“National Geographic’s” new film “Sea Monsters” is making waves — just not in Mississippi. Funded in part by a grant from the National Science Foundation, the film dives deep into the prehistoric oceans that once covered North America, exploring ancient creatures believed to have inspired legends like the Loch Ness Monster.

Roughly 80 million years ago, areas like Kansas were submerged beneath a vast inland sea, where giant marine reptiles roamed. The movie blends scientific discovery with legend, shedding light on the real-life creatures behind age-old myths. For anyone who grew up fascinated by dinosaurs or sea serpents, this one might stir up some serious nostalgia.
