1. Here, the hagfish are treated as a separate clade, as in Sweet and Donoghue's 2001 tree produced without cladistic analysis.^[2] However, it has been recognised by some ^[3] that the hagfish and lampreys may be closer to one another in their own clade, the Cyclostomata.
2. The clade Proconodontida is also known as Cavidonti.
3. Euconodonta is referred to as "Conodonti" by Sweet and Donoghue,^[2] although this is not widely used.
