Dinocephalosaurus orientalis, a fascinating marine reptile first identified in 2003, has been fully described for the first time thanks to newly uncovered fossils from southwestern China.
The discovery, detailed in the journal Earth and Environmental Science Transactions of the Royal Society of Edinburgh, was made by an international team of scientists from China, the United States, and Europe, including Dr. Stephan Spiekman of the State Museum of Natural History in Stuttgart.
This long-necked reptile bears a resemblance to the mythical Chinese dragon, with its elongated form and snake-like appearance. Unlike plesiosaurs, which evolved nearly 40 million years later and inspired legends like the Loch Ness Monster, the Dinocephalosaurus was a distinct species with an extraordinary anatomical structure.
It had 32 cervical vertebrae, far more than its relative, Tanystropheus hydroides, a Middle Triassic reptile found in both Europe and China.
The world’s oldest long-necked marine reptile
Dinocephalosaurus was not just unique in shape—it also gave birth to live young, a rare trait for reptiles, making it well-suited for life in the sea. Fossil evidence suggests it was highly adapted to its marine environment, with fin-like limbs and preserved fish remains in its stomach, indicating a diet of ocean prey.
This discovery gives paleontologists the first look at Dinocephalosaurus orientalis, helping them better understand the evolution of marine reptiles in the Triassic period. This remarkable species will surely capture imaginations worldwide with its dragon-like appearance and oceanic adaptations.
Dr. Li Chun, author of the study and curator at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, said, “This was an international effort. Collaborating with colleagues from the United States and Europe, we utilized newly discovered specimens to expand our previous knowledge of Dinocephalosaurus. This marine reptile probably stands out as the most remarkable among all the extraordinary Triassic finds we have made in Guizhou Province.”
