A 330-Million-Year-Old Shark Head Was Found Inside a Cave in Kentucky

Kentucky is synonymous with fried chicken and horse racing.

Apparently we need to add sharks to the list.

Scientists recently discovered a shark skull inside a cave in Kentucky that dates back quite a few years. And we’re not talking a few decades.

The 330-million-year-old skull was found in the 400-mile long Mammoth Cave National Park, which just so happens to be the longest known cave system in the world.

Rick Olson and Rick Toomey, who both work as Mammoth Cave scientists, found the fossil. John-Paul Hodnett led a team of paleontologists in identifying the fossil as one that originated in the Late Missisippian geological period that occurred between 358 to 323 million years ago.

Hodnett could hardly contain his excitement over the unique discovery.

“There’s hardly ever any record at all of sharks’ teeth coming from these rocks,” he told CNN. “So this is a brand new record of sharks from a particular layer of time.”

The Rick duo that found the fossil buried within the limestone cave walls has been hard at work mapping a part of the Kentucky cave system.

Hodnett’s team eventually excavated a 2.5-foot portion of the shark’s jaw. Based on the jaw size, the prehistoric animal would have measured comparably to a modern great white shark.

While the discovery was certainly impressive, it isn’t close to the oldest shark fossil found. Fossilized skin scales of sharks dating back to 450 million years ago were found in Colorado and Central Australia. In fact, the oldest shark teeth on record were found from the Devonian Period, which took place between 418 to 358 million years ago.

“Mammoth Cave has a rich fossil shark record and there’s still much more to uncover,” Hodnett said.

I guess the discovery would qualify as big news, after all.

Australians Have Been Eating a Fish Previously Unknown to Science

Australians already confront crazy-looking (and deadly) animals on a daily basis, so it probably never occurred to them to question a fish that tasted pretty okay and didn’t kill anyone once ingested.

They probably didn’t expect to find out, though, that literally no one had ever heard of or seen the fish before, anywhere in the world.

Well, at least not before 2000, when a fisherman sent pictures of a mystery grouper to fish expert and Queensland Museum curator Jeff Johnson. But even though he saw images of the strange fish a few more times over the years, it wasn’t until 2017 that he got his hands on a physical specimen.

He nabbed 5 of them, actually, at a Brisbane fish market, and set to work identifying the apparently yummy swimmer.

“As soon as I saw them, I thought they were probably a new species, so I purchased all five and began the hard work of formally proving they were a new species,” he said in a statement. “I’ve been told they are quite tasty.”

He and museum geneticist Dr. Jessica Worthington Wilmer worked together to confirm his suspicions, and the new species was named Epinephelus fuscomarginatus.

The new subspecies of grouper isn’t so distinctive looking that people with untrained eyes would notice it straight away, and given that most groupers are fairly generic-looking fish, it’s understandable – if slightly worrying – that no one consuming it gave it a second thought.

The Epinephelus fuscomarginatus is about 27 inches long and lives about 750 feet down along the center of the Great Barrier Reef.

This grouper, interestingly, is not the only species to recently be discovered on its way to someone’s plate. In 2011, a new species of shark was discovered in a Taiwanese fish market, and in 2018, a different shark, thought to be extinct, showed up in a market in Mumbai.

In 2010, researchers discovered a species of monkey that sneezes when it rains, but lost their specimen when the locals in Myanmar ate it.

Oops. Dinner takes precedence over science, you know. I’m not even mad.

Learn About 5 of the Most Notorious Criminals of the past 50 Years

It’s hard to definitively come up with the most notorious American criminals from the past 50 years, but these men and women absolutely belong in the conversation. Each and every one of these killers was responsible for the murders of multiple innocent people, and their names alone still bring up images of death and mayhem.

This list is not complete by any means, but there is no denying that these five criminals shocked and terrified millions of Americans – and people around the world – with their wicked deeds.

1. John Wayne Gacy

Notoroius serial killer John Wayne Gacy was executed 25 years ago today.

Posted by Investigation Discovery on Friday, May 10, 2019

In the annals of American serial killers, John Wayne Gacy remains one of the most terrifying. Gacy worked as a contractor in the Chicago area, and he was active in local politics. He also entertained area children by dressing as a character he called “Pogo the Clown.”

Little did friends, family, and neighbors know that, underneath his normal facade, Gacy was a serial killer who preyed on boys and young men. After murdering his victims, Gacy buried many of them in the crawlspace under his home.

He was finally arrested in December 1978 and was eventually convicted of an astounding 33 murders. Gacy was executed by lethal injection in Illinois in 1994 when he was 52 years old.

2. Aileen Wuornos 

Aileen Wuornos was executed by lethal injection on October 9, 2002.

Posted by Investigation Discovery on Wednesday, October 9, 2019

Aileen Wuornos‘ life story is one of remarkable tragedy almost from the very beginning. She was born to teenage parents in 1956. Soon after, her mother abandoned her, and her father, whom she never met, hanged himself in a prison cell when Wuornos was 12. She ended up being raised by her grandparents, but that was no better; she suffered from sexual abuse from a young age, becoming pregnant at the age of 14.

Wuornos began working as a prostitute when she was only 15, and this twisted her towards a lifetime of depravity. In 1989, after spending some time drifting and some time in jail, Wuornos committed her first murder. Before her capture in a Florida bar in 1991, Aileen Wuornos murdered an additional six men, later claiming that she killed them in self-defense.

Wuornos was convicted and was executed by lethal injection in Florida in 2002, marking the end of a tragic life filled with hatred and violence.

3. Jeffrey Dahmer

Serial killer Jeffrey Dahmer was finally caught on this day in 1991.

Posted by Investigation Discovery on Monday, July 22, 2019

The name Dahmer is synonymous with evil, and there are many reasons why; in fact, there are exactly 16 reasons. That is the number of men that Jeffrey Dahmer killed during a murder spree that lasted from 1987 until his capture in 1991. Dahmer also killed a man in 1978 when he was only 18 years old.

Dahmer lived in an apartment building in Milwaukee, Wisconsin, and that apartment – #213 – became a torture chamber for the men who crossed its threshold. Dahmer picked up many of his victims at gay bars and lured them back to his apartment, where he then murdered them, dismembered their bodies, and – in some cases – ate their body parts.

Dahmer’s neighbors complained of foul smells and loud noises coming from apartment 213. They even heard chainsaws running on occasion. On July 22, 1991, Dahmer’s horrific life as a free man came to an end when he was arrested after a victim managed to escape Dahmer’s apartment before being killed. Arresting officers found a literal house of horrors, filled with severed heads, human hearts, and other body parts and bones.

Dahmer confessed and was sentenced to life in prison. In November 1994, Dahmer, then 34 years old, was beaten to death in a Wisconsin prison by another inmate.

4. Dennis Rader

Posted by Investigation Discovery on Thursday, September 26, 2019

Dennis Rader, also known as “BTK” (Bind, Torture, Kill) is one of the more perplexing serial killers in American history because he followed no specific patterns and some of his murders occurred years apart.

From 1974 until his eventual capture in 2005, Rader kept the citizens of Wichita, Kansas, and surrounding areas in complete terror with his murders and the taunting letters he sent to police and news outlets.

Rader murdered 10 people, including two children, between 1974 and 1991, and he remained a free man for another 14 years before he was captured. A minor slip-up proved to be his undoing: police were able to trace a floppy disk he sent them back to his church, which led to his arrest in February 2005. Rader confessed to his crimes and was sentenced to life behind bars.

Today, Dennis Rader is 74 years old, and he will spend the rest of his days behind bars in a maximum-security prison in Kansas.

5. Charles Manson

Charles Manson's name alone sends a chill down our spines.

Posted by Investigation Discovery on Thursday, May 9, 2019

The fact remains that Charles Manson never actually killed anyone (that we know of), but he was responsible for directing the murders of 7 people and one unborn child over the course of two terrifying nights in August 1969. The murders of Hollywood star Sharon Tate, her friends, and a separate middle-aged married couple shook Los Angeles to its core and captured the attention of the nation.

When the truth came out a few months later that a group of young hippies led by a charismatic ex-convict named Charles Manson was responsible for the murders, Americans were riveted.

A lengthy and dramatic trial ensued and Manson and several of his followers were put behind bars for life. After spending decades in prison in California, Charles Manson died in November 2017 at the age of 83.

13-Year-Old Discovers a Danish King’s Buried Treasure

Talk about the discovery of a lifetime. In January 2018, amateur archaeologist René Schön and a 13-year-old student named Luca Malaschnitschenko were exploring the German island of Rügen in the Baltic Sea when their metal detector hit on something.

At first, the two thought it was simply aluminum, but they later realized they’d stumbled upon a 10th-century coin from a buried treasure that belonged to a Danish king. It wasn’t until a few months later that German archaeologists uncovered the entire hoard of treasure on the island. Schön and Malaschnitschenko were both invited back to take part in the big dig.

The archaeologists uncovered pearls, about 100 silver coins ranging from the 700s to the 900s, a Thor’s hammer, and jewelry. What a find for a 13-year-kid (and his trusty adult helper).

Researchers believe that the treasure trove belonged to Viking-born Danish king Harry Bluetooth, who abandoned the Viking lifestyle and brought Christianity to Denmark. The king fled Denmark in the late 980s, around the time the recently discovered treasure was buried. Bluetooth’s nickname came from a dead, bluish tooth he sported. The Bluetooth technology we all know and love today is named after the former king.
