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.

March 31 Deadline For Wyoming’s ‘Becoming An Outdoor Woman’ Workshops
Gaining the knowledge to become an outdoorsy type of person isn’t easy. It takes time, dedication, and the desire to sometimes get out of your comfort zone. Sure, if you grew up in the outdoors, but it’s been a while since you’ve actually been out hunting, fishing, hiking, or camping, you may be a little rusty, but you have a leg up on those who haven’t.
If you’re in Wyoming, there’s a good chance that taking advantage of the incredible outdoor activities we have available has crossed your mind, but where to start is the big question. Asking others for help is one way, but there’s sometimes an element of intimidation or embarrassment involved.
If you’re a woman looking for that help and want to avoid the intimidation, you should really check out the Wyoming Game and Fish Department’s Becoming an Outdoor Woman (BOW) workshops this summer. It’s held at the Whiskey Mountain Conservation Camp near Dubois, and everything you need to learn about the outdoors is provided, including food and lodging.
The registration deadline is March 31, meaning you have just a couple of weeks to apply for one or all of the offered workshops.
There are multiple options available depending on your level of outdoor knowledge.
Basic BOW Workshop: Introductory level camp teaching outdoor survival, basic fly fishing, backpacking, how to shoot, outdoor photography, and more. There will be two of these workshops, June 5-7 and August 7-9. $150
Fly Fishing Beyond BOW Workshop: The focus here is on fly fishing. Learn the basics and then put them to use. This workshop runs July 30 – Aug 2. $150
Backpacking Beyond BOW: This workshop is all about backpacking, hiking, cooking on the trail, adjusting to the trail, and preparing for the trip. You’ll learn how to properly pack your bag, set up camp, and then head out on an overnight trip. July 30 – Aug 2. $150
Become a BOW Instructor: Here’s where you put your years of experience to work by sharing your skills and knowledge with others, helping them learn the tricks and tips of the outdoors.
Not only will these workshops help get you started on a life in the outdoors, but you’re likely going to gain some street cred with your family when you can teach them the skills they’ll need to get out and celebrate a Wyoming lifestyle.

Snowpack In The South Laramie Range At Just Three Percent Of Normal Levels
The snowpack in the South Laramie Range in southeast Wyoming as of Monday was at three percent of normal, according to the Cheyenne Office of the National Weather Service.
And while other mountain ranges in southeast Wyoming were not nearly that low in snowpack, they were still well below normal at last report.
The agency posted the following on its website:
February was yet another warm and dry month, continuing the pattern that has dominated our area since last fall. Mountain snowpack remains well below average in southeast Wyoming, especially in the Laramie Range where snowpack is at an all time record low. For the plains, some light snow fell last month, but it was not enough to keep from increasing seasonal snowfall deficits. Cheyenne is off to its 4th least snowy start to the season since records began in the 1880s, and Scottsbluff has received the 2nd least snow since record began in the 1890s. We are now approximately two-thirds of the way through the snow accumulation season, with a little more than one-third to go in March, April, and into early May.
But the good news is that after a wet 24 hours on Monday night/Tuesday, more snow may be headed our way on Friday.
