Trewavasia carinata is an extinct pycnodontid that lived during the lower Cenomanian of what is now Lebanon.[1] It had a large, forward-pointing horn-like spine between its eyes, and a massive stump-like spine emanating from the back of its head. T. carinata is closely related to the very similar looking genera Ichthyoceros and Hensodon, as well as Coccodus.
