Boreosomus gillioti is an extinct species of Triassic ray-finned fish.[2]

Fossil record[edit]

This species is known in the fossil record from the Early Triassic (from about 252,3 to 251,3 million years ago). Fossils of this quite rare species have been found in Madagascar.[3]

Description[edit]

Boreosomus gillioti could reach a body length of about 10–20 cm (3.9–7.9 in). These small to medium sized extinct fishes had a slender body and a small dorsal fin located before the body's midpoint. Caudal fin were divided. Scales were strong and rectangular.[4]
