Abstract in brief

Scientists uncovered a 2-million-year-old ecosystem in Greenland, revealing a climate that closely resembles future warming predictions, with temperatures significantly higher than today.
The analysis of ancient environmental DNA (eDNA) from the Kap Kopenhagen Formation showed an open boreal forest with a diverse range of mixed tree species and numerous shrubs and herbs that were previously unrecorded at the site.
The findings included evidence of ancient animals like mastodons, reindeer, and various marine species, highlighting a unique ecosystem that has no modern equivalent and suggesting new avenues for genetic research into prehistoric biological communities.
