The ancient bird lived about 44 million years ago during the Eosin period. It belongs to an extinct group, called paraortigde, which is a relative of live Galliformes, the group that includes live chicken, turkey, guinea fowl and quail. This fits into a fossil record of intervals of approximately 15 million years in Gallic descent in North America.
“Uintan paraortygid is similar in small living galleries such as quail and mountainous parts,” said Dr. Thomas Stidham, paleontologist at the Institute of Palaeontology and Paleoanthropology of Vertebrates, Chinese Academy of Sciences, and his colleagues.
He probably lived before the development of the great harvest and gizzard we see in chickens and live turkeys, so Utah species probably had a different diet than their living relatives. The first fossils of this group of paratigids are from dry habitats, seahorses and inland forests that show that they had resistance in ecology and diet.
Another interesting aspect of Uintan’s paraortygid is that it resembles the small size of sediments with a similar geological age of Namibia from South Asia and Uzbekistan in Central Asia and the unique shape of other early paraortygid fossils, which are interconnected by all the oceans, they were different.
The researchers said: Persetigida fossils from Europe, Asia, Africa and North America show that the group extended very early in its evolution and crossed the oceans so that it could spread widely. The scapula of the parantagid Untan. A small, distinctive bone was collected from the shoulder waist of the Uintan paraortgid of the Uinta Formation in the Uinta Basin, Utah.
The scientist of the University of the Midwest, Drs. Beth Townsend said: The new Uinta bird not only fills the time gaps, but also helps us better understand the animal community. “The Uinta basin is important for understanding ecosystems in times of global hot temperatures, when forests, primates and the first horses spread over an area that is now a desert.”
“The discovery of this new paraortgid shows us that the small birds that inhabited the ground were part of these ancient forests and could compete with the first mammals for resources.” Dr. “Small abnd incomplete fossils can also provide data to connect global scientific questions,” Stidham said.
The findings were published in Diversity magazine.
The discovery of the smallest known Mesozoic dinosaur reveals new species in bird development. The discovery of a small, bird-like skull, described in an article published in Nature, reveals a new species, the Oculudentavis khungrai, that may have represented the smallest known Mesozoic dinosaur in the fossil record.
While working on fossils in northern Myanmar, Lars Schmitz, associate professor of biology, W.M. The KK Science Department and a team of international researchers discovered an apparently mature skull specimen in Burmese amber. The smallest living bird is the same size as bee sparrows.
“Preserving amber vertebrae is rare, and it provides us with a window into the world of dinosaurs at the lower end of the body-size spectrum,” said Schmitz. “Its unique physical characteristics point to one of the smallest and oldest birds.”
The team studied the characteristic features of the specimen with high-resolution synchrotron scans to determine how the skull of the Oculudentvis dagger differed from other bird-like dinosaur specimens of the time. They found that the shape and size of the eye bones suggested a complete lifestyle.
But they also revealed striking similarities to the eyes of modern lizards. The skull also displays a unique fusion pattern between various bone elements, as well as the appearance of the teeth. The researchers concluded that the small sample size and the unusually never-before-seen combination suggests characteristics.
The discovery represents a specimen that was previously missing from the fossil record and provides new implications for understanding bird evolution, demonstrating extreme miniaturization of avian body size in the development process. Specimen preservation also highlights the ability of amber deposits to reveal vertebrate body size minima.
“No other group of live birds has species with an equally small skull in adults,” said Schmitz. “This discovery tells us that we only have a small glimpse of what small vertebrates looked like in the age of dinosaurs.”
