Thrissops formosus, a member of the family Ichthyodectidae (literally "fish-biters"), was a swift-swimming predatory fish with streamlined body and deeply clefted caudal fin from the Lithographic Limestone deposits around Solnhofen, Germany. Dorsal and anal fins are broad based and attached behind the body's midpoint. The anal fin is diagonally attached slightly before the dorsal fin.
