☆ New tests confirm antiquity of ancient human footprints in New Mexico

A 2021 study by these researchers also dated the footprints, based on tiny plant seeds embedded in the sediment alongside them, to about 21,000 to 23,000 years ago. This paper is that corroborative exercise," added study co-lead author Kathleen Springer, also a USGS research geologist in Denver. Scientists believe our species entered North America from Asia by trekking across a land bridge that once connected Siberia to Alaska. The researchers also used optically stimulated luminescence dating to determine the age of quartz grains within the footprint-bearing sediments. "And just like today, if anyone walks in a similar setting, their footprints are preserved if they are covered with another layer of sediment," Springer added.

Xinhua/Shutterstock‘Absolutely safe’As heavy rains moved toward the region in late July, China’s top flood control officials met to hash out their response plan. The flood was caused by flood water discharge, not by heavy rainfall.”CNN has reached out to the Zhuozhou and Bazhou governments for comment. Rescuers use rubber boats to transfer Zhuozhou residents trapped by flood waters after days of downpours brought by Typhoon Doksuri on August 2. In the recent rains, at least three upstream reservoirs released flood waters into rivers flowing into Baiyingdian from the west and the south, according to state media. Many countries have systems that involve discharging pent up flood waters into otherwise dry land after major storms.
