New type of dinosaur eggs found from Early Cretaceous of Gansu Province, China

Dinosaur eggs from the Lower Cretaceous are worldwide rare as compared to those from Upper Cretaceous deposits. In China, they were only reported in Liaoning Province. In a paper published in the latest issue of Vertebrata PalAsiatica, paleontologists described a new type of dinosaur eggs from the Lower Cretaceous Hekou Group in the Lanzhou-Minhe Basin, northwestern China, and established a new oogenus and a new oospecies, within a new oofamily. This finding has important implications for understanding the diversity and the geological and geographical distribution of Early Cretaceous dinosaur eggs in China, as well as the evolution of dinosaur eggshell structure. —> Read More
