Cretaceous Age through to the Eocene Age 

Crocodiles are reptiles belonging to the order Crocodylia. They have been around for millions of years and have evolved into various species over time. During the Cretaceous Age, several crocodile species inhabited the Hell Creek Formation.

During the Cretaceous Age, which lasted from approximately 145 to 66 million years ago, the Hell Creek Formation in the United States was home to a diverse range of species, including crocodiles. The Hell Creek Formation is located in parts of Montana, North Dakota, South Dakota, and Wyoming, and it represents a terrestrial environment that existed during the Late Cretaceous period.

Among the crocodiles that inhabited the Hell Creek Formation, Deinosuchus stands out as one of the most famous. Living during the Late Cretaceous period, Deinosuchus was a colossal predator and one of the largest crocodile-like reptiles ever known. Some individuals reached lengths of up to 40 feet (12 meters). It had a sturdy, muscular body, a long snout filled with sharp teeth, and powerful limbs adapted for both swimming and walking on land. As an apex predator, Deinosuchus likely preyed upon dinosaurs and other large animals, dominating its ecosystem.

Another species, Borealosuchus, was a medium-sized crocodile that lived alongside Deinosuchus. Measuring approximately 10–15 feet (3–4.5 meters) in length, Borealosuchus had a more slender build and a long, tooth-filled snout, indicating that it primarily hunted fish and other small vertebrates.

The third species, Leidyosuchus, was smaller, reaching lengths of around 6–8 feet (1.8–2.4 meters). It had a broad, rounded snout with blunt teeth, suggesting a diet focused on mollusks, crustaceans, and other small aquatic organisms.

Together, these three species illustrate the diversity of crocodilian life in the Hell Creek Formation, ranging from massive apex predators to smaller, specialized hunters, each occupying a distinct ecological niche during the Late Cretaceous.
