New marine reptile species discovered in Germany

Paleontologists have uncovered a new ancient marine reptile species from Germany's famous Posidonia Shale.

Discovery of new marine reptile species enriches our understanding of Jurassic ecosystems

In a remarkable find, paleontologists have identified a previously unknown species of ancient marine reptile from the Posidonia Shale fossil beds in Germany. Named Plesionectes longicollum, or "long-necked near-swimmer," this new species offers insight into prehistoric oceans that existed around 183 million years ago. Initially excavated in 1978, the nearly complete skeleton still contains fossilized soft tissue, revealing unique anatomical features that distinguish it from other plesiosaurs. According to Sven Sachs, the lead author of the study, previous examinations had not fully explored this specimen’s anatomy. With the latest research published in PeerJ, the discovery highlights the rich diversity of marine reptiles in the area, confirming the Posidonia Shale as a key site for understanding Jurassic life.

The identification of Plesionectes longicollum marks a significant advancement in the study of marine ecosystems from the Jurassic period. This discovery not only emphasizes the potential for further findings in the Posidonia Shale but also highlights the adaptability and evolutionary pathways of marine reptile species. As the lead researchers note, this extraordinary find helps piece together the environmental changes affecting marine life during a time of drastic oceanic conditions. Such insights can reshape our conception of how ancient ecosystems functioned, offering a clearer picture of biodiversity changes over millions of years.
