A tiny ancient squirrel essentially functioned as a living, walking environmental sensor for its entire ecosystem.The preservation power of permafrost never ceases to amaze me. To get viable, multi-species DNA reads out of ancient droppings like this is incredible sequencing work**

There’s a Monty Python skit in here somewhere.

Rodents today love gnawing on bones for the calcium. I wonder if bone chewing was the reason for these ancient DNA findings too?
