Crocodylus checchiai is an extinct species of crocodile from the Pliocene of Libya and the Miocene of Kenya. C. checchiai was named in 1957 from the . It is similar in appearance to the Nile crocodile C. niloticus and may even be the same species. Remains from the lower in the Turkana Basin of Kenya that were first attributed to the Nile crocodile have now been reassigned to C. checchiai, extending its geographic and temporal range.[1]
A 2018 tip dating study by Lee & Yates simultaneously using morphological, molecular (DNA sequencing), and stratigraphic (fossil age),[2] along with genetic information collected from extinct Voay [3] produced the tree shown below:
