Fishermen Caught a 10,500-Year-Old Giant Irish Elk Skull—Antlers and All

The Irish elk (megaloceros giganteus) has been extinct in Ireland for about 10,500 years. So you can imagine how surprised two fishermen were when they pulled up their net and discovered a prehistoric elk skull—with antlers attached—as their catch of the day.

As Smithsonian reports, Raymond McElroy and Charlie Coyle were fishing in Ireland's Lough Neagh, a lake near the town of Ardboe, when they thought their net had snagged on a piece of driftwood. However, when they finally managed to hoist it out of the water, they discovered the skull with antlers measuring over six feet across.

"I thought it was the devil himself," Coyle told The Irish Times. "I was going to throw it back in. I didn't know what to do with it."

McElroy, however, recalled that a jawbone of an ancient Irish elk (possibly from the same animal discovered by the fishermen) was caught in the same area in 2014. For the time being, he's keeping the skull in his garage.

This particular elk probably stood about 6.5 feet tall. It's worth noting, though, that the name "Irish elk" is a bit of a misnomer. The animal is actually classified as a type of deer—in fact, the largest deer to ever have existed.

The "Irish" part of the name stems from the fact that fossils of the animal are often discovered in Ireland's lakes and bogs, which help preserve the bones. However, the animals once roamed throughout Europe, North Africa, and parts of Asia. It was roughly the same size as a modern-day moose, weighed about 1300 pounds, and some animals needed a clearance of 13 feet just to squeeze their antlers between the trees.

"Giant antlers aren't great in the forest," Mike Simms at the Ulster Museum tells Belfast Live. "Environmental change is what caused their extinction."

And thus, the Irish elk joined giant sloths, giant beavers, saber-toothed tigers, mastodons, and mammoths in the enormous extinct animals club, never to be seen again (or at least until the next fishing expedition).

Advanced CT Scans Reveal Blood Vessels and Skin Layers in a Mummy's Hand

Mummies hold some intriguing secrets to their pasts, like the food they ate and the diseases they had when they were alive. Now scientists are using a tool originally designed for medicine to get an even deeper look at the clues mummified bodies carry with them into the present day, Gizmodo reports.

In a proof-of-concept study published in the journal Radiology, researchers from the KTH Royal Institute of Technology in Sweden detail how a new-and-improved CT scanning technique can be used to visualize the interior of mummies on a microscopic level. By creating detailed X-ray images, CT scans allow doctors to see inside their patients without invasive surgery. Archaeologists have been using this technology to study delicate ancient artifacts for years, but the level of detail that can be achieved this way—especially when it comes to looking at interior soft tissue—is limited.

The upgraded version of the tech, called phase-contrast CT scanning, measures the phase shift, or the change in the position of a light wave, that occurs when X-rays pass through solid objects. The images generated this way have a higher contrast level than conventional X-rays, which means they capture more detail.

Doctors have been using this 10-year-old technology to examine soft tissues like organs and veins in living patients, but it hadn't been used on a mummy until recently. Working with a mummified human right hand dating back to 400 BCE in Egypt, which they borrowed from the Museum of Mediterranean and Near Eastern Antiquities in Stockholm, the researchers fired up a phase-contrast CT scanner. It produced images with a resolution of 6 to 9 microns, giving a clear picture of the different layers of skin, individual cells in the connective tissue, and the blood vessels in the nail bed—all without damaging the artifact. Previously, researchers looking to study these same tissues in mummies would have needed to use a scalpel.

As Ars Technica reports, a phase-contrast CT scanner is similar in cost to the conventional machine. The study authors hope their work will lead to phase-contrast CT scanning becoming just as common in archaeology as regular CT scanning, potentially creating new research opportunities in mummies that will be discovered in the future and even in artifacts that have already been examined.

A 2.63-Carat Diamond Was Unearthed by a Grandmother at an Arkansas State Park

Visitors to the Crater of Diamonds Park in Murfreesboro, Arkansas clearly have an objective in mind: Excavate one of the diamonds lurking on or beneath the park's soil, the onetime site of a volcanic crater. If they do, it's theirs to keep.

Earlier this month, a 71-year-old grandmother from Colorado made the biggest discovery on park grounds of 2018: a 2.63-carat ice white diamond. And she did it in about 10 minutes.

The retiree, who asked media outlets not to identify her by name, visited Crater of Diamonds with her husband, son, and grandchildren. After briefly scraping away dirt, she saw the gem on the surface. The diamond was so large and clear—roughly the size of a pinto bean—that she assumed it was just a piece of glass. Further inspection by her family and park personnel revealed it was a diamond.

Park officials told press that employees frequently till the soil, which can loosen the gems and allow them to catch the reflection of the sun, making them easier to spot. Roughly 33,000 diamonds have been found by visitors since the park opened in 1972.

It's hard to know the exact value of the diamond. While there is a certain fluctuating value assigned to a carat, appraisers also look at three other "Cs": clarity, color, and cut. A two-carat diamond is often more than double the price of a one-carat diamond because the larger gems are more rare. But tourists have profited from their finds: In 2015, a visitor retrieved a 8.51-carat white diamond that was cut down to 4.6 carats by a jeweler and valued by the American Gem Society at $500,000.
