A research team has excavated over 1300 eggshell fossils from the Lower Cretaceous Ohyamashimo Formation of Hyogo Prefecture, Japan. Over 96% of these fossils, including numerous fragments, four partial and almost complete eggs in an in situ nest, belonged to a new ootaxon the authors named Himeoolithus murakamii, attributed to a small non-avian theropod dinosaur. The remaining eggshell fragments, belonging to five additional small theropod ootaxa, showed notable biodiversity.
