Nuclear technology helps scientists study Australia's prehistoric ecosystems
Washington (UPI) Dec 11, 2017
With the help of nuclear technology, scientists in Australia have begun to unlock the secrets of prehistoric fossilized tree resin - time capsules made of amber. Researchers at Monash University used magnetic resonance to analyze several amber fossils, dated between 52 and 40 million years old. The golden-hued nuggets can offer insights into the continent's prehistoric ecosystems. Amber, or fossilized resin, is the sap of seed plants, hardened over millions of years. "Our collabo ... read more
