Ever wondered what ancient sea monsters looked like? Plesiosaurs, with their long necks and powerful tails, have always sparked curiosity. While scientists have known a lot about their bones for over two centuries, the outer appearance has been a mystery.

Now, researchers dive into an exciting discovery. They have made a detailed look at soft tissue of Plesiosaurs. This isn't just about what they looked like, but it's also about how they lived.

Imagine this: some plesiosaurs had skin similar to ours on their tails and fishy scales on their flippers, much like some sea turtles today. This mix of scales and skin makes their evolution unique. Unlike other ancient sea reptiles such as ichthyosaurs and mosasaurs, which evolved to have skin or smaller scales for better movement, plesiosaurs took a different path.

This discovery is a game-changer. It's not every day you realize that our understanding of something as big as plesiosaurs is missing important details. For nearly 200 years, we've reconstructed them wrong.  It's a big update to their evolutionary history. The findings suggest that plesiosaurs did not adapt in the same way as other ancient sea reptiles.

While these findings shed new light, they also raise questions. How exactly did these features help plesiosaurs survive? What other mysteries are hidden in the fossil record? These questions make us think more about the ancient world these creatures inhabited.
