''Acanthoscaphites'' is an extinct genus of cephalopod belonging to the Ammonite subclass. The average diameter of its shell was approximately three fourths of an inch, but some specimens have been found with a diameter of slightly over two inches. ==Classification== ''Acanthoscaphites'' was first described by Schluter in 1872. Subsequent taxonomic revisions may have rendered ''Acanthoscaphites'' synonymous with ''Scaphites'' and ''Trachyscaphites''. Little information is available regarding the validity or synonymy of the Acanthoscaphites genus, so this page may be inaccurate. Please use caution when referring to this article.
