Mosirites (IPA: [ˌmɒrsiˈɾaɪtis]) is a genus of anisoceratid ammonite from Hobetsu in Hokkaido; North Japan. The type species is Mosirites mirabilis, known from multiple partial and complete specimens.
Description
Mosirites is known from multiple specimens which were described in 2023 by Shigeta et al., (2023). The holotype, HMG-2412 has a maximum diameter of 325 mm (12.8 in), and consists of a phragmocone and a part of the body chamber with length of about 150°.
Etymology
The generic name, Mosirites (IPA: [ˌmɒrsiˈraɪtɛs]), 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 (IPA: [ˌmiraˈbilis]), is a Latin word for amazing, and refers to its amazing and wonderful form. The second species' specific name, serpentiformis (IPA: [ˌsɛrpɛntiˈfoːrmis]), derives from the Latin words 'serpens' (IPA: [sɛrpɛns]) and 'forma' (IPA: [foːrma]) and refers to its snake-like form.
