Siphonodella is an extinct genus of conodonts.

Siphonodella banraiensis is from the Late Devonian of Thailand.Siphonodella nandongensis is from the Early Carboniferous of the Baping Formation in China.

The Tournaisian, the oldest age of the Mississipian (also known as Lower Carboniferous) contains eight conodont biozones, two of which are characterized by Siphonodella species:

The GSSP Golden Spike for the Tournaisian is in La Serre, Montagne Noire, France with the first appearance of Siphonodella sulcata. In 2006 it was discovered that this GSSP has biostratigraphic problems.
