Did Octopuses Predate Dinosaurs? A 330-Million-Year-Old Octopus Fossil Discovered in Montana

In the tapestry of ancient marine life, a recent revelation has redefined our understanding of cephalopod evolution. The unearthing of a 330-million-year-old fossil in Montana has thrust the origins of octopuses into the spotlight, challenging established notions about their existence in prehistoric times.

This extraordinary find, concealed within the Bear Gulch limestone formation, unveils a chapter in the history of life on Earth that predates even the reign of dinosaurs. The fossil, measuring a modest 4.7 inches and adorned with 10 limbs—two more than the contemporary octopus—stands as a testament to the marvels of ancient biology.

Its well-preserved form, ensconced in limestone, remained dormant for decades, nestled among other fossilized relics until keen-eyed paleontologists deciphered its significance. Named Syllipsimopodi bideni in homage to President Joe Biden, this ancient cephalopod now holds the distinction of being the oldest known ancestor of octopuses.

Christopher Whalen, co-author of the revelatory study published in Nature Communications, underscores the rarity of soft tissue fossils and the profound implications of this discovery. The fossil’s striking similarity to modern octopuses, with ten limbs and evidence of an ink sac, unveils intriguing parallels in the evolutionary trajectory of these enigmatic creatures.

Moreover, this ancient vampyropod, as it is believed to be, not only redefines the origins of octopuses but also blurs the lines between their evolutionary cousins—the vampire squid. This discovery challenges the established timelines, pushing back the ancestry of these creatures by millions of years and urging a reconsideration of their evolutionary journey.

The significance of this finding stretches beyond the confines of its age; it beckons us to reevaluate the mysteries of ancient seas and the enigmatic creatures that once roamed them. It serves as a testament to the relentless pursuit of knowledge and the revelations that await those who delve into the depths of our planet’s history.

As this ancient cephalopod takes its place in the annals of paleontological significance, it stands as a symbol of our quest to unravel the mysteries of our planet’s past and the unwavering curiosity that propels us ever forward into the realms of discovery.
