Diagnosis
ReferenceDiagnosis
Q. Wang et al. 2012Small spheroid or nearly spheroid eggs, irregularly arranged in the nest. Eggshell thickness, 2.4–4.0 mm. Outer surface of the eggshell is coarsely decorated. Cone layer is thin with 0.18–0.25 mm thick, about 1/20–1/4 of eggshell thickness. Three distinct zones of the columnar layer: (1) Horizontal growth lines develop in the inner zone. (2) Light and dark bands with varying thickness and lengths develop in the medial zone. (3) Secondary eggshell units are loosely arranged in the outer zone. The pore cannel is irregular.
