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.[1]

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°.[1]

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.[1]
