Scientists have confirmed that a group of fossilized tracts found in northwest China were left by flesh -eating dinosaurs over 120 million years.
years ago, providing insights into the social behaviors of these ancient creatures.
The track site is located in Wulan Town, in Gansu Province.
Scientists discovered at least 67 three -toed tracks on a cliff.
The lengths of these tracks range from 11 centimeters to 21 centimeters, and none include the first toe or tail marks.
Considering the lengths and shapes of the tracks scientists estimated that the creatures had a hip height between 60 and 90 centimeters with the largest one having a body length of up to 2 .5 meters while these creatures moved in a nearly straight line.
After a detailed examination, scientists identified these tracks were made by a kind of carnivorous dinosaur that roamed the earth during the Cretaceous period.
The study results have been published in the International journal Historical Biology.
The track site is situated about 100 kilometers east of the lower Cretaceous -Hukou group, an area renowned for having one of the highest diversity of Cretaceous four -footed tracks in China.
According to the lead author, Xin Lidas, previous studies have shown that some groups of small biped dinosaurs had demonstrated gregarious behavior.
In the new study, scientists discovered 12 similar -sized tracks.
Some of them run parallel to each other, moving in the same direction, which indicates that these species might have exhibited social behavior.
Xin Lida, also Associate Professor at the China University of Geosciences Beijing, noted that such behavior could have been a strategy for small dinosaurs to protect themselves from predators.
These well -preserved footprints offer new scientific evidence concerning the distribution of dinosaurs in China, and provide clues that can help scholars gain a deeper understanding of dinosaur footprints and behaviors.

A new study has highlighted the ecological effects of tiny plastic particles on food webs in terrestrial ecosystems, shedding light on how plastic waste compounds the ongoing environmental crises.
The study published in the journal Trends in Plant Science was jointly conducted by researchers from Xi Shuang Ba Na Tropical Botanical Garden under the Chinese Academy of Sciences, King Abdullah University of Science and technology in Saudi Arabia and University of Southern Denmark.
Micro and nanoplastics refer to plastic particles and fibers ranging from one nanometer to five millimeters in size which pose an emerging threat to both marine and and terrestrial ecosystems.
The researchers found that such tiny plastics accumulate in most studied plants and associated above ground and below ground biota.
These particles can transfer along food webs, potentially disrupting ecosystem functionality.
Xiu Guo Re, a researcher at the Xizhuang Ban Na Institute, said that these tiny plastics, once absorbed by plants interact with herbivores, pollinators, and mycorrhiza.
The study also proposed ketropic and non -tropic transfer pathways of the micro and nanoplastics along the food webs, which could potentially impact biodiversity and ecosystem multifunctionality.
Furthermore, the researchers emphasized the urgent need for further studies on terrestrial ecosystems to comprehensively assess the ecological impacts of tiny plastic waste and to formulate strategies to mitigate their effects on plants and their interconnected food webs.

It's the looking forward to the Spring Festival or the Chinese Lunar New Year to celebrate the most important traditional holiday.
The Chinese government allows working people to have 8 days off with a change of workshift.
For the workers in China today, non -work days account for about one third of each year.
Apart from weekends and the annual leave, people also stay away from work on several traditional holidays.
holidays, how did such a holiday system come into being and how about people in ancient China?
How did they organize their days off from work?
In ancient China, the vacation for average farmers who accounted for the overwhelming majority of the population was very simple.
They could take a break whenever they wanted during the non -farming period.
As for government officials, the holiday system dates back to 2 ,000 years ago when the Han Dynasty issued the Han law.
At that time the regular leave of government officials was called shionmu, with mu meaning taking a bath.
This vacation literally means just go home to take a bath and take a break.
Starting from the Western Han dynasty in around the third century BC, officials took one bath day off in every five days.
So why was it called a vacation for taking a bath.
Firstly, all public officials lived in their office at the time.
When they took one day off, they could go home and take a bath, and more importantly, spend time with their family.
Secondly, taking a bath meant more than just cleaning one's physical body.
In the ancient Chinese culture, it also meant cultivating and enriching the official's inner spirit.
Taking a bath day off was a good description as ancient Chinese society placed a very high ethical and and moral standard on government officials.
Back then, the Bath Day was the most basic, regular vacation.
This mechanism was inherited by many dynasties after the Western Han.
By the Wei, Jin and Southern and Northern dynasties centuries, between the third and the sixth century, the holiday system became more humane.
There were several private sacrifice holidays each year, each for four days when officials Officials could go home to pay tribute to the deceased relatives and friends.
Officials could also have a nine -day marriage leave, and up to sixty days of tomb -sweeping leave.
These are a reflection of how much value the Chinese placed on family, filial piety and ancestral worship.
By the time of the Tang dynasty, which began in the 7th century, vacation systems had become pretty well fixed on the basis of the system which held sway during the previous dynasties.
The Tang government included various traditional festivals such as the Spring festival, the Cold Food festival, the mid Autumn Festival, the beginning of Spring, the Summer Solstice and the Winter Solstice.
The Tang government attached great importance to the Winter Solstice and the Spring Festival, so officials could take seven days off during these two holidays, the equivalent of the two so -called golden weeks today.
Because more traditional holidays were included into the holiday system, Tang officials overall enjoyed much longer vacations than those during the Han Dynasty.
In the mid -ninth century, Emperor Emperor Wu Zong of the Tang Dynasty once ordered construction workers to continue working during the Cold Food Festival.
The workers were upset and they staged a protest.
As a result, the emperor had to reward each worker with some silk and gave them three days off in order to dispel their anger.
The story bears a striking resemblance to the labor movement in British history, where workers took to the streets to demand an eight -hour workday.
It also shows us that the need to take a break from work is universal.
In the late Qing dynasty, under Western influence, the government designated Sunday as the day off, thereby gradually establishing a holiday system in line with Western practice.
From a historical perspective, the golden weeks and weekends in China today represent a combination of Chinese and foreign wisdom.
In every culture, holidays are usually closely related to the way of life of the people, traditions, and customs.
It's fair to say that understanding a country's festivals and vacation system is an excellent window to understand its culture.
