Crocodylus thorbjarnarsoni

''Crocodylus thorbjarnarsoni'' is an extinct species of crocodile from the Pliocene and Pleistocene of the Turkana Basin in Kenya. It is closely related to the species ''Crocodylus anthropophagus'', which lived during the same time in Tanzania. ''C. thorbjarnarsoni'' could be the largest known true crocodile, with the largest skull found indicating a possible total length up to . It may have been a predator of early hominins. ''Crocodylus thorbjarnarsoni'' was named by Christopher Brochu and Glenn Storrs in 2012 in honor of John Thorbjarnarson, a conservationist who worked to protect endangered crocodilians.
==Description==
''Crocodylus thorbjarnarsoni'' is distinguished from other crocodiles by its broad snout. It has small raised rims on the prefrontal bones in front of the eyes, a feature also seen in some Nile crocodile individuals. The squamosal bones form raised rims along the sides of the skull table, similar to the crests in ''C. anthropophagus'' but much smaller. Also like ''C. anthropophagus'', it has nostrils that open slightly forward rather than directly upward.〔
The largest ''C. thorbjarnarsoni'' skull found (KNM-ER 1682) measures from the tip of the snout to the back of the skull table, in comparison, the largest known extant ''Crocodylus'' skull is that of a saltwater crocodile, measuring . Based on regression analysis for ''Crocodylus'', this corresponds to a total length of but such analysis have been shown to underestimate the size of very large individuals by as much as 20%, which means it could have been as long as .〔
