Crocodylus falconensis is an extinct species of crocodile known from the early Pliocene of the lower part of the Vergel Member of the San Gregorio Formation of Venezuela. C. falconensis was named in 2013 and it is thought to be the basalmost known Neotropical crocodile species. The cladogram below follows the topology from Scheyer et al. (2013).[1]

A 2018 tip dating study by Lee & Yates simultaneously using morphological, molecular (DNA sequencing), and stratigraphic (fossil age) data established the inter-relationships within Crocodylidae.[2] In 2021, Hekkala et al. were able to use paleogenomics, extracting DNA from the extinct Voay, to better establish the relationships within Crocodylidae, including the subfamilies Crocodylinae and Osteolaeminae.[3]
The below cladogram shows the results of the latest study, with C. falconensis at the base of an Africa+Americas clade of crocodiles within the genus Crocodylus:
