Etymology

The generic name, Mosirites, is derived from the Ainu word for peaceful land or Hokkaido, and the suffix "-ites" which is common in ammonite genera. The type species' specific name, mirabilis, is a Latin word for amazing, and refers to its amazing and wonderful form. The second species' specific name, serpentiformis, derives from the Latin words 'serpens' and 'forma' and refers to its snake-like form.
