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.

The Fossil of a Human-Sized Penguin Has Been Unearthed in New Zealand

Penguins are known for looking cute and cuddly, but if the monster penguins of the Paleocene epoch were still around today, they might have developed a different reputation. As The Guardian reports, the fossil of a new species of one of these giant prehistoric penguins was recently discovered in New Zealand, and scientists say it would have gone head-to-head with many adult humans.

The bird, dubbed Crossvallia waiparensis, stood about 5 feet 3 inches tall and weighed about 175 pounds. For comparison, emperor penguins weigh up to 88 pounds and can reach 3 feet 8 inches in height. The prehistoric bird waddled the Earth some time between 66 and 56 million years ago—shortly after the mass extinction event that wiped out the dinosaurs and marine reptiles, which were probably its main predators.

An amateur paleontologist named Leigh Love discovered the creature's fossilized leg bones on New Zealand's South Island. From those fossils alone, a team of scientists from the Canterbury Museum in New Zealand and the Senckenberg natural history museum in Germany were able to estimate the penguin's height and weight and determine that it belonged to a previously undiscovered species. The large leg bones also indicate that the animal was more reliant on its feet for paddling through the water than the penguins of today.

Crossvallia waiparensis is massive by today's penguin standards, but it's not even the largest prehistoric penguin that we know of. When carnivorous reptiles began disappearing from the world's oceans, the waters opened up for new predators like penguins to flourish. Kumimanu biceae is estimated to have weighed about 223 pounds; Palaeeudyptes klekowskii may have weighed 253 pounds and stretched 6 feet 5 inches long.

Scientists Are Creating a 3D Model of an 18th-Century ‘Vampire Witch’ Who Was Tortured to Death

In 2014, archaeologists uncovered a skeleton in Kamień Pomorski, Poland, with a brick wedged in its mouth and stakes driven through its legs. They believed the man was put to death in the 18th century because townspeople thought he was a vampire.

Now, genetic and forensic analysis has shown that the vampire burial site didn't contain a man at all: It was a 5-foot-6-inch, blue-eyed, blonde woman who was at least 65 years old when she died. Newsweek reports that scientists at the Pomeranian Medical University in Szczecin, Poland are now making a 3D computer model of the woman’s skull, which they plan to use to recreate what her face looked like.

The Forensics Genetics Unit at the university will then build her face on a physical model from layers of plastic material and reveal it to the public within the next few months. Andrzej Ossowski, the head of the unit, told the website Science in Poland that he hopes a museum might display the rendering. “We want to show that with the help of modern methods, we are able to replace skeletons that are very common in museums with 3D models based on research,” he said.

He said that townspeople may have killed the woman because they thought she was a witch, and they gave her an “anti-vampiric” burial to prevent her from rising from her grave à la Nosferatu. The brick in her mouth was meant to weigh her down—in other burials a sickle might have been placed across the neck of the body, which would slit the revenant's throat should it try to rise.

We often think of Salem when it comes to witch trials, but they were common throughout Europe before the 19th century, and archaeologists have discovered “anti-vampiric” graves in Poland, Bulgaria, and Italy. Wondering if you might have qualified as a witch during the 17th-century period of Puritan paranoia? Find out here.
