Dendroolithusis anoogenusofDendroolithiddinosaur eggfound in thelate CenomanianChichengshan Formation(Tiantai Group), in theGong-An-ZhaiandSantonianMajiacun FormationsofChinaand theMaastrichtianNemegtandCampanianBarun Goyot FormationofMongolia.[1][2]They can be up to 162 mm long and 130 mm wide.[3]These eggs may have been laid by aTherizinosaur,Sauropod,orOrnithopod.[4]The oospecies"D." shangtangensiswas originally classified asDendroolithus,however, it has since been moved to its own distinct oogenus,Similifaveoloolithus.[5]This oogenus is related with embryos of the theropodTorvosaurus[6]
