Species
  • Metapolygnathus" baloghi

  • Metapolygnathus echinatus
  • Metapolygnathus polygnathiformis
  • Metapolygnathus praecommunisti[3]
  • Metapolygnathus primitius

Metapolygnathus is an extinct genus of platform conodonts.

Synonyms

[edit]

Mazzaella is a new genus that also includes Metapolygnathus baloghi Kovacs (1977).

Use in stratigraphy

[edit]

The top of the Carnian or the base of the Norian stages (Late Triassic) begin at the base of the conodont biozones of Metapolygnathus communisti and Metapolygnathus primitius. A global reference profile for the base (a GSSP) had in 2009 not yet been appointed.
