Declinognathodus is an extinct genus of platform conodonts.

Use in stratigraphy

The Bashkirian, the oldest age of the Pennsylvanian (also known as Upper Carboniferous), contains six biozones based on conodont index fossils, two of which contain Declinognathodus species:

  • the zone of Declinognathodus marginodosus,
  • the zone of Declinognathodus noduliferus.
  • The GSSP point is at Arrow Canyon, Nevada, USA, with the first appearance of Declinognathodus nodiliferus.

    The base of the Moscovian, the second stage in the Pennsylvanian, is close to the first appearances of the conodonts Declinognathodus donetzianus and Idiognathoides postsulcatus. The Moscovian can biostratigraphically be divided into five conodont biozones, one of which contain a Declinognathodus species : the zone of Declinognathodus donetzianus. The GSSP candidate sections are the Ural mountains or in Nashui, Luodian County, Guizhou, China.
