Sclerorhynchus is an extinct genus of primitive skate that lived in the Cretaceous.

Despite being a skate, it looked more like a sawfish, having a long snouth with tooth-like serrations lining the sides. Physically it looked like a somewhat flattened shark with enlarged, wing-like pectoral fins. It probably used these to glide over the ocean floor, propelled by its tail, weeding out shrimps, shellfish and flounders from the sand with its long snout.
