Muensterellidae is a family of stem-octopod cephalopods from the Late Jurassic of Europe. Three genera are currently placed in this family, Muensterella, Celaenoteuthis, and Etchesia.

Phylogeny

Muensterellidae is one of three families in the superfamily Muensterelloidea along with the Patelloctopodidae and Enchoteuthididae. 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.
