Kraken of the Cretaceous: 19-meter octopus reshapes deep-sea giants lore

Paleontologists revisited the size of the Late Cretaceous giant octopus Nanaimoteuthis haggarti and now estimate it could reach about 7–19 meters, potentially making it the largest non-colonial invertebrate and a distant relative of modern deep-sea octopuses; initially misclassified as a vampire squid, the species was re-identified from jaw fossils on Vancouver Island and in Japan, with its North Pacific 84-million-year-old habitat and deep-sea lifestyle raising questions about size estimates and octopus evolution.

Giant Late-Cretaceous octopus rewrites ocean size records

Researchers re-evaluate 2008 fossils from Vancouver Island and Japan, reclassifying Paleocirroteuthis haggarti as Nanaimoteuthis haggarti and estimating a jaw‑based body length of 7–19 meters, potentially making it the largest non‑colonial invertebrate and a major Late Cretaceous predator; this deep‑sea cirrate octopus likely preyed on ammonites and is linked to modern dumbo and flapjack octopuses, though some scientists question the size estimates.

Ruling the Reefs: 19-Meter Cretaceous Kraken Unearthed

A Science study using Digital Fossil Mining reveals Nanaimoteuthis haggarti giant octopuses, potentially up to 19 meters, as apex predators in the Late Cretaceous, with beaks found in rocks and wear patterns on jaws suggesting hard-shell/bone crushing and possibly advanced cognition, indicating invertebrates shared top-predator status with mosasaurs and other marine reptiles.
