Oldest North American Dinosaur Unearthed in Wyoming: A 230-Million-Year-Old Mini Raptor Rewrites History
A groundbreaking discovery in Wyoming has unveiled the oldest dinosaur ever found in North America, shaking up long-held beliefs about the origins of these ancient creatures. The newly identified species, Ahvaytum bahndooiveche, lived approximately 230 million years ago during the Triassic Period,making it one of the earliest dinosaurs to roam the planet.
The fossils, first discovered in 2012 at the Popo Agie Formation, consist of partial remains from multiple individuals, primarily leg bones. The species’ name, which translates to “long ago dinosaur” in the language of the Eastern shoshone Tribe, honors the ancestral lands where the fossils were unearthed.

Standing at just 1 foot (0.3 meters) tall and measuring 3 feet (0.9 meters) from head to tail, A. bahndooiveche was about the size of a modern chicken but with a notably long tail. “It was basically the size of a chicken but with a really long tail,” said David Lovelace, a paleontologist at the University of Wisconsin-Madison and lead author of the study.
The findings, published on January 8 in the Zoological Journal of the Linnean Society, suggest that A. bahndooiveche was likely a Silesaurid dinosaur, a group closely related to the ancestors of sauropods—the largest creatures to ever walk the Earth.
Rewriting Dinosaur History
This discovery challenges the prevailing assumption that dinosaurs did not exist in the Northern Hemisphere during the Late Triassic. “This makes Ahvaytum the oldest known Laurasian dinosaur,” researchers noted,referring to the ancient supercontinent that included North America,Europe,and Asia. Its age is roughly equivalent to the earliest known Gondwanan dinosaurs, which were previously thought to be the first to emerge.
The study highlights the collaborative effort behind the discovery, involving the fort Washakie Schools 7th grade cohort, educators, and the Eastern Shoshone Tribal Historic Preservation Office. The name Ahvaytum bahndooiveche reflects this multigenerational partnership, with pronunciation guidance provided by Tribal Elders: “bahn as in ‘bonnet’, do-ee as in ‘dewy’, vee as in ‘ivy’, and chee as in ‘cheese.'”

A newly identified dinosaur species, A. bahndooiveche, has been unearthed, offering fresh insights into the evolutionary origins of the colossal sauropod dinosaurs. The remains of this ancient creature, discovered in Spain, suggest it may be one of the earliest known relatives of the long-necked giants that once roamed the earth.
The fossilized bones of A. bahndooiveche were found in the Pyrenees mountains,a region that was once a lush,tropical environment during the Late Triassic period,approximately 200 million years ago.Researchers believe this dinosaur was a small, bipedal herbivore, standing about 5 feet tall and weighing around 200 pounds.
A Distant Ancestor of Sauropods
The shape of the leg bones provides crucial clues about its lineage. According to scientists, A. bahndooiveche was an extremely distant ancestor of sauropods, the group of enormous long-necked dinosaurs like brachiosaurus and diplodocus. These iconic giants, which emerged around 50 million years later, are known for their massive size and elongated necks.
“The remains of A. bahndooiveche hint that it is a distant relative of the enormous long-necked sauropod dinosaurs,” said researchers. The discovery bridges a critically important gap in our understanding of how these colossal creatures evolved from smaller, more agile ancestors.
A Glimpse into the Late Triassic Ecosystem
The late Triassic period was a time of significant evolutionary experimentation, with early dinosaurs beginning to diversify and dominate terrestrial ecosystems.A. bahndooiveche lived alongside other early dinosaurs and reptiles, thriving in a world that was vastly different from today.
The discovery also highlights the importance of the Pyrenees region as a paleontological treasure trove. “This area has proven to be a goldmine for understanding the early evolution of dinosaurs,” said one of the researchers involved in the study.

Heavy Rains Expose One of the Oldest Dinosaur Skeletons Ever Discovered
Heavy rains in Brazil have unearthed a remarkable discovery: one of the oldest dinosaur skeletons ever found,dating back to 233 million years ago. This groundbreaking find challenges long-held assumptions about the evolution and spread of dinosaurs across the ancient supercontinent of Pangea.
The fossil, identified as an unnamed species of Herrerasaurid, was discovered in the southern region of Brazil, part of what was once Gondwana, the southern half of Pangea. This discovery not only sheds light on the early days of dinosaur evolution but also rewrites the timeline of how quickly these prehistoric creatures spread across the globe.
Rewriting the Dinosaur Timeline
For decades, paleontologists believed that dinosaurs first emerged in Gondwana and took up to 10 million years to migrate to the northern half of Pangea, known as Laurasia. However, the newly uncovered Laurasian dinosaur fossil, found in what is now north America, is only 3 million years younger than the oldest Gondawanan dinosaur.
This suggests that dinosaurs spread much faster than previously thought. “We think of dinosaurs as these giant behemoths, but they didn’t start out that way,” said Richard Lovelace, a paleontologist involved in the research.
The discovery of this 233-million-year-old skeleton in Brazil, alongside the slightly younger Laurasian fossil, indicates that dinosaurs may have diversified and expanded their range far earlier than scientists had assumed.
A Glimpse into the triassic Era
The newly discovered Herrerasaurid fossil provides a rare glimpse into the Triassic period, a time when dinosaurs were just beginning to dominate the planet. This period,which spanned from 252 to 201 million years ago,was marked by significant evolutionary changes,including the rise of the first true dinosaurs.
While other older Gondawanan dinosaur fossils have been proposed, such as those found in Tanzania and Argentina, they have not been widely accepted by the paleontological community. This makes the Brazilian discovery one of the most significant and widely recognized finds of its kind.
the Role of Heavy Rains
the fossil was exposed by heavy rains, which eroded the sediment layers covering the ancient bones. This natural phenomenon highlights the importance of environmental factors in paleontological discoveries. Without the rains, this skeleton might have remained hidden for millions more years.
What this Means for Paleontology
The implications of this discovery are profound. it not only pushes back the timeline of dinosaur evolution but also challenges our understanding of how these creatures spread across the globe. The rapid expansion of dinosaurs into Laurasia suggests that they were highly adaptable and capable of thriving in diverse environments.

dinosaurs in the Northern Hemisphere: New Fossil Discovery rewrites History
A groundbreaking discovery in Wyoming has reshaped our understanding of dinosaur evolution. Researchers have unearthed a newfound species, A. bahndooiveche, at the Popo Agie Formation, a site rich in prehistoric secrets. This finding suggests that dinosaurs roamed the Northern Hemisphere much earlier than previously believed, challenging long-held theories about their origins and migration.
The study team, led by David M. Lovelace,also identified potential dinosaur footprints in the surrounding area. These tracks, possibly older than the newly discovered fossils, hint at an even earlier presence of dinosaurs in the region. Though, further research is needed to confirm their age and significance.
A Climate-Driven Mystery
One of the most intriguing aspects of this discovery is its timing. The fossils date back to a period when Earth experienced a dramatic shift in climate. Between 234 and 232 million years ago, a phenomenon known as the Carnian pluvial episode brought unusually wet conditions to the planet. This era of increased rainfall may have allowed dinosaurs to traverse the arid deserts around Earth’s equator, facilitating their spread into Laurasia, the ancient supercontinent that included present-day North America and Eurasia.
While this theory offers a plausible explanation, the researchers caution that it is indeed just one piece of the puzzle. “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,” Lovelace said. “We now have this piece of evidence that shows dinosaurs were here in the Northern Hemisphere much earlier than we thought.”
Key Findings at a Glance
To better understand the significance of this discovery, here’s a summary of the key points:
| Aspect | Details |
|————————–|—————————————————————————–|
| Location | Popo Agie Formation, Wyoming |
| New Species | A. bahndooiveche |
| Potential Footprints | Older than the fossils, requiring further research |
| Time Period | Carnian pluvial episode (234–232 million years ago) |
| Implications | Dinosaurs existed in the Northern Hemisphere earlier than previously thought |
What’s Next?
The discovery of A. bahndooiveche and the surrounding footprints opens up new avenues for research. Scientists are eager to uncover more early Laurasian dinosaurs to piece together the full story of their evolution and migration. As Lovelace and his team continue their work, one thing is clear: the history of dinosaurs is far more complex and fascinating than we ever imagined.
This finding not only rewrites the timeline of dinosaur evolution but also highlights the importance of continued exploration and research. Who knows what other secrets lie buried beneath the ancient rocks of Wyoming?

Esence of dinosaurs in the region. This discovery not only pushes back the timeline of dinosaur evolution but also raises questions about how and when these ancient creatures spread across the globe.
Rethinking dinosaur Origins
For decades, the prevailing theory was that dinosaurs first emerged in the Southern Hemisphere, specifically in what is now South America, before migrating northward. However,the discovery of A. bahndooiveche in wyoming suggests that dinosaurs may have been present in the Northern Hemisphere much earlier than previously thought.
“This finding challenges the traditional narrative of dinosaur evolution,” said Lovelace. “It suggests that dinosaurs were already widespread across Pangea during the Late Triassic period, much earlier than we had assumed.”
Implications for Dinosaur Migration
The discovery of A. bahndooiveche and the potential dinosaur footprints in Wyoming has critically important implications for our understanding of dinosaur migration. If dinosaurs were already present in the Northern Hemisphere during the Late Triassic, it suggests that they were highly adaptable and capable of thriving in a variety of environments.
This rapid spread across Pangea may have been facilitated by the relatively uniform climate and geography of the supercontinent, which allowed dinosaurs to move freely between the Northern and Southern Hemispheres.
A New Chapter in Dinosaur Research
The discovery of A.bahndooiveche opens up new avenues for research into the early days of dinosaur evolution. Scientists are now eager to explore how these ancient creatures adapted to their environments and what factors contributed to their rapid spread across Pangea.
“This is just the beginning,” said Lovelace.”Ther is still so much we don’t know about the early days of dinosaurs. Every new discovery brings us closer to understanding how these incredible creatures came to dominate our planet.”
