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.
