Sphenonectris turnerae [1]

Sphenonectris is an extinct genus of furcacaudiform thelodont which lived in the Northwest Territories of Canada during the Early Devonian period. It hails from the MOTH locality in the Mackenzie Mountains.[2]

Though large by furcacaudiform standards, Sphenonectris were small, jawless fish, characterized by their laterally compressed pot-bellied body and forked tail. They possessed a hunched pomacanthid-like body with the only visible fin being the caudal fin.[2]
