I want to go there‼️🦖Museum
Mikasa City Museum, located in Mikasa City, Hokkaido, is a unique museum where the memories of the ancient sea and the history of modern coal mining intersect. The museum displays about 600 fossils (120 species) of ammonites that lived in the Cretaceous period about 100 million years ago, and boasts one of the largest collections in Japan. In particular, the largest ammonite specimen in Japan, measuring about 1.3m in diameter and weighing about 580kg, is a spectacular sight. In addition, the museum also displays the fossil of the "Ezomikasaryu", a type of mosasaurus discovered in Mikasa City, and a full-body skeleton replica of an Allosaurus with a body length of 10m, making it a must-see spot for dinosaur lovers. In addition, you can learn about the history of Mikasa City's development and development, including materials related to the Sorachi Penal Colony established in the Meiji era and machinery and tools used at the Horonai Coal Mine. 
There is an "open-air museum" area outside the building, where you can actually see the boundary between the Ikushunbetsu Formation, which is about 50 million years old, and the Mikasa Formation, which is 100 million years old.
You can have a valuable experience of experiencing the dynamic history of the earth while walking along the maintained promenade. 
Mikasa City Museum is a facility that can be enjoyed by families as well as those interested in fossils, geology, and the history of coal mining.
Why not feel the eternal time in this place where nature and history blend together?
