How fast did a elasmosaurus swim?

Answer 1

Elasmosaurus, a genus of plesiosaur, is estimated to have had a cruising speed of around 1 to 2 kilometers per hour (0.6 to 1.2 miles per hour). This relatively slow speed is thought to be due to its long neck and large body, which made rapid movement challenging. However, it could have reached short bursts of speed when necessary, especially for hunting or evading predators. Overall, elasmosaurus was likely adapted for a more leisurely swimming style in its marine environment.
