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.

More than 900 personnel working to contain the Elk Fire in Wyoming
More than 900 personnel were working to contain the Elk Fire in northern Wyoming nearly two weeks after the fire started.
In an update Thursday, fire officials said the wildfire is now estimated to have burned 76,378 acres and was 15 percent contained. There were 902 personnel assigned to the fire.
The fire was started in the Bighorn National Forest by lightning on Sept. 27. Ten 10 helicopters, 21 crews, 63 engines, 8 dozers, 12 water tenders, 5 masticators, and 1 skidder are currently assigned to the blaze.
Here’s the latest update from fire officials:
Key Messages: The recording of last night’s community meeting at Big Horn High School can be viewed on the Elk Fire YouTube channel (www.youtube.com/@2024ElkFire/videos) and the Bighorn National Forest’s Facebook Page (Facebook.com/bighornnf).
The percent containment reported decreased from 16 percent to 15 percent because of recent fire growth. Percent containment measures how much of the fire’s perimeter is surrounded by a control line. The perimeter of the fire is 225 miles, with 34 of those miles being contained firelines.
Overnight, the fire crossed the Big Goose River on the southern end of the fire. The night crew was ready and anticipating this forward progression. They completed firing operations to introduce low-intensity fire on the landscape to reduce the fuel load before the active fire got there. The day shift will continue to work in this area, patrolling and mopping up residual hotspots.
Current Situation:
Residents in Sheridan, Beckton, Bighorn, or Story may have noticed more fire activity and smoke yesterday. The fire was very active, particularly on the west side, due to high winds, high temperatures, low humidity. The fire is expected to be active again today, potentially producing abundant smoke. Additionally, the Rocky Mountain Incident Management Team has been implementing strategic firing operations along the northern and southern edges of the fire perimeter, consisting of adding low- to moderate-intensity fire to the ground in targeted areas to remove fuels from the fire and limit its intensity. Firing operations will continue today if weather conditions permit.
On the fire’s northern side, a hotshot crew conducted additional firing operations, and air operations dropped fire retardant yesterday off the 144 Road. Today, the crews will continue to prepare the 144 Road to protect the Little Bighorn Canyon. The established containment line along the northeastern side of the fire perimeter is holding, and there is minimal heat detected in the area.
On the southeastern and southern parts of the fire, mopup and patrolling continues. Firefighting crews will continue to build additional control lines and prepare areas for potential firing and aerial operations that would protect the watershed and associated water-treatment plant structures. Road graders are working alongside firefighting resources to prepare the Red Grade Road.
On the western side of the fire in the Burgess Junction area, structure protection is in place, and more pumps and sprinklers will be installed today. Firefighters remain on scene to protect structures and conduct defensive firing operations if needed.
Weather & Fire Behavior: A cold front is moving in today, dropping temperatures, increasing humidity, and shifting wind direction to the northwest. The shifting, gusty winds will likely increase fire activity and smoke production, particularly on the fire’s west side, directing growth into the Bighorn National Forest. Vegetation remains extremely dry and receptive to burning. The cooler, moister conditions are not expected to reduce fire behavior in areas with timber. For air-quality and smoke information, refer to the AirNow website: airnow.gov.
Evacuations and Closures: Sheridan County evacuation levels did not change Wednesday. For detailed information, view the evacuation map and all news releases on the Sheridan County Emergency Management website: tinyurl.com/2s38bcc5 or call either the Sheridan County Sheriff’s Office (307-672-3455) or Sheridan County Emergency Management (307-752-2174).

Elk Fire moving south, Big Horn, Wyoming residents comfortable but ready
It’s night 12 of the Elk Fire, as firefighters continue to make progress in Sheridan County, Wyoming.
The fire is now at about 77,000 acres and 16 percent contained.
“It’s a combination of the wind and the topography that is moving this fire down the front of the mountains,” said Kristie Thompson, Elk Fire public information officer.
The public had a chance to hear about the firefighting efforts at Big Horn High School on Wednesday night.
Many remain on evacuation notice and nearly 900 continue to battle the fire.
“In Big Big Horn, there is no evacuation status,” Thompson said.
Much of the concern has been near the northeast part of the fire near Parkman and Dayton, but with the fire growing, people in the southeast portion have now had to be on alert.
The incident commander emphasized human life, property, and the Big Goose water treatment facility are priorities.
“The biggest priority for the incident management team is looking at how do we minimize impacts into the Big Goose watershed and the Big Goose water treatment facility,” said Thompson. “Both of those feed water into this entire area, specifically the city of Sheridan.”
Thompson said crews will implement some strategic fire actions in Big Goose Canyon.
“To slowly take fire up the hill towards that main body of the fire at a controlled rate,” Thompson said. “So that way, it does not have the energy to quickly burn down the mountain if it ever wanted. It’s a very important resource that we want to protect.”
In Big Horn, a short distance from Sheridan, it’s fairly normal on the football field for the high school team and for the younger kids practicing football as well.
“I think they’ve kind of been monitoring air quality that was spreading really fast a few days ago,” said Tommy Stipula, whose son was practicing with his youth team. “But, it’s slowed down a lot and so we’re not as worried now.”
And that’s a sentiment for others in Big Horn.
“That fire’s got a long way to go before it starts putting things in jeopardy,” said Ivan Stalick, a Big Horn resident.
Stalick has a different thought about the air.
“I mean, air quality as you see is pretty horrible, but we all have to deal with this and let this thing work,” Stalick said.
While residents feel relatively comfortable, they also know the potential dangers and one woman is selling signs to raise money for firefighters.
“I’ve lived out here for over 20 years and I love this community and this town,” said Kitt Laidlaw, who lives in Sheridan. “And in times like this, it’s amazing how people rally together to help.
The firefighters appreciate the citizen support and crews were out protecting structures including the Big Goose water treatment plant.
“If the watershed above it burns very severely or hot, that can generate enough sediment to shut down or impact that water treatment plant,” said Chief Jon Wardner of the Big Horn Volunteer Fire Department. “ So the team is busy thinking about ways to not let that happen and obviously protecting the treatment plan itself. So that’s been a big success there.”
The Story area was moved into a set status for evacuations and citizens will be alerted and law enforcment will be ready to answer questions if necessary.
