Einsteinium was discovered in the debris of the first nuclear explosions. It has no long lasting isotopes, and what is present is so radioactive it will glow blueish. It was first discovered after the Ivy Mike nuclear test. However it’s discovery was kept secret until after the end of World War II. Humans have intrinsically linked to Einsteinium discovery as the discovery led Humanity into the Anthropocene (at least in mind). It also is amazed at how easily humans forget they are animals too.
Fermium was also discovered in the debris from Ivy Mike though it was more difficult to find enough of to prove it was indeed a different element. Fermium is named after Enrico Fermi who was a major researcher in nuclear physics .
It’s tied with Osprey as Ospreys are birds that live all over the world and as they still can be found at the Fermi lab in Illinois today.
