Myledaphus is a genus of Late Cretaceous cartilaginous fish whose fossils are known from Canada, the Midwest of the United States, and Uzbekistan. It was a freshwater guitarfish that probably reached a length of 3 feet long, and had teeth adapted for a durophagous diet of animals such as clams.
The most common remains of this fish are teeth and vertebra. A study performed on Myledaphus vertebra from Alberta in 2013 revealed that Myledaphus had an estimated maximum age of 16 years. This means that Myledaphus had a shorter lifespan than that of the modern common guitarfish, by a difference of 8 years.
