Scientists have identified a remarkably preserved fossil in China that is shedding new light on a long-necked marine reptile that lived about 245 million years ago. The find stands out because it preserves evidence of the animal’s internal organs, something rarely seen in fossils of prehistoric reptiles.
The marine reptile lived during the Triassic period, a crucial era in the recovery and diversification of life after Earth’s largest mass extinction. Discoveries from this time can help researchers better understand how marine reptiles evolved and adapted to life in ancient seas.
What makes this China fossil especially important is the unusual level of preservation. Fossils often preserve bones and hard structures, but soft tissues and internal anatomy are far less likely to survive over millions of years. That makes this specimen a valuable source of information about how the animal’s body was built and how it may have functioned.
Researchers say the fossil offers a rare window into the biology of an early marine reptile, not just its skeleton. By revealing internal organs along with the animal’s long-necked form, the specimen adds to a growing picture of prehistoric ocean life and the exceptional fossil record found in China.
