Tooth turtles can last more than 100 million years ago
A new archaeological finding suggests that tortoises can last more than 100 million years ago a few dozen million years more than what was previously identified.
A new archaeological finding suggests that the turtles can survive more than 100 million years ago compared to a few tens of millions of years ago what was previously identified.
Accordingly, a group of international researchers, including Dr. Marton Rabi from the Lab Biogeology Institute of Tübingen University, discovered the fossil remains of an estimated tortoise of about 190 million years old.
This is considered a new finding confirming that the ancient toothed turtle appeared earlier than we thought instead of the tens of millions of years previously identified. At the same time, this archaeological discovery continues to provide newer information, to reinforce the biological system of the chelonian turtle family millions of years ago.
The incident was discovered in a Jurassic Wucaiwan land, in the Xinjiang Autonomous Region, China. And this finding has just been published in BMC Evolutionary Biology.
Earlier, Dr. Walter Joyce from the University of Friborg, Switzerland found the fossil stone of a 30 million-year-old toothed turtle , named Sichuanchelys palatodentata, a turtle with teeth on the palate , estimated to be tortoise This inherited evolution from previous reptile ancestors. Now, however, this 30-million-year-old toothed turtle is no longer the oldest toothed turtle in the world.
According to the analysis, the 190 million-year-old ancient toothed turtle has found a close biological relationship with the terrestrial giant tortoise named Mongolochelys efremovi who lived in Central Asia 100 million years ago. And these two lines of turtles began to evolve evolutionarily, starting in the Trung Sinh period.
' Although turtles are not as highly dispersive as other animals, however, recent findings suggest that ancient turtles have evolved evolutionary quite clearly, classified by different regions ".
" The cause may be due to the impact of the breakage, fracture of tectonic plates after the Cretaceous period , so each continent has a distinctive turtle species, as well as archaeological turtles archaeological sites. Currently in different continents, different species and time appear . " - Dr. Joyce said in a statement.
