Marcopoloichthys is an extinctgenus of marine teleosteomorphray-finned fish known from the Middle and Late Triassic of the former Tethys Ocean (Italy, Switzerland, and China). It is the only genus in the family Marcopoloichthyidae. It was originally described based on specimens from both Italy and China, hence the name Marcopoloichthys, which references the medieval Venetian merchant Marco Polo, who travelled from Italy to China.[1][2]
M. furreri Arratia, 2022 – Ladinian of Grisons, Switzerland
The youngest Marcopoloichthys fossils are of an undescribed species from the Norian of Friuli, Italy.[3]

Marcopoloichthys was a small, scaleless fish with highly specialized, protractile jaws for suction feeding, and a combination of primitive and advanced morphological characters that make it difficult to phylogenetically place. Initially described as an indeterminate basalneopterygian, more recent studies have found it to be a stem-teleost. It somewhat resembles another early teleostomorph, Prohalecites.[1][3]
