Alligator mcgrewi is an extinct species of alligator described by K.P. Schmidt in 1941. They lived in the Early Miocene period,[2][3] and their range was principally in what is now Nebraska, United States.[2] It is a small alligator with an estimated body length of 1.6 metres (5.2 ft).[4] The Alligator mcgrewi has a unique snout, distinguishing it from other alligator species. This special feature suggests that A. mcgrewi evolved from specific environmental adaptations.
