The soft tissue of a plesiosaurus has first been examined, the maritime reptiles that lived during the dinosaurs, and were similarly similar to the modern sea turtles that disappeared.
The 450-year-old, 183 million year old known as MH7, was excavated from the 1940s of Holzmad quarry, but was buried in a museum garden to protect it during World War II. Then, in the next 75 years or the warehouse passed in 2020 until they finally gathered and prepared.
Miguel Marx They prepared the thin sections of the Swedish University and his team, then they were treated, so the minerals were dissolved, leaving organic remains. This allowed the opportunity to study the microscopic structure of fossil fabric.

Although the other eight plesiosaur fossils are preserved by soft tissue, most are historically significant museum copies and cannot learn to use devastating sampling methods, according to Marx. “It’s the first time anyone has done a deep study of soft fossilized tissue of a plesiosaurus,” he said.
The group was surprised to discover that the reptile had a smooth and scaled skin. “Taken together, this plesiosaur was an interesting chimera with something similar to a green sea school, scale and (smooth skin) turtle,” says Marx. “I would expect this plesioosose to have less scale like contemporary Ichtious ichtiousos.”
Flippers scaled skin probably helped giving the plenas in the mood, accompanied by a rigidity or when he went in search of food, he said. The rest of the body’s less skin skin would reduce the effects of dragging when swimming.
“It’s really the external look of the long neck pleadingness, but now we have a better idea thanks to this new fossil,” says Marx.
