Scientists have identified ancient octopus fossils belonging to genus Nanaimoteuthis, particularly Nanaimoteuthis haggarti, which may have grown up to 19 meters (62 feet) long—longer than a bus and possibly the largest invertebrate ever recorded. Analysis of 27 fossilized beaks reveals these creatures were apex predators in Cretaceous oceans, using intelligence and crushing bite force to dominate marine ecosystems alongside mosasaurs and plesiosaurs.
