extinct Voay of Madagascar, around near the Oligocene/Miocene boundary. Within Crocodylus, the mugger crocodile's closest living relatives are the Siamese crocodile and the saltwater crocodile. Fossil crocodile specimens excavated in the Sivalik Hills closely resemble the mugger crocodile in the shortness of the premaxillae and in the form of the nasal openings. In Andhra Pradesh’s Prakasam district, a long fossilized skull of a mugger crocodile was found in a volcanic ash bed that probably dates to the late Pleistocene. Crocodylus palaeindicus from late Pliocene sediments in the Sivalik Hills is thought to be an ancestor of the mugger crocodile. Fossil remains of C. palaeindicus were also excavated in the vicinity of Bagan in central Myanmar. Below cladogram is from a tip dating study, for which morphological, molecular DNA sequencing and stratigraphic fossil age data were simultaneously used to establish the inter-relationships within Crocodylidae. This cladogram was revised in a paleogenomics study. Characteristics Mugger crocodile hatchlings are pale olive with black spots. Adults are dark olive to grey or brown. The head is rough without any ridges and has large scutes around the neck that is well separated from the back. Scutes usually form four, rarely six longitudinal series and 16 or 17 transverse series. The limbs have keeled scales with serrated fringes on outer edges, and outer toes are extensively webbed. The snout is slightly longer than broad with 19 upper teeth on each side. The symphysis of the lower jaw extends to the level of the fourth or fifth tooth. The premaxillary suture on the palate is nearly straight or curved forwards, and the nasal bones separate the premaxilla above. The mugger crocodile is considered a medium-sized crocodilian, but has the broadest snout among living crocodiles. It has a powerful tail and webbed feet. Its visual, hearing and smelling senses are acute. Adult female muggers are on average, and male muggers usually measure between and weigh between . They rarely grow up to . A sample of adult mugger crocodiles from southern India weighed about on average. Large males are reported to weigh up to . The largest known muggers measured . The largest zoological specimen in the British Museum of Natural History measures . One male mugger caught in Pakistan of about weighed . One individual weighing had a bite force of . Distribution and habitat The mugger crocodile occurs in southern Iran, Pakistan, Nepal, India and Sri
