Elongatoolithus chichengshanensis

† Elongatoolithus chichengshanensis is an oospecies of oviraptorosaurian eggs from the Late Cretaceous Chichengshan Formation of Zhejiang Province, China. Named for its type formation, these elongated eggs represent a distinct ootaxon within the diverse elongatoolithid assemblage of southern China. The Zhejiang egg-bearing strata have yielded extraordinary abundances of dinosaur eggs from multiple oospecies, facilitating comparative studies of Cretaceous reproductive biology. Their precise attri
