Eocyprinus is a genus of Eocene-aged cypriniform fish that is probably a cyprinid of the subfamily Barbinae. Fossils were found in the presumed Eocene-aged Sangkarewang Formation, Sumatra, Indonesia. According to the original describer (Sanders, 1934), there were 41 specimens found with one additional specimen (G192-1900) from the Utrecht collections (not verified). All of these specimens are deemed lost thus preventing further studies of the taxa. The original describer wrote several characteristics that distinguish Eocyprinus from other cyprinoids in the Sangkarewang. Those are head length 30% of standard length, dorsal fin with no denticles that have 3 unbrached rays, anal fin with 3 unbranched rays, and three pointed pharnygeal teeth.[1]
