The Hell Creek Formation is a dig site in Jurassic World Evolution.

InGen Database Description

The Hell Creek Formation is one of the most famous (and most studied) dinosaur fossil sites in the world. It's spread across Montana, North and South Dakota, and Wyoming. It's named for the exposures found along Hell Creek near Jordan in Montana. The formation sits below the Fort Union Formation and above the Fox Hills Formation. Fossil remains span the Maastrichtian stage of the Late Cretaceous and the Danian stage of the Paleogene, 65 million years ago.

The rock strata are mostly claystone and mudstone, with some sandstone. Crocodilian remains indicate a subtropical climate and a region of coastal plains, floodplains, and extensive rivers and pools. These ran into the Western Interior Seaway, a large inland sea that divided the North American continent during the mid-Cretaceous to early Paleogene period.

The Museum of the Rockies in Bozeman, Montana contains the greatest collection of fossils from the formation in the world.

Beyond the numerous dinosaur finds, invertebrate, amphibian, fish, reptile, turtle, lizard, snake and mammal fossils have been recovered here.

Trivia

  • The Hell Creek Formation previously appeared in Jurassic Park: Operation Genesis, considered by many to be Jurassic World Evolution's spiritual predecessor.
