Titanonarke is an extinct genus of large electric rays known from the Ypresian age of the Eocene epoch. It currently contains two species from the Bolca Lagerstatte of Italy, T. molini and T. megapterygia. The exceptional preservation of multiple entire individuals has allowed a detailed reconstruction of their lives.

This species seems to prefer shallow water habitats associated with coral reefs, not u
