Deinosuchus, the giant crocodile. Measuring 50 feet long from head to tail and weighing up to 9 tons, Deinosuchus is the biggest crocodile that has ever lived.
— Allen, about Deinosuchus

Deinosuchus ("Terrible Crocodile") was a species of giant alligator crocodilian, more closely related to the modern alligators than to the 'proper' crocodiles, from Cretaceous North America. It inhabited the swampy coastal areas of the Western Interior Seaway.

Because of its size and power, Deinosuchus was the top predator of its environment, and most commonly preyed on herbivorous dinosaurs such as Parasaurolophus. It grew up to 15 meters (50 feet) in length and weighed up to 9 tons in weight, making it the largest crocodilian that has ever lived on Earth, larger that Sarcosuchus in size. It was a crocodilian that lived during the Cretaceous period around 8565 million years ago and died out during the K-T mass extinction event.

It lived in what is now the USA and probably Canada. Deinosuchus lurked in the rivers and seas, waiting for big prey to come, but it would also attack smaller creatures. Its prey included Parasaurolophus and its competitor is the theropod dinosaur Albertosaurus, which it could easily fight off to scavenge alreadydead animals.

FactsEdit

Time/Era/PeriodEdit

Deinosuchus lived during the Late Cretaceous period from 85–65 million years ago, living up until the end of the Cretaceous peiord and dying out with the dinosaurs. Most Deinosuchus fossils have been found in parts of Texas were Dallas is today.

Size/DescriptionEdit

Deinosuchus were immensely large creatures. Measuring 50 feet (15.3 m) in length from head to tail and weighing more than 9 tons, as much as a double–decker buss, Deinosuchus was, without a doubt, the largest crocodilian that had ever existed, surpassing the size of Sarcosuchus, and was also one of the largest predators that ever lived on planet Earth. These crocodiles were so huge, they hunted and fed on dinosaurs.

BehaviorEdit

Like the estuarine, or saltwater crocodiles, in Australia and Papua New Guinea in the 21st century, Deinosuchus made forays into open oceans to find food. These giant crocodiles also lived in numbers of five or six individuals and even young, 1 ton Deinosuchus could easily drive even the biggest of Pterosaurs to their death.

On land, like modern crocodilian, Deinosuchus basked on the sandbank and some even had their mouths open. Much like dogs, they panted to actually lose a bit of heat. With their colossal jaws, Deinosuchus was adapted to dragging down huge prey.

In my JournalsEdit

Famous for being known as the 'Giant Crocodile', Deinosuchus was the largest crocodilian that has ever lived. Measuring 50 feet in length and weighing as much as a doubledecker bus, these Cretaceous crocodiles were so immense that they hunted and fed on any prey, from the mightiest pterosaurs to creatures even as big as dinosaurs.

These giant crocodiles also often hunted in the open ocean. With their huge jaws and immense strength, these crocodiles were built to drag huge prey down through the water. It appears that like all crocodile, Deinosuchus bask on the bank. Especially when they are in numbers of several individuals.
