Masakatsu Shimoda was born in the Hyogo prefecture in 1967. From a young age, the artist has always enjoyed drawing and believes that all he needs for a fulfilling life is a set of colored pencils and a sewing machine. In 2011, Shimoda San visited an anthropology museum and saw dinosaur skeletons for the first time, which made a strong impression on him. After viewing the exhibit, he couldn't find any souvenirs at the museum shop that matched his new interests at all. Upon returning home empty-handed, Masakatsu Shimoda decided to embark on a project related to dinosaurs.
