In the present day, turtles do not possess teeth. With the help of ridges on their jaws, they cut off their food. In contrast, their ancestors did not suffer from so many dental problems. In a study led by Dr. Márton Rabi from the Biogeology Lab of the University of Tübingen, scientists have discovered that turtles with remnants of teeth survive 30 million years later than previously believed. In China’s western autonomous region of Xinjiang, researchers discovered evidence of it at a major excavation site. The oldest known toothed turtle found to date dates back 190 million years. In addition, this new discovery contributes to the identification of some of the puzzle pieces in the chelonian family tree, as well as aid in determining how the family was distributed over so BMC Evolutionary Biology published their findings in the most recent issue. It is well known for the dinosaur fossils found at the Xinjiang site of Wucaiwan, which date from the Middle to Late Jurassic period. As well as the fossils of extinct giants, there are also fossils of many other animals that shed light on the long evolutionary history of tortoises and turtles, with more than 350 species living in the wild The team headed by study co-author Dr. Xing Xu of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing identified an extinct turtle species that has a toothed palate, often referred to simply as a turtle. Previous research had suggested turtles still had teeth in their mouths as part of their early evolutionary progress, according to lead author Dr. Walter Joyce of the University of Fribourg. The toothed turtles, however, were determined from rocks 30 million years older than those to which the study referred. Therefore, it is a wonderful surprise to find a toothed turtle that has now survived for

By classifying the new turtle among the known chelonians, as well as learning more about turtle biogeographic history, the researchers were able to learn more about turtle life. During our study of the newly discovered turtle, we discovered that it was an ancient relative of a large turtle called the Mongolochelys efremovi, which lived almost 100 million years later in central Asia. We found that the initial diversification of turtles was primarily controlled by the break-up and disappearance of the supercontinent Pangea during the Jurassic to Cretaceous period,” As a result, each continent developed its own unique turtle fauna, as evidenced by the extinct turtle lineage that was recently discovered in The distribution of fossil and recent turtles and the distribution of continents had not been well recognized as a relationship between terrestrial life and the formation of continents, as was the case with frogs or other amphibians,” asserts coauthor Dr. Clark
