摘要	The Early Cretaceous outcrops in Gansu Province, northern China, have yielded numerous dinosaur skeleton remains and tracks; however, fossil eggs have not been reported in literatures. Here, we describe a new type of dinosaur eggs from the Lower Cretaceous Hekou Group in the Lanzhou-Minhe Basin, representing a new oogenus and a new oospecies, attributed to a new oofamily. The new specimen can be distinguished from other known dinosaur eggs by the combination of the following eggshell micro-features: branched eggshell units lacking a compact layer near the outer surface; interlocking or isolated multi-angular eggshell units, as viewed in tangential sections; and irregular pore canals. Dinosaur eggs from China largely come from the Late Cretaceous deposits, with occasional reports from the Early Cretaceous in Liaoning Province, northeastern China. The new discovery expands the geological and geographical distribution of the fossil record of dinosaur eggs in China and may reveal the origin of eggshell microstructures of spheroolithid eggs.
