Crocodiles are more closely related to birds and dinosaurs than to most animals classified as reptiles (though all of these are thought to probably be more closely related to each other than to Testudines (turtles and tortoises), and have correspondingly unusual features for reptiles, such as a four-chambered heart.
In this latter crocodile it was actually the skin that was measured by zoologist Jerome Montague, and as skins are known to underestimate the size of the actual animal, it is possible this crocodile was at least another 4 inches (10 cm) longer.

 American Crocodile - Wikipedia, the free encyclopedia
The American Crocodile (Crocodylus acutus) is the only New World crocodile and the top predator in its range.
Like all crocodiles it is a quadruped, with four short, splayed legs; a long, powerful tail; a scaly hide with rows of ossified scutes running down its back and tail; and mighty jaws.
Due to hide hunting, pollution, and loss of mangrove habitat, the American Crocodile was listed as endangered in 1975 and towards the end of the 20th century the species bordered near extinction, numbering fewer than 400.
