Culinary Paleontology: World's Oldest Tomatillo Fossil Found in Ypresian Eocene Paleogene Argentina

A fossilized tomatillo, still in its papery shell, is the earliest fruit from the tomato family ever found in South America, researchers reported Oct. 30 at the Geological Society of America's annual meeting in Denver.

The 52.2-million-year-old tomatillo was discovered at the fossil-rich Laguna del Hunco, Argentina, where ancient lakebeds interlayer with volcanic ashes, providing paleontologists with precisely dated discoveries. (Minerals in the ash pin down the rock ages.)
