Time is vital to the functioning of our everyday lives: from the watches on our wrists to the GPS systems in our phones. Communication systems, power grids, and financial transactions all rely on precision timing. Seconds are the vital units of measurement in timekeeping.

During the middle to the late Cretaceous period, the region of the United States we know now as the Great Plains was submerged under the North American Western Interior Seaway, with Mitchell County, Kansas lying at the edge of the eastern boundary of the water.
Just as the oceans are teeming with life today, so too did the ancient seaway. And also like today, sharks were an apex predator that most marine animals feared. DePaul University professor of paleobiology Kenshu Shimada and Michael Everhart from the Sternberg Museum of Natural History at Fort Hays State University thought they had uncovered the remains of a prehistoric shark species known as Credotus crassidens, which ranged from England to North America. However, when they compared the teeth they had found to known Credotus crassidens teeth, they realized to their delight that they had just found a brand new species of shark, which they named Cretodus houghtonorum in honor of Keith and Deborah Houghton, who owned the land where the specimen was found and donated it to the museum.
The pair of researchers found more than just teeth, which they explained in a paper published in the Journal of Vertebrate Paleontology:
Bigger than the Great WhiteThe teeth, of course, tell us a lot about sharks both living and extinct. But this specimen revealed even more.
Based on the vertebrae, the team estimated the shark’s length at around 17 feet, and that it could have possibly reached 22 feet, bigger than a Great White Shark named Deep Blue estimated to be 20 feet in length and is also a distant cousin of the Credotus along with the Tiger Shark.
Indeed, sharks are vulnerable to extinction today due to the demand for shark fin soup. But if sharks disappear, ocean eco-systems would be thrown into chaos. In addition, Shimada and Everhart believe Credotus houghtonorum engaged in cannibalism before birth, much like modern-day sharks.
But that was not the most exciting part of the excavation. Like a forensic team, Shimada and Everhart had the opportunity to map out a series of events that occurred 91 million years ago, starting with the ingestion of a hybodontid shark by the Credotus, only for the Credotus to die and be scavenged upon by a Squalicorax shark before it, too, succumbed to whatever killed it near the same spot.
That’s a fascinating find that certainly provides a clear picture of the eat or be eaten world of Cretaceous period oceans. These waters were obviously dangerous.

In the end, the scientists understand that without the cooperation of landowners, they would not be able to make discoveries like this one, which is why they hope to foster goodwill among landowners across Kansas and the rest of the world so that further research can shed more light on these ancient eras in Earth’s history and fill in the gaps with new species so we can further understand the creatures living among us today.
Sharks are an important foundational species in the ocean environment. Letting them go extinct would be a great loss. Sharks have survived on this planet for over 91 million years. If they die out now, we only have ourselves to blame and we’ll suffer for it just as much as every species that relies on the ocean. More about sharks on the Great Plains from PBS Eons:

And the mysterious bit is that the man and the woman in the double grave were buried 100 years apart. Vikings often buried important members of their society inside boat graves, which is a mound that covers a longboat. Some of these boats have even been recovered and are currently on display in Denmark at the Viking Ship Museum. In addition to the bodies of the deceased, Vikings would bury items they believed a person would need in the afterlife such as jewelry, livestock, and weapons. As you can imagine, archaeologists get pretty excited when they find a Viking boat grave. And that’s exactly what archaeologists from the Norwegian University of Science and Technology (NTNU) Museum found at a farm known as Skeiet at Vinjeøra on the side of a cliff. Only they didn’t just find one, they found two. First, the team excavated the boat grave of a woman who died during the 9th century. With her was buried a brooch that turned out to be a decorative harness fitting that Vikings likely seized during a raid in Ireland.
Vikings frequently raided coastal lands in the United Kingdom and continental Europe seeking treasure and new territories to colonize, including Ireland. In fact, the Vikings actually saved Ireland from a steep population decline in the 10th century.
The brooch is not the only item in the grave. The woman was also buried with a spinning wheel, a pearl necklace, scissors and the head of a cow. But then the team dug a little bit deeper and were shocked to discover that a man in a similar boat grave had been buried earlier during the 8th century. The woman had been buried in a smaller boat right above him as if the Vikings were reusing the burial mound.
Indeed, what’s even more fascinating is that the man was buried during the Merovingian era, which researchers figured out based on the style of the sword they found in the grave.
The Merovingian kings were a royal dynasty that ruled a large swath of territory in Western Europe, including France from the middle of the 5th century AD to around 751 AD in the middle of the 8th century. And that’s why Sauvage says the mound dates back to that era as well, making it a very rare find.
Sauvage went on to point out that the farm likely belonged to a single family for generations, which means the mound could be a family grave.
Further evidence that the two share a familial relationship is that the woman’s brooch is also from the Merovingian era, possibly being passed down through the years.
However, only DNA testing will tell us for sure.
And we also know that these individuals must have been particularly important because of where the mound is located on the property.
Anyone who looked up at the cliff from the fjord would have seen this burial mound, almost certainly ensuring that the family would be remembered and revered. Either that or they just wanted a nice view in the afterlife. Once again, researchers have found Viking boat graves, which seem to be less rare these days, especially as technology improves. Unfortunately, the mound had been plowed over by farmers for hundreds of years, which is why it had not been found sooner. And this is just one part of the mound. There could be more in the center and the other sides. It’s just a matter of excavating the site further. Until then, we must wait in anticipation.

Popular media love talking about asteroid mining using big numbers. Many articles talk about a mission to Psyche, the largest metallic asteroid in the asteroid belt, as visiting a body worth $10,000,000,000,000,000,000, presumably because their authors like hitting the “0” key on their keyboards a lot. But how realistic is that valuation? And what does it actually mean?
Asteroids are remnants of the formation of our solar system, and while many can be found within the asteroid belt between the orbits of Mars and Jupiter, some cannot. One such object is asteroid (162173) Ryugu, a 1 km-wide near-Earth asteroid believed to have originated in the asteroid belt. However, it has since moved to cross Earth’s orbit, located 300 million km from our planet.
After almost a century of speculation, proposals and searches for dark matter, physicists now know that it currently comprises about 27% of the universe’s mass-energy, with an abundance over five times that of ordinary matter like you, oceans and exoplanets.
Using ESA’s XMM-Newton satellite and NASA’s Chandra spacecraft, German astronomers have observed a supersoft X-ray source designated RX J0513.9−6951. Results of the observations, published on the arXiv preprint server, shed more light on the evolution of this source.
An international team of scientists has published a study highlighting the potential role of iron sulfides in the formation of life in early Earth’s terrestrial hot springs. According to the researchers, the sulfides may have catalyzed the reduction of gaseous carbon dioxide into prebiotic organic molecules via nonenzymatic pathways.
