    Essential Insights

    1. A newly analyzed plesiosaur fossil reveals it had flipper scales akin to modern sea turtles, which may have aided in swimming or substrate navigation, highlighting the evolution of marine adaptations around 183 million years ago.

    2. The complete and well-preserved fossil, excavated in Germany, shows unique features such as smooth skin on the body and scaled flippers, suggesting a specialized evolutionary response to aquatic life.

    3. Plesiosaurs, believed to be warm-blooded and live bearers, exhibited anatomical traits that likely provided advantages for benthic feeding and movement, supporting their role as successful marine predators during the Jurassic.

    4. This study emphasizes the retention of reptilian scales in plesiosaurs, contrasting with other marine reptiles that lost their scales, and underscores the significance of these adaptations in their prolonged evolutionary success.

    Amazing Fossil Reveals Turtle-Like Scales on Jurassic Plesiosaur

    A new fossil discovery has transformed our understanding of plesiosaurs, the serpent-necked marine reptiles from the Jurassic period. Researchers, led by Miguel Marx from Lund University, have found that these ancient predators sported flipper scales reminiscent of today’s sea turtles.

    This remarkable fossil, labeled MH 7, measures about 4.5 meters long and dates back 183 million years. Excavated in Germany in 1940, it has undergone extensive analysis using sophisticated microscopy and spectroscopy techniques. Furthermore, the preservation of soft tissues in this fossil is exceptional, making it a rare find in the paleontological community.

    Marx and his team noted that the skin on MH 7’s flippers featured small, irregular scales. In contrast, the tail maintained smooth skin. The scales likely assisted in swimming efficiency or provided traction on the ocean floor. Such traits indicate that plesiosaurs may have been adapted for diverse environments, enjoying both aquatic freedom and adaptability to the seafloor.

    Plesiosaurs were born live and breathed air, which hints at possible warm-bloodedness. During their time, they flourished as top marine predators. The latest findings suggest that these reptiles retained their scales after evolving from land-dwelling ancestors, likely gaining evolutionary advantages over their contemporaries, such as ichthyosaurs, which lost their scales to minimize water resistance.

    The implications of this research extend beyond paleontology. Understanding how prehistoric creatures adapted their bodies may inform technology development today. For instance, examining the hydrodynamics of these scales could inspire new designs for underwater vehicles or robotics, enhancing efficiency and functionality in aquatic environments.

    Overall, this study contributes to the growing body of knowledge about the evolutionary paths of marine reptiles. The unique characteristics of MH 7 highlight the adaptability and complexity of life during the Jurassic era, promising exciting revelations in future research. The team’s findings are published in the journal Current Biology.
