       Along with Styletoctopus,‭ ‬the description of Keuppia was one of the big discoveries concerning the study of prehistoric cephalopods.‭ ‬Keuppia has the standard eight arms common to all octopuses yet is not yet a modern form.‭ ‬Inside the body there is what is called a gladius,‭ ‬a firm growth that is actually the remnant of the large outer shells that once surrounded the bodies of its ancestors.‭ ‬In modern octopuses the gladius is greatly reduced to a thin rod-like structure as to not hinder movement into crevices.‭ ‬Keuppia however with its‭ ‬larger gladius would not have been able to squeeze into such tight spaces,‭ ‬and may have been more pelagic‭ (‬living in open water‭) ‬as a result.‭ ‬When studied alongside Styletoctopus however the real significance can be appreciated,‭ ‬since the gladius of Styletoctopus is smaller than Keuppia,‭ ‬but still larger than those seen in modern forms.‭ ‬This indicates a transition from squid or squid-like ancestors,‭ ‬to primitive octopuses like Keuppia,‭ ‬to nearer modern forms like Styletoctopus,‭ ‬before the eventual appearance of today‭’‬s modern octopuses.

Another prehistoric octopus genus discovered from Lebanese fossil deposits is Palaeoctopus.
