Scientist with Field Museums in Chicago In its collection, we found that pigeon-sized horn fossils exhibit a previously unknown set of characteristics regarding early known birds, particularly bird feathers, hands, feet and heads.
Reuters reported Fossils must be one of the best preserved and most complete of the 14 known fossils of specimens identified since 1861.
first Archeopteryx Fossilexhibited reptile-bird-like characteristics, supporting Charles Darwin’s idea of evolution, indicating that the birds evolved from dinosaurs.
New research has made it possible Soft Tissue of Chicago Fossils Using UV light, CT scans allowed scientists to see details still embedded in the rock. This study showed that 164 years after the discovery of the first horn horn fossils, we can learn about creatures that flew during the Jurassic period 150 million years ago.

Anatomical properties indicated that Archeopteryx could have flew, but perhaps spent more time on the ground and could have climbed the tree.
Scientists noted that the fossils exhibited the presence of special feathers on both wings, known as contingent. The hospital is attached to the bone of the humerus bone of the upper arm and is also the innermost flying wing, scientists explained.
However, the small feathered dinosaurs were not contingent. Researchers said the discovery of internal flight wings found in many birds today suggests that areas have evolved specifically for flight.
“To create a lift, the aerodynamic surface must be continuous with the body,” says Field Museum paleontologist Jingmai O’Connor I said. “So, in order to fly to evolve using feather wings, we had to fill this gap, as dinosaurs can be seen in Archeopteryx.

“We have been studying Archeopteryx for over 160 years, and so much basic information is still controversial. Is it a bird? Can it fly? The existence of Tertials supports the interpretation that the answer to both these questions is “yes,” O’Connor added.
When the fossils were excavated, they were preserved in three dimensions rather than flat as many fossils. Scientists were able to protect soft tissue artifacts while preparing them, and the tissues glowed when they hit UV rays.
This species also shows soft tissue in the hand, suggesting that the first and third fingers are mobility and can be used for climbing. The soft tissue of the toe pad has led scientists to believe that the old Gry spent much life on the ground and limited flight capacity.

Another feature the scientists discovered was the palate, or the roof of the mouth, which, unlike many living birds, confirmed that the Archeopteryx skull was not moving. However, there is evidence of The first stage of evolution As seen in modern birds, it is a characteristic that allows the beak to move independently of the brain case.
The Chicago fossil has only a vertebral column of Archeopteryx, which contains two small vertebrae at the tip of the tail.
The museum said it bought the fossil last year and has been in the hands of a series of private collectors since it was discovered before 1990.
“This specimen is definitely Best Archeopteryx ever discoveredand we learn a lot of new things from there,” O’Connor said.

In March 2018, researchers suggested that Archeopteryx could possibly fly, but in a way that is different from modern birds, it is a rapid, short burst of short distances.

Archeopteryx had feathers like modern birds. But it also had “long, hard, foliar feather tail” and teeth, along with unfused hands, shoulders and pelvic bones.
Of the 12 fossils of Archeopteryx discovered, the first was discovered in the late 19th century by the famous German paleontologist Hermann von Meyer. The latest one was discovered by amateur collectors in 2010, published in February 2014, and scientifically explained in 2018.
