the pore canals.

Un nouveau type de coquille d'oeuf présumé Dinosaurien dans la Campanien et le Maestrichtien continental de Provence.Philippe KerourioKeywords: Campanian/Maastrichtian; eggshell microstructure; ProvenceAbstract The discovery of eggshells of ornithoid type is signaled for the first time in the continental Campanian and Maastrichtían of Provence. The taxonomie relationship of these eggshells and their interest in the biostratigraphical study of Upper Cretaceous of Provence are discussed. Article infos Published in Vol. 12, Fasc. 4 (1982) |
