BEIJING – A new study claims that species dinosaur was on the verge of extinction when a giant asteroid hit Earth and wiped out all the ancient animals.

When dinosaurs went extinct 66 million years ago, the number of animal species dropped dramatically, according to research conducted on dinosaur eggs in China.

As reported by SCMP Friday (23/9/2022), a study by the Chinese Academy of Sciences was also published in the scientific journal, PNAS.

Using dinosaur eggs found in the Shanyang Basin, scientists created a time chronology spanning two million years towards the end of the Cretaceous period, the last period in which dinosaurs lived.

The basin in central China harbors about 1,000 fossil eggs, but upon closer inspection, the researchers found that only three species were actually living at the time.

This means that the diversity of dinosaur species decreased during the Cretaceous period.

“Our results show that dinosaur biodiversity was low during the last two million Cretaceous years. The data suggest a decline in dinosaur biodiversity millions of years before the Cretaceous/Paleogene boundary,” the study authors said.

In addition, scientists also speculate that factors including climate change and volcano eruption The fire may have caused the dinosaur population to plummet.
