Step into the heart of prehistoric mystery at the Hell Creek Formation, a legendary treasure trove of fossils left in the wake of the asteroid that rewrote Earth's history at the close of the Cretaceous Period. Spanning Montana, Wyoming, South Dakota, and North Dakota, this 175-metre-thick layer of ancient earth holds secrets that date back 66 million years, capturing the final chapter of the age of dinosaurs. This is the very spot where the fearsome T-Rex was unearthed in 1902, and where the 'Dragon King,' the largest Triceratops skull ever found, came to light.

Beyond the titans of old, the Hell Creek Formation is a panoramic snapshot of an ancient world, giving us a huge array of invertebrates, plants, mammals, fish, reptiles and marine animals frozen in time.
