Vampyronassa rhodanica ("vampire fish trap") is an extinct vampyromorph cephalopod known from around 20 fossils from the Lower Callovian (165–164 Ma) of La Voulte-sur-Rhône, Ardèche, France.
[2] This taxon differs from the modern vampire squid in having longer first dorsal arms, a larger hyponome, and a more elongated mantle.
[2] Vampyronassa shares some characters with modern vampire squid Vampyroteuthis, such as lack of ink sac and unique type of sucker attachment.
[2] Although modern vampire squid are deep-sea opportunistic detritivore and zooplanktivore, Vampyronassa is estimated to have been an active predator following a pelagic mode of life according to characteristics of its arms.
[2] Considering Oligocene vampyromorph Necroteuthis probably had a deep-sea mode of life,[3] initial shift of vampiromorphs to offshore environments was possibly driven by onshore competition.
