Notes:
- ^ Here, the Hagfish are treated as a separate clade, as in Sweet and Donoghue's 2001 tree produced without cladistic analysis[1]. However, it has been recognised by some [2] that the hagfish and lampreys may be closer to one another in their own clade, the Cyclostomata.
- ^ The clade Proconodontida is also known as Cavidonti.
- ^ Euconodonta is referred to as "Conodonti" by Sweet and Donoghue[1], although this is not widely used[original research?].
