Period of life:
Deinosuchus is an extinct genus of crocodilian related to the modern alligator that lived 80 million years ago during the Late Cretaceous period. Deinosuchus two large teeth were first fossils unearthed in North Carolina, a state in the eastern United States, in 1858. Five years later, archaeologists unearthed several osteoderms - bone plates covered the dinosaur back. Deinosuchus was the ancestor of modern crocodiles but significantly exceeded them in body length.
The name of reptile means “terrible crocodile”. Indeed, its length estimated about 12 metres and weight about 5 tonnes. Its jaws contained more than 40 large and robust teeth fitted for crushing even sea turtle shell. Deinosuchus bite force was estimated about 102 000 Newton, while the modern-day crocodile bite force is estimated around 34 000 Newton. It is comparable to Tyrannosaurus jaws strength.
Given that strength western North America Deinosuchus preferred to prey dinosaurs such as Triceratops or Tyrannosaurus. It ambushed prey at the water’s edge and sank into the skin with a deadly grip. Deinosuchus adopted hunting tactics akin to living crocodiles, performing death roll. The dinosaur dragged the prey, submerged it and began spinning it around its axis while dismembering the carcass into pieces. Eastern North America ancient reptiles were smaller and preyed upon turtles, large fish, and small dinosaurs.
Scientists’ research data indicates Deinosuchus 50 year’s lifespan of which 35 years maturing. During this period, crocodiles could observe how generations of one dinosaur species were replaced.
