After 20 Years, the Largest Dinosaur Foot Ever Discovered Has Been Identified

In 1998, paleontologists unearthed a fossil in Wyoming that experts agree is still the largest dinosaur foot ever discovered. Comprising 13 bones, the nearly complete fossil is 3 feet wide. And researchers say they've finally figured out who it belonged to.

As Gizmodo reports, the massive foot was likely that of a brachiosaur that roamed the Black Hills mountain range 150 million years ago. Brachiosaurs were sauropods that used their long necks to reach vegetation growing up to 40 feet off the ground. They could grow 80 feet long and weigh 88 tons.

The process of identifying the foot, which researchers explain in the journal PeerJ, took so long only because paleontologists in the West are digging up more fossils than they have time to study. When they finally got around to examining the foot bones, they made CGI models of them with a 3D scanner and compared them to other known examples of sauropod feet.

Though they're confident the foot comes from a brachiosaur—any member of the genus Brachiosaurus—scientists haven't been able to link it to one specific species.

This may be the biggest foot fossil ever found, but that doesn't necessarily make this species of brachiosaur the dinosaur with the largest shoe size. Foot fossils are rare: Because they're smaller and they're extremities, feet are more likely to be washed away or picked off by scavengers than other parts of the body. So while titanosaur and argentinosaurus, the largest known dinosaurs, almost certainly had more colossal feet than this brachiosaur, their actual foot fossils have yet to be discovered.

15th-Century Cannonballs Likely Used by Vlad the Impaler Discovered in Bulgaria

Dracula was known for using his fangs and supernatural powers to dispatch his victims. But he apparently liked to have a few cannonballs by his side as well (just in case).

No, there’s no secret passage from Bram Stoker’s novel involving a battle where the vampire count displays his firepower. Rather, according to the website Archaeology in Bulgaria, cannonballs were recently excavated from the Bulgarian town of Svishtov, the site of a military conquest made by the Romanian prince Vlad III. Known more popularly as “Vlad the Impaler,” he likely served as the inspiration behind Stoker's bloodthirsty antagonist.

During his reign as one of most ruthless rulers in history, Vlad III frequently butted heads with the Ottoman Turks. The conflict came to a violent head in 1461, when Vlad and his army fought for control over Svishtov’s Zishtova Fortress. Now, as Gizmodo reports, archaeologists say they've uncovered a collection of centuries-old cannonballs that may have belonged to Vlad and were most likely linked to the event.

The cannonballs themselves were shot from culverins, medieval cannons that fired missiles weighing up to 16 pounds, which were relatively light compared to later models. Lead archaeologist Nikolay Ovcharov of the National Institute and Museum of Archaeology in Sofia said that's what makes these artifacts particularly exciting.

“We rejoice at those small cannonballs because they are from culverins," Ovcharov told Fox News. "These were the earliest cannons which were for the 15th century, up until the 16th century, [and] they weren’t in use after that.”

That battle occurred as an attempt to reclaim the region from the occupying Turks. The region was occupied as far back as the Roman Empire and was abandoned after barbarian invasions. The Zishtova Fortress was built much later, and Vlad III made it his home—after he reclaimed it from his enemies.

But just because Vlad may have had cannonballs at his disposal doesn't mean that some of the battle's victims weren't impaled.

"[We] have a letter by Vlad Dracula to the king of Hungary in which he boasted that he had taken [the fort] after a fierce battle, and that about 410 Turks were killed during the siege," Ovcharov said. "Some of them were probably impaled, in his style."

Easter Island Statues Are Being Threatened By Nose-Picking Selfie-Seekers

Though geographically tiny at just 64 square miles, Easter Island, or Rapa Nui, is home to a rich a history that's been attracting visitors for centuries. Now, one of the top experts on the island warns that inappropriate behavior from tourists could harm the ancient site, HuffPost reports.

Jo Anne Van Tilburg is an archaeologist who first visited Rapa Nui in the early 1980s. Her team has studied the Easter Island heads (known as moaiup close and uncovered the bodies buried beneath them, revealing that the full moai statues are actually up to 33 feet tall.

As Van Tilburg shared in a recent interview on 60 Minutes, a lot has changed since she first set foot on the island. In the early 1980s, Easter Island received about 2500 visitors a year; in 2018, 150,000 tourists flocked there to see the mysterious artifacts. That many annual visitors wouldn't be a lot for some destinations, but on Rapa Nui, an island with a permanent population of 5700 that relies on a generator for power and a limited water supply, those numbers can be devastating.

To make matters worse, many guests act in disrespectful ways when they arrive. According to Van Tilburg, it's not unusual to see tourists illegally climbing on top of the statues and pretending to pick their noses for selfies. "I am troubled by the lack of genuine tourist interest in the island and its people," Van Tillburg said. "There is a lack of genuine appreciation for the Rapa Nui past.”

The island's scarce resources and delicate ecosystem have long been a problem for the people who live there. This may have even led to the site's iconic statues: A recently published study posits that the moai were positioned in certain spots to mark precious sources of fresh water.
