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.

A WWII Navy Submarine, Lost for 75 Years, Has Been Discovered Off the Coast of Japan

The U.S. Navy lost 52 submarines during World War II, many of which are still missing today. But as The New York Times reports, the wreck of the U.S.S. Grayback—a submarine that disappeared along with its 80-person crew in 1944—has been found off the coast of Okinawa, Japan.

On January 28, 1944, the Grayback departed from Pearl Harbor for its 10th combat patrol. It missed its scheduled return date that spring, and after weeks of failing to locate the vessel, the Navy declared it was likely lost.

Immediately following World War II, the U.S. military studied Japanese war records in search of clues that might lead them to their missing ships. One recording clearly states the Grayback was brought down by a bomb dropped by an Japanese aircraft, and it even gives the longitude and latitude of the attack. But due to a poor translation of the audio, the Navy went looking for the sub 100 miles away from its actual resting place.

Seventy-five years later, the submarine's coordinates were finally uncovered in old Imperial Japanese Navy files.

A Japanese researcher named Yutaka Iwasaki noticed this error while looking at the World War II records of the Imperial Japanese Navy base at Sasebo. He was asked to review the files for the Lost 52 Project, an organization dedicated to finding lost World War II submarines. Using the newly uncovered information and an autonomous underwater vehicle, the team was able to locate the vessel at the bottom of the East China Sea near Okinawa.

Lost 52 doesn't hunt for submarine wrecks with plans to recover them. Rather, the goal of the project is "documenting and preserving the story of the Lost 52 WWII Submarines, leaving a foundation of knowledge for future generations." In the case of the Grayback, the site where it settled on the seafloor will be protected from any human interference.

Swedish Divers Just Discovered Two Shipwrecks That Might Be Related to the Famous Vasa Warship

In 1625, King Gustavus II Adolphus of Sweden commissioned shipbuilders to create the most beautiful, lethal flagship that ever existed, as a symbol of Sweden’s naval strength. Three years later, crowds gathered to watch the Vasa, named after Sweden’s royal house, set sail for the first time. But less than a mile into its maiden voyage, the poorly and hastily constructed warship sunk to the bottom of the Baltic Sea, where it remained until 1961 when it was salvaged and later transported to the Vasa Museum.

Now, the Guardian reports Swedish maritime archaeologists from Vrak—Museum of Wrecks have located two shipwrecks in the Swedish archipelago outside of Vaxholm that could be linked to the Vasa. This is because the shipwright responsible for the Vasa built three other ships, the Äpplet, the Kronan, and the Scepter (though, unlike their ill-fated sibling, they actually made it into battle).

“It was like swimming around the Vasa ship,” maritime archaeologist Jim Hansson said in a museum press release. They believe the first wreck they discovered may be the Äpplet, and the second wreck could be either the Kronan or the Scepter.

“We think that some of them were sunk in the area,” Patrik Hoglund, another Vrak archaeologist, told the Guardian. But these ships didn’t capsize because of shoddy engineering or even an enemy attack. Instead, experts believe the Swedish navy intentionally sunk them after they were decommissioned, so their wrecks would function as surprise spike strips to damage approaching enemy ships.

The divers brought back wood samples from the wrecks to send to a laboratory for testing. Once they know when and where the timber came from, they can cross-reference the data with Swedish archives to find out if it matches information from the Vasa.

Even if the warships do turn out to be the Vasa’s long-lost siblings, it’s unlikely that they’ll be salvaged and displayed alongside it, since the Baltic Sea’s brackish waters actually preserve them much better than a museum could.

Sweden isn’t the only nation that boasts a beautiful shipwreck or two—here are 10 other shipwrecks around the world that you can visit.
