This is the first time that the fossil egg and embryo of Therizinosaurs have been exhibited in Japan.
　There were 2 cases at the both side, but it was difficult to take pictures by the insect glasses equipped above!

　Therizinosaurs are bipedal dinosaurs which are medium-sized, and seem to be plant-eaters. The hands equip with very large and sharp claws which reached to more than 60cm.
