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.

Mastodon Bones Have Been Discovered by Sewer Workers in Indiana

When something unexpected happens during a sewer system project, the news is not usually pleasant. But when workers installing pipes in Seymour, Indiana stopped due to an unforeseen occurrence, it was because they had inadvertently dug up a few pieces of history: mastodon bones.

According to the Louisville Courier Journal, workers fiddling with pipes running through a vacant, privately owned farm in Jackson County happened across the animal bones during their excavation of the property. The fossils—part of a jaw, a partial tusk, two leg bones, a vertebrae, a joint, some teeth, and a partial skull—were verified as belonging to a mastodon by Ron Richards, the senior research curator of paleobiology for the Indiana State Museum and Historic Sites. The mastodon, which resembled a wooly mammoth and thrived during the Ice Age, probably stood over 9 feet tall and weighed more than 12,000 pounds.

The owners of the farm, the Nehrt and Schepman families, plan to donate the bones to the Indiana State Museum in Indianapolis if the museum committee decides to accept them. Previously, mastodon bones were found in Jackson County in 1928 and 1949. The remains of “Fred the Mastodon” were discovered near Fort Wayne in 1998.

Middle School Student Discovers Megalodon Tooth Fossil on Spring Break

A few million years ago, the megalodon was the most formidable shark in the sea, with jaws spanning up to 11 feet wide and a stronger bite than a T. Rex. Today the only things left of the supersized sharks are fossils, and a middle school student recently discovered one on a trip to the beach, WECT reports.

Avery Fauth was spending spring break with her family at North Topsail Beach in North Carolina when she noticed something buried in the sand. She dug it up and uncovered a shark tooth the length of her palm. She immediately knew she had found something special, and screamed to get her family's attention.

Her father recognized the megalodon tooth: He had been searching for one for 25 years and had even taught his three daughters to scour the sand for shark teeth whenever they went to the beach. Avery and her sisters found a few more shark teeth that day from great whites, but her megalodon fossil was by far the most impressive treasure from the outing.

Megalodons dominated seas for 20 million years before suddenly dying out 3 million years ago. They grew between 43 and 82 feet long and had teeth that were up to 7.5 inches long—over twice the size of a great white's teeth. They're thought to be the largest sharks that ever lived.

Megalodon teeth have been discovered on every continent except Antarctica, but they're still a rare find. Avery Fauth plans to keep her fossil in a special box at home.
