I can share a quick update based on recent reporting.
- Nanaimoteuthis is a genus of Late Cretaceous octopuses known mainly from fossil beaks, with new analyses suggesting they reached impressive sizes and may have been active open-water predators.[1][4]
- Recent coverage describes Nanaimoteuthis haggarti as possibly among the largest known cephalopods, with estimates ranging from about 6.6 to 18 meters in total length, though some researchers question the upper end of those sizes. A related set of pieces highlights beak-based evidence reinterpreting their ecology and predatory behavior, potentially indicating fins and specialized jaw wear patterns consistent with hunting hard prey.[3][5][1]
- Commentary in several outlets frames Nanaimoteuthis as a "Cretaceous Kraken" that reshapes views of ancient marine ecosystems by showing giants among soft-bodied cephalopods, while noting remaining uncertainties about exact anatomy, fin shape, and swimming style.[4][5][3]
If you’d like, I can pull together a concise timeline of the key discoveries and summarize how beak fossils inform estimates of size and predatory behavior, with quick citations.
