This 52 million-year-old fossil is the world’s oldest tomato

Now this is an heirloom tomato.

Scientists searching a prehistoric lake bed in southern Argentina recently uncovered the fossilized remains of a tomato that dates back 52.2 million years.

The discovery of the ancient edible shows that tomatoes have existed some 30 million years longer than researchers previously had thought.

The sample — which was found in an area known as Laguna del Hunco in an area called Chubut, according to the Mirror — is actually thought to be so old that it is likely the ancestor to the potato, the cucumber and even tobacco.

The tomato is similar to the Mexican husk tomato, and it wound up being preserved for eons after it fell into a lake next to a volcano.

The water had very little oxygen in it, and that helped the fossilization process, the Mirror reported.
