In a first, enamel proteins 18-20 million years old from tropical, High Arctic sites unravel palaeobiology of extinct taxa
If obtaining sequences from ancient proteins found in fossils was previously limited to samples no older than four million years, two studies published in the journal Nature on Wednesday (July 9, 2025) have pushed back this timescale to more than 20 million years. The enamel proteins from extinct mammals are a staggering ten-fold older compared with the … Read more
