河南中国中部上白垩统恐龙蛋沉积由高到低分为三个组：高沟、马家村和寺沟。高沟组属于冲积扇沉积，含有Faveoloolitus、Dendroolitus、Dictyoolitus、Parfereroolitus和Longiteresoolitus的恐龙蛋化石组合。马家村组为辫状河-曲流河沉积，发育卵橄榄石、副橄榄石、扁橄榄石、树橄榄石、棱柱橄榄石、稀有杨橄榄、南海云橄榄等组合。四沟组为浅湖湖相-低弯度河相沉积岩，组合为大橄榄石、伊隆古利石、卵橄榄和副橄榄石。到目前为止，已区分出37个卵种、13个卵属和8个卵形恐龙蛋。原生恐龙蛋保存在泛滥平原沉积中，而异地恐龙蛋和副原生恐龙蛋保存在冲积扇中。这表明，河流泛滥平原是保存大量原生恐龙蛋的最佳环境。大多数恐龙蛋保存在棕色到红色的钙质古土壤、泥质粉砂岩或泥岩中，表明筑巢地区的古气候是半干旱的。灰色和绿色泥岩和煤层的存在表明，白垩纪中晚期存在短暂的亚湿润气候。这一气候条件有利于植被环境中曲流河的发育。
The Upper Cretaceous dinosaur egg-bearing deposits in Henan Province, central China are divided into three formations in ascending order: Gaogou, Majiacun and Sigou. The Gaogou Formation belongs to alluvial fan deposits containing the fossil dinosaur egg assemblage of Faveoloolithus, Dendroolithus, Dictyoolithus, Paraspheroolithus and Longiteresoolithus. The Majiacun Formation is interpreted as braided stream to meandering stream deposits with assemblage of Ovaloolithus,Paraspheroolithus,Placoolithus,Dendroolithus,Prismatoolithus, rare Youngoolithus and Nanhiungoolithus. The Sigou Formation is shallow lacustrine/palustrine to low-sinuosity river sedimentary rocks with assemblage of Macroolithus,Elongatoolithus, Ovaloolithus and Paraspheroolithus. To date, 37 oospecies, 13 oogenera and 8 oofamilies of dinosaur eggs have been distinguished. Autochthonous dinosaur eggs are preserved in the floodplain deposits, whereas allochthonous and parautochthonous dinosaur eggs are preserved in the alluvial fans. This suggests that river floodplains are the best environments for the preservation of numerous autochthonous dinosaur eggs. The preservation of most dinosaur eggs in brown to red calcic palaeosoils, muddy siltstones or mudstones suggests that the paleoclimate of the nesting area was semiarid. The presence of gray and green mudstone and coal layers, however, indicates that there existed an ephemeral subhumid climate during the middle and Late Cretaceous. It is suggested that such a climate was favorable for the development of meandering streams in a vegetated environment.
