Chinese scientists have found that Lufengosaurus, the herbivorous dinosaurs of the Jurassic period, were not cold-blooded at all.
Studies of recently discovered fossils of two individuals of this species helped determine the metabolic rate of ancient animals and draw a number of scientific conclusions.

Zhao Qi, Junior Researcher, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences. - However, their metabolic rate is also not as high, but much higher than that of some ordinary reptiles. Therefore, in a broader sense, Lufengosaurs can be considered warm-blooded animals.
In addition, paleontologists are able to determine the exact age of dinosaurs from a thin sample taken from the remains found.
“We can see that there are lines that look like annual tree rings. In some reptiles, growth occurs in cycles, and such lines form in them. By counting the number of lines, we can find out its age. For example, now we can say with confidence that this dinosaur was 3 years old,” says Zhao Qi.
Lufengosaurus is a genus of dinosaur discovered in 1938 in Lufeng County in Yunnan Province in China. Later, more than a hundred complete skeletons of ancient animals belonging to different stages of the Jurassic period were found in this place. The remains of two new individuals were discovered this year by local residents: after heavy rains, the fossils were washed out of the soil. The first contemporary of the early Jurassic period has already been sent for restoration to the Dinosaur Museum, and paleontologists are still looking for parts of the second skeleton. At the same time, near the excavation site, scientists found traces of Lufengosaurus.
“A rare case of finding footprints next to dinosaur fossils. Based on the footprints found, we can draw conclusions about the behavior of Lufengosaurus, whether it lived in groups and whether it ran fast,” said Sin Lida, an assistant professor at the China University of Geosciences.
and other types of ancient animals, including feathered dinosaurs and ancient birds - a total of 190 species.
