As I was recently doing some research on the prehistoric shark genus Cladodus, I came across some info that classifies the genus as a member of the family Cladoselachidae, Order Cladoselachiformes.

This is somewhat confusing to me as mindat and the Paleontological Database aka fossilworks list Cladodus as a member of the family Ctenacanthidae, Order Ctenacanthiformes.

I'm personally leaning more towards Cladodus being a member of at least the Ctenacanthiformes. But I'm curious what are the origins of this taxonomic confusion on the genus Cladodus's phylogenetic placement in the Chondricthyan family? Is Cladodus a member of the Cladoselachiformes or Ctenacanthiformes?
What do you guys think?
