The University of Tsukuba in Ibaraki Prefecture, Japan, announced that a research team discovered the smallest dinosaur egg fossil ever found in the world in Japan.
It is reported that scientific researchers discovered an oval-shaped dinosaur egg in the Mesozoic and Peregrine sediments on the outskirts of Tanba City, Hyogo Prefecture, southwest Japan. Its length and width were 4.5 cm and 2 cm respectively. This egg is about 110 million years old.
A joint research team from the University of Tsukuba in Japan, the Hyogo Prefectural Museum of Man and Nature and the University of Calgary in Canada is responsible for the excavation and research work. Researchers believe that this unique dinosaur egg belongs to the small, ferocious carnivorous dinosaurs of the theropod suborder, to which Tyrannosaurus rex also belongs. The research team inferred based on the density of fossil distribution and the remains of dinosaur egg shells that they encountered a nest of small dinosaurs in Damba City.
