Wonderchicken, Meet the Bird of Dinosaur Era, A new species of ancient bird has been identified. A new species of ancient bird has been identified with nearly complete skulls, preserved at three points, and related bones found in Belgium.
Detailed analysis of the skull suggests that it combines land flow and waterfowl characteristics, suggesting that the bird is close to the last common ancestor of modern chickens and ducks.

Asteriornis maastrichtensis is the first modern dinosaur-era bird to be found in the northern hemisphere. Its fossil remains were discovered in a limestone quarry near the Belgian-Dutch border. An evolutionist from the Department of Earth Sciences at Cambridge University.
Daniel Field said: The moment I first saw what was under the rock was the most exciting moment in my scientific life. It is one of the best preserved fossil bird skulls of any age, from anywhere in the world. When we saw it, knowing that it was at such a critical moment in Earth’s history, we almost had to pinch ourselves. “
“Finding the skull has ruined my mind. Without cutting-edge CT scans, we would never have known that we had the world’s oldest modern bird skull,” said co-author Juan Benito, a researcher at the University’s Department of Earth Sciences. from Cambridge and the Rudd Biology Department at the University of Bath. And biochemistry.
The skull of Asteriornis maastrichtensis is clearly recognizable as a modern bird. It adds a number of characteristics to the group, including live chickens and ducks, a group called Gallolencera. “The origins of the variety of live birds are shrouded in mystery, other than knowing that modern birds were born sometime at the end of the dinosaur age.
We have very little fossil evidence of the asteroid until it hits, ”said the co-author and PhD. Student Albert Chen, also from the University of Cambridge and the University of Bath. “This fossil provides our first direct glimpse of what modern birds would have liked during the early stages of their evolutionary history.”
The fact that Asteriornis maastrichtensis was discovered in Europe is another thing that makes it so extraordinary.
“The Late Cretaceous fossil record of birds from Europe is extremely rare. The discovery of Asteriornis maastrichtensis provides some earlier evidence.
And that Europe was an important area in the early evolutionary history of modern birds, “said the author, Dr. Said John Jagt, a researcher at the Natural History Museum in Maastricht, The Netherlands.
“This fossil tells us that at least some modern birds at first were fairly small-bodied, ground-dwelling birds that lived on the seashore. Asteriornis maastrichtensis now provides us with a search image for future fossil discoveries: It is expected to enter a new era of fossils, helping to clarify how, when, and where modern birds evolved.
We are not sure how it would have known, but a fossil bird paleontologist is calling it “Wonderchicken”, which has the distinction of being the first modern example of birds known to science.
The fossil comes from an entire skull that dates back at least a million years to an asteroid, triggering a mass extinction event in the late Cretaceous period, annihilating the large dinosaurs entirely.
Paleontologists have described the skull and the bird to which it belonged in detail, in a new study published Wednesday in the journal Nature. Using X-rays and CT scans, the researchers were able to identify a 66.7 million-year-old bird skull that was hidden in limestone.
Surprisingly, Wonderchicken shares with today’s chickens and ducks, hence its nickname. The study provides new clues to how the Wonderchicken, Asterionis mastictensis, survived the asteroid, while the large dinosaurs were destroyed.
The time of the discovery, which took place in a limestone mine in Belgium, is lead author Daniel Field, a researcher at the University of Cambridge. “The moment I first saw what was under the rock was the most exciting moment in my scientific career,” Field said in a statement.
“It is one of the most preserved fossil bird skulls of any age, from anywhere in the world. When we saw it, knowing it was at such a critical moment in Earth’s history, we almost got to pinch ourselves.”
In addition to the complete skull, the ancient fossil has some small fragments of leg bones. Together, Bones suggests that the characteristics of Wonderchicken resemble the Gallolencera bird group, which includes modern chickens and ducks.
The Wonderchicken was probably the “mash-up” of the two, Field said. Researchers say old bones tell a new story about what life was like before the asteroid that changed everything. And it gives new clues about the development of birds at that critical moment.
“This fossil tells us that initially, at least some modern birds were small-bodied birds that lived on land and lived on the seashore,” Field said. The location of the skull is also revealing. Fossils from the late Cretaceous period are difficult to reach Europe, the researchers say, so fixing the species of this bird in Europe during this time is illuminating.
Field said that is good for future research. “The asteroid now gives us a search image for future fossil discoveries,” he said. “Hopefully, it marks the beginning of a new era of fossils, describing how, when and where modern birds evolved.” At 67 million years old, the oldest modern bird is the natural ‘Turducken’ ever found.
Approximately 66.8 million years ago, not before the end, before the Cretaceous extinction that wiped out all non-avian dinosaurs, a humble, quail-shaped bird found an unfortunate and unwelcome ending.
But the relatives of this pint-shaped creature, a recently described fossil, are called “Wonderchicken,” which help to sow the permanent and diverse lineages of birds that still fill the skies of the modern world.
Now the oldest known member of the contemporary branch of the avian family tree, Wonderchicken (formally Asterornis maastrichtensis) can help today’s paleontologists better understand how birds pose an extinction threat, that Earth Purifies three-quarters of all species of plants and animals on the surface of..
As such, the beautiful, ancient fossil “represents one of the great discoveries that have taken place in a fortunate life,” Yia University paleontologist Gyamo Bharata-Anjan Bhullar told Cara who was not involved in the study. The New York Times explains it.
Birds first appeared on the paleontological scene about 150 million years ago, making their debut with a delightful area like Archeopteryx, which likely resembled its more reptilian-looking dinosaur ancestors, according to Gizmodo, reports George Dvorsky.
However, sometime during the Cretaceous, our feathered friends began to clench their teeth, bony tails, and claw feathers in favor of more humble features. But the evidence for these ancient aviaries is greatly reduced, leaving a huge hole in the origin story of modern birds.
Wonderchicken is ready to fill this gap.
The fossil, which resided within a rock ledge, first discovered in 2000, was discovered by paleontologists Daniel Field and John Jagat, who decided to investigate its contents. After scanning the Rock block, which contained some broken limb bones that had protruded, the couple were shocked to discover an almost completely preserved skull, only a couple of inches long.
Skull from the face of a chicken or turkey on the head of a duck, the skull is in a way a natural “turdcan”, and remarkably modern, Field, Jagt and their coworkers report in this week’s Nature magazine. As the guard tells Nicola Davis of the Guardian, the bird’s long, slender legs point to a possible habitat on the coast.
According to Gizmodo, this mix of features places the Wonderchain, which was probably the size of a sea c, presumably near the evolutionary junction where waterbirds (like ducks) and land (like chickens). The positivist position of the fossil in its lineage, as well as the impact of the closely following asteroid, gave the team its name as Asterornis, a node for Asteria.
The Greek goddess of shooting stars who became a quail. gone. At least one other modern-looking Cretaceous bird is known, an organism called Vejavis iai, which came after Wondercheon for almost 200,000 or 300,000 years and left a bone fragment in the rocks of what is now..Antarctica.
According to Guardian, derived from the sediment of Europe, Asterians extend the avian timeline and indicate that today’s birds can thrive in the northern hemisphere rather than the south. Although some more fossils may one day change history.
The new findings suggest that birds may have shed some important features in just a short period of time, which happened hundreds of thousands of years before space rock shook Earth.
This is an incredibly informative specimen that was not included in the paper, said Amy Balanoff, a paleontologist at Johns Hopkins University, who tells Gretchen Vogel in the journal Science. It gives us some clues as to who will survive. The characteristics of C were important.
This discovery is reported in an article in the journal Nature.
