Giant Gharial

The giant gharial is the largest of the crocodile-like reptiles on Earth. They are native to much of Brazil and Africa, but has since established nonnative ranges across the Canary Islands of Europe/Africa. They fill the similar niche to both giant alligators and true gharials, being predators that hunt animals as large as sauropods (both modern ones like American giraffe beasts and Asian giraffe beasts and prehistoric ones like Argentinosaurus, etc) and feed on fish including sharks and relatives, as well as bony fishes.
