Blochius is an extinct genus of prehistoric billfish from the Eocene. It is the only genus of the family Blochiidae. It was described by Giovanni Serafino Volta (1764-1842) in 1800. It is only known from the Monte Bolca deposits in Italy, and was likely restricted to shallow, tropical waters of the Tethys Sea.[1]

Description

Blochius was about 60 cm long and had a very slender elongated body, a narrow head with elongated upper and lower jaws and large eyes. Much like its modern relatives such as swordfish, it had an elongated rostrum.[1][2]
