Brycon dentex (Müller and Troschel 1844; 80cm) is the extant South American trout or Sabalo barracuda. Here it nests close to Salmo, the salmon (a type of trout) This omnivore eats fruit and seeds that fall into the water, along with small fish and invertebrates. The naris entrance is confluent with the exit. The teeth are robust and continue down the maxilla.

Cooyoo australis (Lees and Bartholomai 1987, Early Cretaceous) is a long, slender icthyodectid with a large tail, related to Brycon in the LRT.

Hiodon alosoides (Lesueur 1818; 45cm in length) is the extant mooneye, a freshwater fish from eastern North America. It nests basal to mormyrids in the LRT. This species looks more like the more primitive Brycon.

Hiodon tergisus (Lesueur 1818; 45cm in length) is the extant mooneye, a freshwater fish from eastern North America. It nests basal to mormyrids in the LRT.

Phareodus encaustus (Cope 1871; Leidy 1873; Li, Grande and Wilson 1997; Paleocene to Eocene, 65–46mya) from North America, Europe and Australia nests with Hiodon tergisus. Long narrow pectoral fins and small pelvic fins are present on this discoidal fish with a large upper temporal fenestra. The palatine rims the orbit.
