Taxonomy
It consists of two species, Keuppia hyperbolaris and Keuppia levante, both of which lived approximately 95 million years ago.[1] Both species were found in fossilized form, which is very uncommon for extinct octopuses, as the soft tissue of dead octopuses almost always disintegrates before it has a chance to fossilize.[2] These fossils, along with those of the genus Styletoctopus, were found from the Cretaceous-age Hâqel and Hjoula localities in Lebanon. The presence of a gladius vestige in this genus shows a transition from squid to octopus in which the inner shell has divided in two in early forms to eventually be reduced to lateralized stylets, as can be seen in Styletoctopus.
