Scientists discover China's largest dinosaur track site

An international research team announced on Thursday that it has discovered a site of more than 900 fossilized dinosaur tracks, covering an area of 9,000 square meters, the largest of its kind ever found in China.Paleontologists find footprints of hadrosaur at the Zhaojue dinosaur footprint cluster. (Photo: Courtesy of Xing Lida)The dinosaur track site was located in a copper mine in Zhaojue County, southwest Chinas Sichuan Province.From 2017 to 2019, paleontologists from China, the United States and Germany through fieldwork or using drone technology recognized at least 933 dinosaur tracks dating back 100 million years at the site, including Chinas longest recorded sauropod and ornithopod trackways, which are 80 meters long and 52 meters long, respectively.Scientists believe these tracks were left by 68 trackmakers. Parallel tracks left by ornithopods were also found in the site, indicating that the dinosaurs, which were previously thought to be solitary, lived in groups.Scientists have also found three smaller but important sites of dinosaur tracks nearby since the 1990s, bringing the number of recognizable tracks found in the county to 1,928.The findings were published in the international journal Geoscience Frontiers in late February."Such a diverse set of dinosaur tracks is an excellent sample for studying Cretaceous dinosaur fauna in this area," said Xing Lida, lead author of the article and researcher at China University of Geosciences.Xing also noted that mining operations had prompted the discovery of new records but also caused some damage to the sites. His team once tried to document the bits that remained after local mining companies broke up a site."The Zhaojue sites provide a good example of dinosaur track sites that require long-term study and monitoring to extract as much data as possible before evidence is lost," Xing said.In the study, scientists called for more government efforts to preserve the sites, as the dinosaur...

Chinese researchers conduct satellite tracking of wild snow leopards

Photos: Chinanews.comLANZHOU, March 4 (Xinhua) -- A research team in northwest Chinas Gansu Province has successfully tracked a wild snow leopard by satellite for nearly a month, local authorities said.After being approved by the National Forestry and Grassland Administration, the management bureau of Gansus Yanchiwan National Nature Reserve, together with the Beijing Zoo, Wild World Jinan and other institutions, launched the satellite tracking in December 2020.The tracking is meant to strengthen the monitoring and research of the behavior and habitat of snow leopards and promote the formulation and implementation of protection plans for the endangered species, said Wu Liji with the management bureau.In early February, researchers caught a wild female snow leopard in the reserve and attached a positioning collar around its neck before releasing it back into the wild."Nearly a month of tracking has shown that the snow leopard is still in the vicinity of the field, and the collar and the animals vital signs remain normal," said Wu.The research team will further analyze the satellite data to fully understand the movements and habitat selection of snow leopards in the Yanchiwan reserve.The snow leopard is a Class A protected animal in China and is classified as "vulnerable" by the International Union for Conservation of Nature. It is estimated that about 2,000 live in Chinas Qinghai, Xinjiang, Tibet, Sichuan and Gansu.

SpaceX rocket explodes on ground after seemingly successful flight

An unmanned SpaceX rocket exploded on the ground Wednesday after carrying out what had seemed to be a successful flight and landing.This screengrab made from SpaceXs live webcast shows the Starship SN10 prototype during the second attmpted test flight of the day at SpaceXs South Texas test facility near Boca Chica Village in Brownsville, Texas, March 3, 2021. (Photo: AFP)It was the third straight flub involving the prototype of the Starship rocket, which SpaceX hopes one day to send to Mars. The last two test flights ended in crashes."A beautiful soft landing," a SpaceX commentator said on the live broadcast of the test flight, although flames were coming out at the bottom and crews were trying to put them out. The rocket exploded a few minutes later. It was thrown into the air and crashed back to the ground.No explanation was immediately provided.As seen on SpaceX video, the rocket appeared to have otherwise landed properly after its flight.SpaceX founder Elon Musk has been developing the next-generation Starship rocket for the purpose of going to Mars -- though two prototypes blew up in spectacular fashion on their recent test runs. The latest prototype, named SN10, for "serial number 10," took off a little before 1120 GMT from Boca Chica, Texas.The two other prototypes (SN8 and SN9) crashed on landing, in December and then in early February.The tests take place in a nearly deserted area leased by SpaceX in South Texas near the border with Mexico and next to the Gulf of Mexico -- the area is vast and empty enough that an accident or explosion would not cause damage or fatalities.Apart from Mars, the rocket, if it becomes operational, could also prove useful for closer trips, especially to the Moon.
