There is hardly such a thing as a true crocodile in South America.

The Australian alligator, as it is usually called, is a true crocodile, identical, according to Mr. Gray, with the common Indian species.

There is much interest connected with the discovery of the existence of the true crocodile (C. acutus) in the Floridian peninsula.

At that time science was blind to the fact that the true crocodile was a member of the fauna of the United States.

Of the true crocodiles there are five species known.

The Crocodilians also appear in the later Triassic, abound in the Jurassic, and give way before the later types, the true Crocodiles, in the Cretaceous.
