Eoconodontus
Eoconodontus is an extinct genus of conodonts of the Late Cambrian. It is a two-elements genus from the Proconodontus lineage.Use in stratigraphy
It is suggested that Eoconodontus notchpeakensis can be a marker of the Stage 10 of the Furongian the fourth and final series of the Cambrian.
In 2006, a working group proposed the first appearance of Cordylodus andresi. Currently the first appearance of E. notchpeakensis is favored by many authors because it is globally widespread and is independent of facies.
The Eoconodontus notchpeakensis proposal would also incorporate a non-biostratigraphic marker to correlate the beginning of Stage 10 globally. A carbon isotope excursion occurs in the lower part of the E. notchpeakensis range.
