The Oldest Stuff on (and Off) Earth!

Posidonia Oceanic

The Mediterranean Sea has borne witness to a lot of drama over the last 100,000 years, and Posidonia oceanic has had a front row seat to all of it. In 2012, a group of Australian scientists sequenced the genes of this seagrass species and found that it was at least 100,000-years-old, and possibly as old as 200,000! This makes the humble aqua-turf by far the oldest living thing on Earth.
