Longirostres is a clade of crocodilians that includes the crocodiles and the gavialids , to the exclusion of the alligatoroids . Defined in 2003 by Harshman et al. , Longirostres is a crown group defined phylogenetically as including the last common ancestor of Crocodylus niloticus Gavialis gangeticus [1]
Traditionally, crocodiles and alligators were considered more closely related and grouped together in the clade Brevirostres , to the exclusion of the gharials . This classification was based on morphological studies primarily focused on analyzing skeletal traits of living and extinct fossil species.[2] DNA sequencing have rejected Brevirostres upon finding the crocodiles and gavialids to be more closely related than the alligators.[1] [3] [4] [5] [6]
Below is a cladogram showing the relationships of the major crocodilian groups based on molecular studies:[5] [6]
