Mandelbaum at Gizmodo. Dussex and his colleagues describe their findings in a paper published this month in the journal Communications Biology.

A group of fossil ivory hunters, who are legally permitted to excavate tunnels near the village of Belaya Gora in northeastern Siberia, found the frozen bird trapped several feet underground. In 2018, they contacted study author Jacquelyn Gill, a climate scientist at the University of Maine who had previously been involved in permafrost discoveries in the area.
