Abstract

Abstract:

Here we report the first dinosaur eggshells found in the Nanhu Gebi of Hami, including Elongatoolithus elongatus and Ovaloolithus oosp. The discovery of these dinosaur eggs not only enlarge the palaeogeographic distribution of elongtaoolithid and ovaloolithid eggs, but also indicate the geological age of egg-bearing strata to be the end of Late Cretaceous. Whether the strata can be correlated with the Subashi Formation in Turpan Basin remains to be clarified.

Key words: Nanhu Gebi, Hami, Xinjiang, Late Cretaceous, dinosaur eggs

摘要：

报道了新疆哈密南湖戈壁首次发现的恐龙蛋,包括长形长形蛋(Elongatoolithus elongatus)和椭圆形蛋未定种(Ovaloolithus oosp.)。这些恐龙蛋的发现不仅扩展了长形蛋类和椭圆形蛋类的古地理分布,而且表明南湖戈壁含蛋岩层地质时代为晚白垩世末期;该地层是否可与吐鲁番盆地的苏巴什组进行对比还有待进一步工作确认。

Fig. 1 Microstructure in radial section of the dinosaur eggshell found in Hami A-E. Elongatoolithus elongatus: A-C. thinner eggshell (0.85-1.12 mm), that is composed of the cone and the columnar layers, with an undistinguished boundary between them, several cones are gathered, with clear cone gaps, and straight tubular pore canals (B); D-E. thicker eggshell (including ornamentation 1.42-1.54 mm), ornamentation of the eggshell is unevenly distributed, with slight differences undulating (E); F-H. Ovaloolithus oosp.: incomplete cone layer, the inner and outer zones of the columnar layer, slender prismatic calcite crystals in inner zone and fan-shaped or pinna-shaped crystals in outer zone, almost straight pore canals (G), unevenly distributed pore canals (H) A-E.
