What is "phareodus"

Phareodus is a genus of freshwater fish from the Eocene to the Oligocene of Australia and North America.

This genus includes at least four species, P. testis ( Leidy, 1873) and P. encaustus of North America, P. muelleri of Europe, and P. queenslandicus of Australia. Representatives have been found from the middle Eocene to the Oligocene of Australia and North America, including the Green River Formation in Wyoming, United States.

P. testis was a freshwater fish with an oval outline, a small head, and a slightly pointed snout. Its dorsal and anal fins were situated posteriorly, with the anal fin being larger. Its caudal fin was slightly forked. It had small pelvic fins but long, narrow pectoral fins.
