What Was The First Bird?

The remains of the first birds were found in 1861 in a limestone quarry in Bavaria. The second skeleton was discovered in 1877 and almost a century later, in 1956, the third. It is significant that all three skeletons were found at a distance of 15 km.
It is believed that all three skeletons belonged to the same species Archaeopteryx lithographica, in short Archaeopteryx.
This animal lived 150 million years ago.
