New evidence moves early giant crocodile further from modern alligator on family tree

An international team of paleontologists, geologists, geoscientists and Earth scientists has found evidence that a type of giant crocodile that lived millions of years ago in what is now North America is not closely related to modern alligators. In their study published in the journal Communications Biology, the group took a closer look at Deinosuchus fossils and those of other species to determine whether it was saltwater-tolerant.
