Scientists have found new fossil evidence confirming that turtles have lived without shellfish for some time.
The fossil, which is found almost entirely, belongs to 228 million years ago and is larger than a double bed. The fossil was discovered in the Guizhou province of southwest China
The director of natural sciences from the National Museum in Edinburgh, Scotland. Nicholas Fraser says, “He looked like a turtle, but he did not have everything under his shell and at the same time.”
“There is a skeleton for the shell to exist, but it does not have the shell. There is a very characteristic beak at the front end. “
This ancient reptile was named Eorhynchochelys sinensis. This name means “a beak from China and the backbone of a turtle.”
Why is the tortoise’s crust important?
The crust is there to help protect the tortoises, but at the same time it can help keep the tortoise under water longer. That’s why the storage of potassium and magnesium can help protect the shell from lactic acid buildup.
The tortoise shell consists of about 50 bones with ribs, shoulder bone, and spine fused together to form a hard outer layer.
“Turtles are very strange animals. They have a crazy shirt with a crust. If you can imagine your shoulders in your rib cage, you will find that you have a very limited ability to move. “
“Extremely exotic animals have survived for more than 200 million years.”
How did the tortoise’s crust come about?
How the turtle shell evolved has been fooling scientists’ heads for years.
From the fossil record, some primitive turtles with a whole shell were already known. The earliest tortoise fossil before this discovery, a little animal called Odontochelys, had a fully formed skin on its lower surface, but there was no bony cover at the top of the body.
Researchers say that with the new discovery, we are closer to understanding how the shells of the tortoises develop.
“We see in this animal that the ribs have begun to expand. We are waiting for the next fossil to see what happens. “
