Harranahynchus
''Harranahynchus'' is an extinct new genus of sclerorhynchid (Family Sclerorhynchidae) sawfish from the late Maastrichtian deposits of the Muwaqqar Chalk Marl Formation of Harrana in Jordan. The genus is so far represented by a single species, ''Harranahynchus minutadens''〔Kaddumi, H.F. (2009). A new genus and species of sawfishes (Chondrichthyes: Batoidea) from the late Maastrichtian sediments of Harrana. In: Fossils of the Harrana Fauna and the Adjacent Areas. Publications of the Eternal River Museum of Natural History, Amman. pp 178-187〕 and named after its minute rostral and dental battery teeth that do not exceed two millimeters in length, a size that is significantly smaller than the rostral teeth of any other modern or extinct sawfish species. Harranahynchids were medium-sized benthic predators around 2-2.5 meters in length and lived in the shallow offshore subtropical marine waters of the southern Tethys Ocean〔 alongside other sclerohynchid sawfishes such as ''Schizorhiza stromeri'' Weiler, 1930.
