Iapetonudus is an extinct genus of conodonts.
Like other members of its genus, Iapetognathus fluctivagus had ramiform (branching) array of elements (apparatus). It is believed that the ramiform apparatus in Iapetognathus fluctivagus evolved from the coniform (cone-like) apparatus of Iapetonudus ibexensis.
