Abstract

This report is about the first record of non-avian dinosaur eggs in the Hefei Basin, Anhui Province, China. Based on the combination of elongated egg body, linear ridges on the outer surface and two structure layer, the eggs can be referred to Elongatoolithidae. The gradual boundary between the cone and the column layers as well as the relative thin eggshell (less than 1 mm) indicates its affinity within Elongatoolithus. The eggs are identified as Elongatoolithus oosp., as they were severely compressed and experienced erosion on both inner and outer surfaces. The discovery of egg fossil in the Hefei Basin offers evidence for stratum comparison in this region and supplements the diversity of egg fossils in Anhui. Meanwhile, this discovery also enriches the paleogeographic distribution of elongatoolithids.
