Nearly complete skull of apex carnivore found in Egypt
A nearly complete skull of a leopard-sized carnivore was discovered in the Egyptian desert.
In a rare find, a team of scientists in Egypt uncovered a nearly complete skull that offers insight into a not-before-discovered apex predator species that lived 30 million years ago.
Published on Monday in the Journal of Vertebrate Paleontology, the results of the desert dig painted the picture of a fearsome, big-cat creature with a strong jaw and sharp teeth that occupied the spot at the top of the food chain during the Oligocene Epoch era. Discovered in Fayum, Egypt, the powerful predator would have lived in a then-tropical rainforest environment.
The newly-discovered species, named Bastetodon syrtos, is part of the Hyaenodonta family, an extinct species of carnivore that evolved long before modern cats, dogs and hyenas but resembled early versions of modern big cats. This lineage once ruled the food chain in the time after dinosaurs went extinct, preying on primates, early hippos, early elephants and hyraxes, but were later wiped out themselves.
In life, the Bastetodon was leopard-sized with a short, cat-like snout, hyena-like teeth and a dog-like body.
A 'dream' discovery
The discovery of the most complete skull ever found belonging to the hyaenodonta subfamily hyainailourinae almost didn't happen, according to paleontologist and lead author Shorouq Al-Ashqar from Mansoura University and the American University in Cairo.
"Just as we were about to conclude our work, a team member spotted something remarkable —a set of large teeth sticking out of the ground," she said in a statement. "His excited shout brought the team together, marking the beginning of an extraordinary discovery: a nearly complete skull of an ancient apex carnivore, a dream for any vertebrate paleontologist.'
The team, called Sallam Lab, made the find while digging in the Fayum Depression, a basin in the desert known as one of the most significant fossil deposits in Africa. They chose to name the newly-found species after the ancient Egyptian goddess Bastet, the cat-headed symbol of protection, pleasure and good health.
New skull may help solve extinction riddle
The discovery also prompted Sallam Lab scientists to re-visit the findings on a separate lion-sized Hyaenodont species discovered more than 120 years ago. The team constructed the genus of Sekhmetop, named after the lion-headed goddess of wrath and war Sekhmet, and found that it, like the Bastetodon, originated in Africa and not Europe as 1904 scientists originally thought.
This finding gives scientists some more insight into what exactly happened to the once-fierce king of the jungle and its kin.
Hyaenodonts lived in Asia, Europe, India and North America - the new study demonstrates that Bastetodon and Sekhmetop likely spread from Africa to these regions in waves. The team theorized that "cataclysmic" changes in global climate and tectonic shifts made way for the distant relatives of modern cats, dogs and hyenas to begin evolving. As the environment and therefore its prey changed, hyaendodonts diminished in diversity and eventually went extinct.
"The discovery of Bastetodon is a significant achievement in understanding the diversity and evolution of hyaenodonts and their global distribution,' Al-Ashqa's statement continued. 'We are eager to continue our research to unravel the intricate relationships between these ancient predators and their environments over time and across continents.'

Scientists recreate lost recipes for a 5,000-year-old Egyptian blue dye

For being the world's oldest known synthetic pigment, the original recipes for Egyptian blue remain a mystery. The approximately 5,000-year-old dye wasn't a single color, but instead encompassed a range of hues, from deep blues to duller grays and greens. Artisans first crafted Egyptian blue during the Fourth Dynasty (roughly 2613 to 2494 BCE) from recipes reliant on calcium-copper silicate. These techniques were later adopted by Romans in lieu of more expensive materials like lapis lazuli and turquoise. But the additional ingredient lists were lost to history by the time of the Renaissance. This is particularly frustrating not just for preservation efforts, but because of Egyptian blue's unique biological, magnetic, and optical properties. Unlike other pigments, the Egyptian blue emits near-infrared light wavelengths that are unseen by the human eye, making it a promising tool for anticounterfeiting efforts, fingerprinting, and even high-temperature superconductors. But after studying ancient materials and manufacturing methods, a team led by Washington State University (WSU) researchers in collaboration with the Smithsonian's Conservation Institute and the Carnegie Museum of Natural History have created not just one historically accurate Egyptian blue, but 12 of them. While the results are detailed in a study published in npj Heritage Science, first author and WSU materials engineer John McCloy said the project began as something much more casual. 'It started out just as something that was fun to do because they asked us to produce some materials to put on display at the museum, but there's a lot of interest in the material,' he said in a statement. McCloy and colleagues first consulted both a mineralogist and an Egyptologist to create a list of potential materials to develop the pigments, including mixtures of calcium, copper, silicon dioxide, and sodium carbonate. From there, they varied the ingredient proportions before heating them anywhere from 1 to 11 hours at around 1,832 degrees Fahrenheit—temperatures achievable by ancient Egyptian artisans. Once the mixtures cooled at varying rates, the team analyzed each final result using techniques including X-ray diffraction, electron beam X-ray microanalysis, and X-ray nano-computed tomography. Finally, they compared these samples to a pair of Egyptian artifacts including a piece of cartonnage—a papier-mâché-like material used for items like funerary masks. 'One of the things that we saw was that with just small differences in the process, you got very different results,' McCloy said. For example, cooling rates played an important role in influencing the end color. Slower cooling times offered deeper blues, while quicker cooling produced pale gray and green mixtures. Despite this, the bluest of the 12 variants only required about 50 percent of their ingredients to exhibit blue hues. McCloy's team also confirmed that cuprorivaite—the naturally occurring mineral equivalent to Egyptian blue—remains the primary color influence in each hue. Despite the presence of other components, Egyptian blue appears as a uniform color after the cuprorivaite becomes encased in colorless particles such as silicate during the heating process. 'It doesn't matter what the rest of it is, which was really quite surprising to us. You can see that every single pigment particle has a bunch of stuff in it—it's not uniform by any means,' he added. The results go beyond establishing Egyptian blue recipes that largely mirror ancient examples. McCloy and colleagues hope that these initial 12 variants will be used in conservation work to restore historic relics as accurately and vividly as possible.

UN, Iran and Egypt meet in Cairo to discuss Iran's nuclear program

CAIRO (AP) — Iranian, Egyptian and U.N. leaders met in Cairo on Monday to discuss Iran's nuclear program after a report from the U.N. nuclear watchdog agency said Iran is further increasing its stockpile of uranium enriched to near weapons-grade levels. Rafael Mariano Grossi, the head of the Vienna-based International Atomic Energy Agency, said the agency compiled the report because Iranian's uranium enrichment was an ongoing concern to the IAEA's board of governors. 'We hope that by providing the clarification we will be providing an incentive for clarity, an incentive for a peaceful solution and a diplomatic solution,' Grossi said in Cairo. Iranian Foreign Minister Abbas Araghchi met with Egyptian President Abdel Fattah el-Sissi and Egyptian Foreign Minister Badr Abdelatty, though it was unclear if Araghchi would meet directly with Grossi. The two spoke by phone early Sunday. Araghchi wrote on the messaging app Telegram that he stressed Iran's 'continuous cooperation' when he spoke with Grossi. The confidential IAEA report, which was seen by The Associated Press on Saturday, raised a stern warning, saying Iran is now 'the only non-nuclear-weapon state to produce such material,' something the agency said was of 'serious concern.' Iranian leadership believes the IAEA report is politically motivated by Grossi's hopes to become the U.N. secretary general. Grossi is attempting to attract votes of several members of the U.N. Security Council with the report, the head of Iran's Atomic Energy Organization, Mohammad Eslami, told the official IRNA news agency late Sunday. 'He basically has chosen a political attitude, and this political attitude has led the environment to be more political rather that technical," Eslami said. Omani Foreign Minister Badr al-Busaidi, who is mediating the U.S.-Iran talks, visited Tehran on Saturday to present the latest U.S. proposal for ongoing talks. Araghchi wrote on Telegram that Iran is examining the proposal and crafting a response. The U.S.-Iran talks are an attempt to limit Iran's nuclear program in exchange for lifting of some of the crushing economic sanctions the U.S. has imposed on the Islamic Republic, which have strained relations for almost 50 years. The fifth round of talks between the U.S. and Iran concluded in Rome last week with 'some but not conclusive progress,' al-Busaidi said at the time. Iran's deputy foreign minister published a detailed response Sunday, which rejected many of the report's findings. Kazem Gharibabadi noted that out of the IAEA's 682 inspections of 32 states, 493 were carried out in Iran alone. 'So long as a country's nuclear activities are under the IAEA's monitoring, there is no cause for concern,' he said. 'The Islamic Republic of Iran is neither pursuing nuclear weapons nor does it possess any undeclared nuclear materials or activities.' The IAEA report said Iran as of May 17 had amassed 408.6 kilograms (900.8 pounds) of uranium enriched up to 60%. That is an increase of almost 50% since the IAEA's last report in February. The 60% enriched material is a short, technical step away from weapons-grade levels of 90%. ___ Lidman reported from Dubai, United Arab Emirates.

Archaeologists Found 3 Tombs That Were Hidden Beneath the Sand for 3,500 Years

Here's what you'll learn when you read this story: Egyptian archaeologists discovered three tombs in Luxor from Egypt's New Kingdom. Each tomb came with an inscription to give clues as to the name and position of its inhabitant. Some of the tomb architecture was impressively expansive. Three New Kingdom tombs were recently discovered in Luxor. While that's worth celebrating on its own, it gets even better—researchers found inscriptions in the tombs that help tell the stories of the high-ranking officials that were once buried there. According to a translated statement from Egypt's Ministry of Tourism and Antiquities, the three tombs—discovered in the necropolis of Draa Abu El-Naga on the west bank of Luxor—all come from the New Kingdom (1539 to 1077 B.C.). One is from the 19th Dynasty, led by the Ramesside family, and the other two are from the 18th Dynasty. The 19th Dynasty tomb belonged to Amun-em-Ipet—an official who likely worked in the temple or the estate of Amun. While much of the funerary furniture and decorations had faded or been destroyed over time, artistry that was still visible depicted scenes of offering, funerary furniture carriers, and banqueting. The tomb itself was highlighted by a small courtyard that led into the square chamber. The west wall once featured a spot to hold funerary goods, but it was destroyed during later reuse. The two 18th Dynasty tombs were similar in design. One belonged to a person named Baki, who was likely a granary silo supervisor. Baki's tomb is more complex than the one from the 19th Dynasty, with a long hallway-styled courtyard leading to a second courtyard ahead of the main entrance. The tomb then turns and opens into a long chamber with a funerary room. The third tomb belonged to a person called Es, who had a longer list of responsibilities and was known to be a key official in the Temple of Amun in the oasis, the governor of the northern oasis, and a scribe. The tomb closely mirrors that of Baki, and features a small courtyard containing a well, followed by the tomb's main entrance, and then a transverse hall leading to another (incomplete) longitudinal hall. Mohamed Ismail Khaled, the Secretary General of Egypt's Supreme Council for Antiquities, said that experts will continue to study the carvings and hope to gain more information about the tomb's owners. Sherif Fathy, Egypt's Minister of Tourism and Archaeology, called the find by a scientific and archaeological achievement that will greatly contribute to attracting more visitors to the region.
