†Enchoteuthinae Muensterellidae is a family of stem-octopod cephalopods from the Late Jurassic to Late Cretaceous.
Muensterellidae is one of two families in the superfamily Muensterelloidea along with the Patelloctopodidae.
The muensterelloids are characterized by having a roughly spoon-shaped end of the gladius called the patella.
This type of gladius is likely ancestral to the gladius remnants of modern octopuses.
