230 Million-Year-Old Fossil From Wyoming Challenges Dinosaur Origin Theories

Though paleontologists have been discussing the origin and spread of dinosaurs for decades, the widely accepted theory was that they emerged in the southern part of the ancient continent of Pangea over 200 million years ago, and only spread northward millions of years later. A new study dramatically changes the conversation.

University of Wisconsin–Madison (UW–Madison) paleontologists announced the discovery of a new dinosaur that challenges the conventional theory about the dinosaurs’ origin and spread. The location and age of the newly-described fossils suggest that dinosaurs prowled the northern regions of Pangea millions of years earlier than previously hypothesized. The findings were detailed in a January 8 study published in the Zoological Journal of the Linnean Society.

“We’re kind of filling in some of this story, and we’re showing that the ideas that we’ve held for so long — ideas that were supported by the fragmented evidence that we had — weren’t quite right,” Dave Lovelace of the University of Wisconsin Geology Museum, who co-led the study, said in a UW–Madison statement. “We now have this piece of evidence that shows dinosaurs were here in the northern hemisphere much earlier than we thought.”

The paleontologists uncovered the theory-defying fossils in present-day Wyoming in 2013. Due to Earth’s shifting tectonic plates, this region was located near the equator over 200 million years ago on Laurasia, the northern half of Pangea (the southern half was called Gondwana). While the remains were fragmented, the paleontologists were able to attribute the fossils to a new dinosaur species they named Ahvaytum bahndooiveche, which was likely an early sauropod relative. Ahvaytum, however, looked very different from the iconic long-necked herbivores.

“It was basically the size of a chicken but with a really long tail,” said Lovelace. “We think of dinosaurs as these giant behemoths, but they didn’t start out that way.” The adult specimen was just over a foot tall (30.5 centimeters) and about three feet long (91.4 cm).

Perhaps most shockingly, however, is the age of the fossil. Lovelace and his colleagues used radioisotopic dating (a method for determining the age of materials by measuring radioactive decay) to determine that the rock layers where they’d found the Ahvaytum fossils—and thus roughly the remains themselves—were about 230 million years old. This makes Ahvaytum the oldest known Laurasian dinosaur, and about equivalent in age to the earliest known Gondwanan dinosaurs, according to the study. Dinosaurs first emerged during the Triassic period, around 230 million years ago. This era, which lasted from about 252 to 201 million years ago, saw the rise of the earliest dinos, before they became dominant in the Jurassic period.

“We have, with these fossils, the oldest equatorial dinosaur in the world — it’s also North America’s oldest dinosaur,” Lovelace added. The fact that the oldest known Laurasian dinosaur is about as old as the earliest known Gondwanan dinosaurs consequently challenges the theory that dinosaurs originated in the south of the ancient continent and only spread north millions of years later.

The site of the discovery is within the ancestral lands of the Eastern Shoshone Tribe. As a result, the researchers partnered with tribal members throughout their work, and included Eastern Shoshone elders and middle school students in choosing the new dinosaur’s name. Ahvaytum bahndooiveche roughly translates to “long ago dinosaur” in the Eastern Shoshone language.

The region also yielded additional finds. The team identified an early dinosaur-like footprint in older rock layers, meaning that dinosaurs or dinosaur-related creatures were calling Laurasia home even before Ahvaytum. The paleontologists also uncovered the fossil of a newly described amphibian, which was also named in the Eastern Shoshone language.

In challenging long-standing theories about how dinosaurs spread across Pangea, the discovery of the chicken-sized Ahvaytum ultimately paints a clearer picture of the creatures that walked the Earth—and where—millions of years before us.

LARAMIE — Nasir Meyer converted a three-point play with 35 seconds remaining to give Wyoming Cowboys men’s basketball the lead for good, and Wyoming held Air Force Falcons men’s basketball scoreless over the final two minutes to secure a 66-62 victory Saturday night.

The win marked the 13th home victory of the season for Wyoming, which improved to 16-13 overall and 7-11 in conference play.

“Air Force deserves all the credit and let’s talk about a team that has every reason not to fight, but thats why they are Air Force and the cadets and I have a lot of respect for them,” Wyoming coach Sundance Wicks said. “They were not going to quit, and I didn’t drive that message home enough and hats off to Air Force because they deserved to win. We snuck away with a win. Adam Harakow showed when we need him and he was massive for us. Simm-Marten was made big plays and Naz was clutch for us late.”

Wyoming shot 35% from the field and went 7 of 28 from 3-point range, making just two from beyond the arc in the second half. Air Force shot 49% overall and 44% from 3, hitting eight shots from long distance. The Cowboys made 13 of 16 free throws (81%) and scored 22 points off 15 Air Force turnovers while holding a 39-36 edge in rebounding.

Damarion Dennis led Wyoming with 16 points and three assists, going 7 of 8 from the free-throw line. Meyer finished with 14 points and tied a career best with eight rebounds. Adam Harakow added 14 points off the bench on 5-of-6 shooting, his first double-figure scoring game since the first meeting with Air Force. Simm-Marten Saadi had nine points in 13 minutes, and Kiani Saxon grabbed seven rebounds.

Air Force opened with back-to-back 3-pointers to take a 6-0 lead. Meyer scored Wyoming’s first basket, and Leland Walker added a 3-pointer to make it 8-5 with 16 minutes left in the first half.

Wyoming responded with a 9-0 run over nearly four minutes, with Saadi and Harakow each connecting from beyond the arc to give the Cowboys an 11-8 lead with under 14 minutes remaining. Air Force regained a 12-11 advantage as Wyoming went scoreless for more than two minutes.

Harakow’s second 3-pointer pushed the lead to 22-16 with nine minutes left in the half, and Wyoming used a 6-0 run while holding the Falcons without a field goal for more than four minutes to build a 28-18 lead with six minutes remaining. The Cowboys closed the half on a defensive stand, keeping Air Force scoreless for the final two minutes to take a 35-25 lead into the break. Wyoming scored 15 first-half points off turnovers.

The teams traded 3-pointers early in the second half, and Air Force cut the deficit to 40-31 with under 17 minutes left before trimming it to seven 90 seconds later. Walker answered with a 3-pointer to make it 43-33 with 15 minutes to go.

Air Force used a 9-0 run during a stretch in which Wyoming went more than 3 1/2 minutes without a point to pull within one with nine minutes left. The Falcons later tied the game at 51-51 with 5:30 remaining after forcing six straight missed shots.

A pair of free throws by Meyer and a basket from Saadi gave Wyoming a 57-53 lead with under four minutes to play. Air Force answered with three consecutive 3-pointers from Kam Sanders to take a 62-59 lead with two minutes left.

Meyer scored with 90 seconds remaining to cut the deficit to one. On the next trip, he converted an and-one to give Wyoming a 64-62 lead with 35 seconds left. The Cowboys added late free throws to close out the 66-62 win.

Sanders led Air Force with 16 points and nine rebounds, going 4 of 5 from 3-point range. Eli Robinson added 12 points on 5-of-7 shooting.

Wyoming closes its home schedule Tuesday against Nevada Wolf Pack men’s basketball at 8 p.m. as part of a doubleheader with the Cowgirls.

Wyoming Crow Hunters Can Blast All They Want, But Nobody Eats The Birds

Wyoming Crow Hunters Can Blast All They Want, But Nobody Eats The Birds

Mention of bird hunting might conjure up images of hunters and their dogs huddling in freezing duck blinds or pounding the brush in hopes of kicking up pheasants. But crow hunting is a thing in Wyoming too.

“It’s about the sport of it,” Dan Kinneman of Riverton told Cowboy State Daily.

He started crow hunting when he was 14 and is about to turn 85. He’s never tried cooking and eating crows or known anybody who has.

Instead, shooting crows is essentially nuisance bird control, as they’re known to wreak havoc on agricultural crops.

“All the ranchers will let you hunt crows. I’ve never been refused access to hunt crows. They all hate them,” he said.

In Wyoming, crow hunting season runs from Nov. 1 to Feb. 28. No license is required, and there’s no bag limit. Hunters can shoot all the crows they want to.

It’s a ball for hunting dogs too, Kinneman said.

“My yellow Labrador retriever, he doesn’t care whether it’s a crow or duck. In fact, he likes crow hunting more than duck hunting, because there’s more action,” he said.

Crow hunting requires skill, patience and a good set of decoys, an experienced Wyoming hunter said. The upside is, there’s no bag limit, hunters can blast all the crows they want. No one eats them, though.

Don’t Expect It To Be Easy

Kinneman said that in the days of his youth, crow hunting was as simple as driving around and “shooting them out of trees with rifles.”

However, as the number of people and buildings potentially in the paths of bullets grew, such practices fell out of favor. Crow hunting became more regulated.

And it evolved to resemble hunting other birds, such as waterfowl.

Meaning, hunters started setting out decoys, hiding in blinds and using calls to tempt crows to within shotgun range.

Kinneman is no stranger to hunting of all types. He’s taken numerous species of big game in Wyoming and elsewhere. And in July 2005, he shot a prairie dog near Rock Springs from well over a mile away.

He hit the prairie dog from 2,157 yards away. A mile is 1,760 yards.

But bird hunting has always been his favorite.

“It’s my life,” he said.

He has a huge collection of duck, goose and dove decoys. And two tubs full of crow decoys.

The uninitiated might think that going out and blasting crows would be a slam dunk.

That isn’t so, Kinneman said. He likes crow hunting for the challenge of it.

“Hunting crows is hard. They are a lot smarter than ducks and geese,” he said.

Pick Up After Yourself

Even though he doesn’t eat crows, Kinneman said he never just left them littering the ground where he shot them.

“I never let them lay out there. I always picked them up and disposed of the carcasses,” he said.

That’s good ethics and it shows respect for the ranchers, he said.

“Leaving them (dead crows) out there would be no different than just leaving all of your empty shotgun shells out there,” he said.

“You have to pick up after yourself, or the ranchers won’t let you back onto their land,” he added.

Slow Year

At his age, Kinneman isn’t sure how much longer he’ll be able to get out crow hunting. And this year has been a total bust.

“I love doing it. But this year there are no crows,” he said.

The Riverton area is along major crow migration routes.

Picking a good hunting spot is a matter of “finding a flyway” that the crows are on and then setting up a spread of decoys and a blind along the route.

But with an unusually warm winter, the crow flyways have been practically empty, he said.
