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. IVPP V 31375.2-6, F. V 31376.2, G-H. V 31376.3. Scale bars=200 μm
