Greenland sharks have existed for hundreds of millions of years through their ancient lineage while Saturn’s iconic rings are believed to have formed far more recently, possibly only 10 to 100 million years ago.
That means sharks were already swimming in Earth’s oceans long before Saturn wore its most famous feature.
I read just yesterday in another comment here that the Appalachian Mountains are older than sharks.
Sharks showed up in the fossil record at about the same time the Appalachian mountains stopped their mountain building activity, 450 mya.
