This story is amazing.
Giant octopuses of the Cretaceous were up to 19 meters (60 feet) long.
They were the apex ocean predators of their day, eating up plesiosaurs and mosasaurs.
And they were apparently quite intelligent.
Sorry we missed you!

1. Body size estimation of Late Cretaceous octopuses. The graph shows an allometric relationship between the length of the jaw and mantle in long-bodied species of extant finned octopus. The name of the corresponding species is shown along each growth curve. The sizes of N. jeletzkyi and N. haggarti based on their largest specimen are indicated by black vertical lines. Reconstruction of these two species, the extant giant squid, and gigantic vertebrate predators in the Late Cretaceous are shown with their maximum total length.
