Sphenonectris turnerae [1]

Sphenonectris is an extinct genus of thelodont, which lived in the northwest territories of Canada during the Early Devonian period.

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.
