What was the speed of the Muraenosaurus?

The Muraenosaurus, a genus of marine reptile from the Late Jurassic and Early Cretaceous periods, is estimated to have been capable of swimming at speeds of around 4 to 5 kilometers per hour (2.5 to 3.1 miles per hour). This relatively moderate speed was likely sufficient for hunting fish and navigating its aquatic environment. However, specific speed estimates can vary due to the limitations of fossil evidence and the assumptions made in biomechanical studies.
