On September 24, 2021, “Communications Biology” under the Nature Journal reported that a team of scientists from the Institute of Paleospine of the Chinese Academy of Sciences and the Shandong Tianyu Museum of Nature discovered the bones of a 125 million-year-old dinosaur in the Chaoyang area of Western Liaoning, China.
This dinosaur fossil belongs to the oviparous tail feather dragon, named for its special long tail feathers.
The research team extracted a piece of bone near the joint part of the distal femur of Ceratophyllum, after decalcification, and used a series of microscopic imaging techniques to analyze its microstructure, and finally found that the chondrocytes of the dinosaur had undergone silicification after death.
In the next work, the research team extracted some cells and used biochemical methods for staining analysis.
