Fossils of birds dating back 30 million years have been discovered.

Polish researchers have just discovered the fossil of a new bird species that lived on Earth 30 million years ago near the city of Rzeszow.

This information was published in a recent issue of the Polish scientific journal Ornithology.

The previously unknown bird species, belonging to the Passeriformes order, is named Resoviyaornis Yamrozy, after the city of Rzeszow, pronounced Resoviya in Latin, while Yamrozy is named after the surname of paleontologist Albin Yamroza, who discovered the fossil of this bird on the banks of a small stream near the city of Rzeszow.

According to the theory, this bird drowned in the ocean that, in ancient times, covered the southeastern region of present-day Poland. Scientists believe that Resoviyaornis Yamrozy lived on Earth during the late Paleogene (or Paleocene) - Oligocene (or Apocyn) period, approximately 38 to 25 million years ago.

Zbigniew Bochensky, a scientist at the Institute of Systematization and Evolution of the Polish Academy of Sciences, said that the Resoviyaornis Yamrozy bird was the size of a sparrow with long legs, indicating that it lived more on the ground than in flight. The shape of its beak also suggests that the bird ate insects and berries.

To date, Resoviyaornis Yamrozy is the third Oligocene bird species of the Passeriformes order discovered by scientists.

Researcher Bochensky emphasized that this discovery by Polish scientists is valuable information about the early evolutionary stages of the Passeriformes order, currently the most diverse order in terms of species number on Earth. For every 10,000 birds today, nearly 5,400 belong to the Passeriformes order.
