People Have Been Dining on Caviar Since the Stone Age

Millennia before caviar became a staple hors d'oeuvre at posh parties, it was eaten from clay pots by Stone Age humans. That's the takeaway of a new study published in the journal PLOS One. As Smithsonian reports, traces of cooked fish roe recovered from an archeological site in Germany show just how far back the history of the dish goes.

For the study, researchers from Germany conducted a protein analysis of charred food remains caked to the shards of an Stone Age clay cooking vessel. After isolating roughly 300 proteins and comparing them to that of boiled fresh fish roe and tissue, they were able to the identify the food scraps as carp roe, or eggs. The scientists write that the 4000 BCE-era hunter-gatherers likely cooked the fish roe in a pot of water or fish broth heated by embers, and covered the pot with leaves to contain the heat or add additional flavor.

The clay shards were recovered from Friesack 4 in Brandenburg, Germany, a Stone Age archaeological site that has revealed about 150,000 artifacts, including items crafted from antlers, wood, and bone, since it was discovered in the 1930s. In the same study, the researchers report that they also found remnants of bone-in pork on a vessel recovered from the same site.

Other archaeological digs have shown that some of the foods we think of as modern delicacies have been around for thousands of years, including cheese, salad dressing, and bone broth. The same goes for beverages: Recently a 13,000-year-old brewery was uncovered in the Middle East.

If you’ve never visited the Big Bone Room, you’re in luck. Check out our visit to New York City's American Museum of Natural History for a rundown on fossils, which provide invaluable insight into our understanding of history and its once-living occupants.

In this edition of "The List Show," editor-in-chief Erin McCarthy explains the ins and outs of excavation, fossil follies (extinct giants were a big miss), and the terrorizing prospect of a 3-foot-tall parrot.

2000-Year-Old Roman Tweezers and Metal Ear Swab Discovered in UK

The ancient Romans took hygiene seriously. They pioneered indoor plumbing, deodorant, and the practice of bathing daily. A recent discovery made at a bridge construction site in the UK reinforces just how committed to cleanliness the Roman civilization was. As Geek.com reports, workers unearthed an ear cleaner and a pair of tweezers thought to date back 2000 years to the Roman Empire.

The artifacts were dug up by the Ebbsfleet Development Corporation at the location of the new Springhead Bridge in Ebbsfleet Garden City, a development in Kent. One small tool appears to be designed for pinching and plucking small items just like modern-day tweezers. The other object is thought to have been built for cleaning ears—but instead of cotton, the "swab" is made entirely of metal. They're thought to date back thousands of years, but scientific analysis will need to be done to determine the exact age.

Grooming items weren't the only artifacts uncovered at the site. Workers also found a piece of timber believed to have been meant for an ancient structure. The Ebbsfleet River, where the new bridge is being built, was once a shipping hub and a Roman settlement called Vagniacis. Historical finds are so common in the area that the Ebbsfleet Development Corporation employs full-time archaeologists.

The personal hygiene tools have been removed from the archaeological site by experts who will study them to learn more about their origins. The fate of the artifacts is unclear, but the construction company behind the discovery hopes they can remain in the same city where they were found.
