Archaeus is an extinct genus of marine jackfish from the Paleogene of Europe, where it inhabited the former Paratethys Sea. The oldest species, A. oblongus is from the early Ypresian epoch of Eocene Turkmenistan, and the last species, A. glarisianus and A. solus, are from the early to middle Rupelian, of the Oligocene lagerstatten of Canton Glarus, Switzerland and the Pshekha Formation of North Caucasus, Russia.[1][2]

In life, Archaeus species would have resembled a small trevally, though, Archaeus had a proportionally smaller mouth, and larger eyes, and the tail was more fan-shaped, rather than crescent-shaped.

The following species are known:[1][2]

  • A. glarisianus Agassiz, 1844 (Early Oligocene of Switzerland, Russia, and Germany)
  • A. oblongus Daniltshenko, 1968 (Early Eocene of Turkmenistan)
  • A. solus Bannikov & Erebakan, 2023 (Early Oligocene of North Caucasus, Russia)[2]

The former species A. brevis is no longer considered valid.[2]
