Dendroolithus

Dendroolithus is an oogenus of Dendroolithid dinosaur egg found in the late Cenomanian Chichengshan Formation (Tiantai Group), in the Gong-An-Zhai and Santonian Majiacun Formations of China and the Maastrichtian Nemegt and Campanian Barun Goyot Formation of Mongolia.[1][2] They can be up to 162 mm long and 130 mm wide.[3] These eggs may have been laid by a Therizinosaur, Sauropod, or Ornithopod.[4] The oospecies "D." shangtangensis was originally classified as Dendroolithus, however, it has since been moved to its own distinct oogenus, Similifaveoloolithus.[5] This oogenus is related with embryos of the theropod Torvosaurus[6]
