Pharyngolepis is an extinct genus of primitive jawless fish that lived in the Silurian period.
Lacking stabilizing fins, it is thought to have been a poor swimmer. Pharyngolepis did have a well-developed caudal fin. Around its chest region it had some spikes, possibly for protection against predators. Scientists presume it scooped up food from the ocean floor.
