New Sauropod Dinosaur Discovered in Wyoming: Ardetosaurus viator | Sci.News


Paleontologists have identified a new genus and species of sauropod dinosaur from a semi-articulated specimen found in the 1990s in northern Wyoming, the United States.

The newly-described species roamed Earth during the Late Jurassic epoch, some 150 million years ago.

Dubbed Ardetosaurus viator, this dinosaur was a type of diplodocid, a family of sauropod dinosaurs that includes some of the longest creatures ever to walk the planet.

“Sauropods are among the best studied dinosaurs and include the largest terrestrial vertebrates throughout most of the Mesozoic,” said Tom van der Linden of the Oertijdmuseum and his colleagues.

“They are best recognized by their long necks and long tails, and their success can be attributed to their extreme size, an intricate bird-like air sac system, as well as their unique feeding and digestive strategies and oviparous reproduction.”

“Sauropod remains have been found on every continent, including Antarctica.”

“One of the most recognizable sauropod families is Diplodocidae, erected in 1884, and currently defined as ‘all diplodocids closer to Diplodocus than to Dicraeosaurus’.”

“These sauropods are generally characterized by their extremely long necks and even longer tails.”

“Diplodocid paleontology is a vibrant field of study, with many recent contributions on morphology, histology, biomechanics, pathologies, and ecology.”

“Diplodocids are known from North and South America, Europe, and Africa, and have a temporal range from the Oxfordian to possibly the early Valanginian (161 to 135 million years ago).”

“They became highly abundant and taxonomically diverse in the Upper Jurassic Morrison Formation of the western United States during the Kimmeridgian and Tithonian (155 to 145 million years ago).”

The remains of Ardetosaurus viator was excavated in 1993 from the Howe-Stephens Quarry in the Morrison Formation.

Ardetosaurus viator is the first skeletally mature sauropod specimen described from the Howe-Stephens Quarry,” the paleontologists said.

“This specimen sheds light on the variability of morphological features in diplodocine sauropods such as laminar capture in the cervico-dorsal transition and laminar transitions in caudal vertebrae,” they added.

“Additionally, the specimen preserves a relatively rare first chevron with a peculiar morphology, which in comparison with other sauropods and other non-avian dinosaurs, highlights the need to further investigate the possible recognition of sexual dimorphism in sauropod dinosaurs through micromorphological characteristics in chevrons.”

The team’s paper was published this month in the journal Palaeontologia Electronica.

Wyoming women escape black bear attack on their tents in the Big Horn Mountains


BILLINGS — Two Wyoming women escaped unharmed after a black bear attacked their tents in the Big Horn Mountains while they were still inside.

Friends Maggie Bassett and Shonna Dehl were on a camping trip when the bear began tearing into their tents while they were asleep on Sunday night.

“It was so scary,” Bassett said.

Basset said it jolted them and their four dogs awake and that both women were shocked at the bear’s behavior.

“It wanted in the tents,” Dehl said. “That’s all it wanted. It didn’t matter what we did.”

Dehl and Bassett proceeded to yell and scream at the bear, even firing gunshots in its direction in an effort to scare it away. None of those efforts worked.

“It was not scared at all,” Bassett said Wednesday afternoon in an online web call. “It didn’t even blink. It just kind of circled around and came back at me from a different angle.”

“It was circling us,” Dehl said. “It felt like it was circling our campground.”

Eventually, the bear scattered away after more gunshots were fired. Then, the two women fled to their vehicle, hiding out for a couple of hours and honking their horn to keep the bear away.

“We were in there for at least an hour,” Dehl said. “Just scared and shaking.”

Eventually, the two drove away unharmed and made their way to Dehl’s family cabin a few hours away.

When they returned the next day, they found their tents collapsed and torn to shreds. Wyoming Game and Fish responded and told the two women they plan to trap the bear and relocate it.

Both Bassett and Dehl said it was a frightening ordeal, especially because they followed all bear-aware protocol, including using bear containers.

“I will never forget that sound of my tent being ripped open,” Bassett said.

Chrissy Webb with Montana Fish, Wildlife and Parks has not been involved in the investigation but said a bear’s memory can bring it back to places where it has encountered unnatural foods before.

“You know it’s not unreasonable for a bear to return to a site where they’ve gotten food in the past,” Webb said. “When bears start accessing those unnatural human-based food is when we start to see bears that can be potentially dangerous because, you know, they’ve got conditioned by this food.”

Webb said there is no way to know if that is what happened in this case, but staying bear aware is crucial for both campers and the animals.

“It’s safer for you to store things properly, and it’s better for the bear’s sake if they’re not able to access those human foods,” Webb said.

For Bassett and Dehl, it’s an experience that has changed the way the two plan to go camping in the future.

“I don’t see myself sleeping in a tent anytime soon, maybe never,” Bassett said.

“Yeah, we’re going to need four walls,” Dehl said.

Wyoming coal company wins federal money to extract critical minerals from Powder River Basin – WyoFile

Wyoming coal company wins federal money to extract critical minerals from Powder River Basin – WyoFile


Coal mining giant Peabody Energy, with massive operations in Wyoming’s Powder River Basin, is among five entities that will share a total of $75 million from the U.S. Department of Energy to advance production of rare-earth elements and critical minerals.

As of press time, it wasn’t clear exactly how much Peabody might receive from the department’s Office of Critical Minerals and Energy Innovation, but it will be added to the $6.25 million in taxpayer money granted to the company earlier this year via Wyoming’s Energy Matching Funds program for the same project.

Peabody plans to build a pilot processing facility at its Rawhide mine just north of Gillette to extract rare earth and critical minerals from coal, according to a Peabody document submitted to the state. It would produce “market-ready mixed rare-earth concentrate,” which can be further refined to produce oxides and metals used in modern technology. Once complete, the facility would support 55 new jobs, Peabody says.

“Coupled with the Wyoming Energy Authority grant awarded earlier this year, this [DOE grant] selection reflects the meaningful progress Peabody has made in advancing promising unconventional rare earth and critical mineral opportunities,” Peabody President and Chief Executive Officer Jim Grech said in a prepared statement this week.

The DOE’s support of Peabody’s effort in Wyoming demonstrates the value of Wyoming coal beyond burning it to generate electricity, Wyoming Mining Association Executive Director Travis Deti said.

“Whether it be energy or the domestic supply chain for needed critical minerals and rare earths, Wyoming coal will be needed for the foreseeable future,” Deti told WyoFile. “Of course this all translates into jobs and revenue.”

St. Louis-based Peabody Energy, with a market value of $2.8 billion, is the largest coal producer in Wyoming and the nation. It owns and operates the Rawhide, North Antelope Rochelle and Caballo coal mines in northeastern Wyoming. Rawhide shipped 7.8 million tons of coal in 2025, according to federal data, while Caballo produced nearly 11.7 million tons and North Antelope scooped nearly 65 million tons. 

Peabody reorganized after filing for bankruptcy and laying off 235 Wyoming miners in 2016. Today, the company employs about 1,480 coal miners in Wyoming.

Push for rare earth, critical minerals

Rare-earth elements and critical minerals occur all over the world, typically in minute quantities. The metals are increasingly in demand as building blocks for everything from magnets to batteries in devices like cell phones and MRI machines. They’re also frequently used in military equipment.

The U.S. has lagged behind China in producing and refining the metals, giving China an economic advantage in the rocky relationship between the two nations. The U.S., and the Trump administration in particular, has pushed a rare-earth and critical minerals supply chain buildout toward the top of its mining and manufacturing priorities.

Last year, President Donald Trump issued the Immediate Measures to Increase American Mineral Production executive order while invoking the Defense Production Act to fast-track permitting and help finance mining and processing efforts.

With increasing government and private-sector interest, Rare Element Resources recently built a rare-earth demonstration processing plant near Upton. Others are pursuing new mining operations in the Laramie Range and southern Bighorn Mountains. Those are all traditional, hardrock resources. As for Wyoming coal, researchers have known for years that it contains rare-earth and critical minerals, but it’s only a relatively new focus.

Although Ramaco Resources, for years, has said it is reactivating its Brook coal mine near Sheridan to extract critical minerals, Peabody Energy’s entrance into the market brings another level of corporate prowess to the prospect of putting Wyoming on the world map. And the Trump administration’s focus on coal for the metals dovetails with other priorities.

“Today’s announcement advances the Trump administration’s efforts to strengthen the U.S. coal sector,” the Department of Energy said. It “reflects a broader commitment to unlock the value of coal and coal-based feedstocks as domestic sources of critical minerals and materials.”

Gov. Mark Gordon agrees.

“I was happy to support a $6.25 million grant from the Wyoming Energy Authority’s Energy Matching Fund earlier this year to build a pilot processing facility at the Rawhide mine near Gillette,” he told WyoFile this week. “If we are going to get back in the game of supplying our nation’s need for rare-earth elements and critical minerals, we need to look at all sources, including those in and around coal seams. The federal contribution is a great addition to this effort.”

Meantime, Wyoming is investing significant taxpayer money beyond the $6.25 million already granted to Peabody.

Visionary Metals Corp recently received a $250,000 Energy Matching Funds grant for a nickel-and-copper project in the Granite Mountains. Also this year, the Legislature created the Wyoming Rare Earths Fund with $16 million “for commercial deployment projects focused on the processing and separation of rare-earth resources located in Wyoming.”
