Euthecodon
''Euthecodon'' is an extinct genus of long-snouted crocodyline crocodilians. It was common throughout much of Africa during the Neogene, with fossils being especially common in Kenya. It existed from the Early Miocene to the Early Pleistocene.
==Description==
''Euthecodon'' was large for a crocodilian. One specimen, LT 26306, found from the Turkana Basin, was estimated by skull length to have been around 10m long.〔Storrs, G. W. (2003). Late Miocene-Early Pliocene crocodilian fauna of Lothagam, southwest Turkana Basin, Kenya. In: ''Lothagam: The Dawn of Humanity in Eastern Africa'' pp. 137–159. New York. Columbia University Press. ISBN 0-231-11870-8.〕 It had a narrow rostrum that was unusually elongate with deeply scalloped dorsal margins. The skull table, however, was proportionally small and is almost square in shape. The jaws were lined with isodont, or slender, similarly sized and shaped, teeth. Unlike nearly all other crocodilians, ''Euthecodon'' possessed only four premaxillary teeth. Because they are sharp and bicarinate, they are believed to have been an adaptation for a piscivorous feeding habit, or a diet that included fish.
