The Hell Creek Formation is a geologic formation found in the western United States, particularly in Montana, North Dakota, South Dakota, and Wyoming. Here's a detailed description of the Hell Creek Formation:

**Age and Period**: The Hell Creek Formation dates to the Late Cretaceous period, specifically spanning the Maastrichtian stage, approximately 66 to 68 million years ago. It is one of the last geological formations of the Mesozoic Era, just before the Cretaceous-Paleogene (K-Pg) extinction event.

**Geographical Extent**: The formation is primarily found in the northern Great Plains region of North America. It extends across parts of Montana, North Dakota, South Dakota, and Wyoming, covering a vast area.

**Stratigraphy**: The Hell Creek Formation is part of the Fort Union Group and sits above the Fox Hills Formation and below the Tullock Formation. It is characterized by a sequence of sedimentary rocks, including sandstone, siltstone, mudstone, and lignite.

**Paleontological Significance**: The Hell Creek Formation is renowned for its rich fossil record, especially of Late Cretaceous terrestrial vertebrates. It has yielded fossils of dinosaurs such as Tyrannosaurus rex, Triceratops, Ankylosaurus, Edmontosaurus, and many others. It also contains fossils of crocodiles, turtles, mammals, and plants, providing a detailed snapshot of the ecosystems that existed just before the extinction event.

**Paleoenvironment**: During the Late Cretaceous, the Hell Creek area was characterized by a warm and humid climate with extensive river systems, floodplains, and forests. The environment supported a diverse range of plant and animal life.

**Discovery and Research**: The Hell Creek Formation has been extensively studied by paleontologists for over a century. It has provided crucial insights into the last days of the dinosaurs and the immediate aftermath of the K-Pg extinction event, which marked the end of the Mesozoic Era.

**Impact of K-Pg Extinction**: The uppermost layers of the Hell Creek Formation contain evidence of the catastrophic event that led to the extinction of the non-avian dinosaurs, including the famous iridium-rich layer that marks the K-Pg boundary.
