Other fossil species from Africa are retained in "Crocodylus" and appear to be closely related to the Nile crocodile: namely "C. checchiai" from the Miocene in Kenya, "C. anthropophagus" from Plio-Pleistocene Tanzania, and "C. thorbjarnarsoni" from Plio-Pleistocene Kenya. While "C. checchiai" was about the same size as the larger modern Nile crocodiles, and shared similar physical characteristics to the modern species; "C. anthropophagus" and "C. thorbjarnarsoni" were both somewhat larger, with projected total lengths up to . Also "C. anthropophagus" and "C. thorbjarnarsoni", as well as "Rimasuchus" spp., were all relatively broad-snouted, as well as large, indicating a specialization at hunting sizeable prey, such as large mammals and freshwater turtles, the latter much larger than any in present-day Africa. Based on morphology, time, and placement of fossils, "C. checchiai" are thought to essentially form a link between the Nile crocodile and today's Neotropical crocodiles. The Nile crocodile apparently is more closely related to the crocodiles of the Americas, namely the American ("Crocodylus acutus"), Cuban ("Crocodylus rhombifer"), Morelet's ("Crocodylus moreletii"), and Orinoco crocodiles ("Crocodylus intermedius"), than to the West African crocodile or other extant African crocodilians. Dispersal across the Atlantic is thought to have occurred 5 to 6 million years ago.
