The analyzed amber fragments allow direct insights into environmental conditions that prevailed in West Antarctica 90 million years ago, indicating an ancient temperate rainforest.
This fascinating find also indicates in more detail how the forest we reconstructed in our Nature study from 2020 could have functioned.
So far, amber deposits have been described from every continent except Antarctica, marking this as a significant paleobotanical discovery.
At some point in their history, all seven continents had climatic conditions allowing resin-producing trees to survive, highlighting a vastly different Earth.
