Scientists discovered fossil jaws from giant octopuses that lived 100-72 million years ago in the Cretaceous Pacific, revealing apex predators up to 20 meters long with wear patterns indicating aggressive hunting of hard-shelled prey, providing a possible biological basis for kraken legends.
Scientists discovered that massive titanosaurs couldn't incubate their eggs by sitting on them, so they used a crocodile-like strategy instead. Analysis of microscopic pores in fossilized eggshells found in cool southern Argentina reveals these giant dinosaurs buried their eggs in decomposing vegetation to generate heat for hatching.
