Vědci přehodnotili původ fosilie chobotnice Pohlsepia mazonensis, která byla zařazena mezi nejstarší své řady, a po novém vyhodnocení zjistili, že obsahuje více zubních prvků, než je obvyklé u chobotnic, což vedlo k vyvrácení jejího prvohorního původu a jejímu odebrání rekordního titulu v Guinnessově knize. #fossil #evolution #cephalopod
A study of jaw fossils discovered in Japan and Canada suggests that giant octopuses may have existed as colossal predators in the Cretaceous seas while dinosaurs ruled the land, challenging the prevailing view of marine ecosystems during that era. #MarineLife #Paleontology #Cephalopods #JP #CA
A study led by Hokkaido University suggests that during the reign of dinosaurs, colossal giant octopuses, potentially reaching lengths of up to 20 meters, dominated the Cretaceous seas, as evidenced by fossilized jaw fragments analyzed through advanced technology, challenging the prevailing notion of marine ecosystems being primarily led by large marine reptiles. #DinosaurEra #Cephalopods #FossilResearch #JP #CA
