Crocodylus is a genus of true crocodiles in the family Crocodylidae.
Taxonomy
The generic name, Crocodylus, was proposed by Josephus Nicolaus Laurenti in 1768.[1] Crocodylus contains 13–14 extant (living) species and 5 extinct species. There are additional extinct species attributed to the genus Crocodylus that studies have shown no longer belong, although they have not yet been reassigned to new genera.[2]
Extant species
The 13–14 living species are:

Fossils
Crocodylus also includes five extinct species:[2]
- † Crocodylus anthropophagus is an extinct crocodile from Plio-Pleistocene of Tanzania.
- † Crocodylus checchiai is an extinct crocodile from Late Miocene of Kenya.
- † Crocodylus falconensis is an extinct crocodile from Early Pliocene of Venezuela.
- † Crocodylus palaeindicus is an extinct crocodile the Miocene to the Pleistocene of southern Asia.
- † Crocodylus thorbjarnarsoni is an extinct crocodile from Plio-Pleistocene of Kenya.
Evolution
Crocodylus likely originated in Africa and radiated outwards towards Southeast Asia and the Americas,[5] although an Australia/Asia origin has also been considered.[6] Phylogenetic evidence supports Crocodylus diverging from its closest recent relative, the extinct Voay of Madagascar, around 25 million years ago, near the Oligocene/Miocene boundary.[5]
Phylogeny
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.[7] 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.[5]
