It's even older than that thing in the back of my fridge. LiveScience:
After more than 120,000 years trapped beneath a block of ice in Greenland, a tiny microbe has awoken. The long-lasting bacteria may hold clues to what life forms might exist on other planets.
The new bacteria species was found nearly 2 miles (3 km) beneath a Greenland glacier, where temperatures can dip well below freezing, pressure soars, and food and oxygen are scarce.
"We don't know what state they were in," said study team member Jean Brenchley of Pennsylvania State University. "They could've been dormant, or they could've been slowly metabolizing, but we don't know for sure."
Dormant would mean the bacteria were in a spore-like state in which there's not a lot of metabolism going on, so the bacteria wouldn't be reproducing much. It's possible the bacteria could have been slowly metabolizing and replicating.
