The Archaeopteryx Feather: first trace of the primeval bird by Hwa Ja Götz (MfN)Museum für Naturkunde Berlin
The globally first fossil of a feather was discovered 1860 in a quarry near Solnhofen. It was described in 1861 as Archaeopteryx – "old feather, old wing".

Soon, further discoveries were made. Because Archaeopteryx displays characteristics of both dinosaurs and birds, it is recognized as a transitional fossil (or "missing link").
The main slab of the Berlin specimen has been called the "Mona Lisa" of fossils. Since 2007 the original is on permanent display in the Museum. Do visit it!

History of discovery: The „Berlin specimen“ of Archaeopteryx was discovered between 1874 and 1876 near Eichstätt in Germany. The original finder sold it for the value of a cow (approx. 150 Mark) to a quarry owner, who sold it for 2000 Mark to E.O. Häberlein, who placed it internationally on sale for 20 000 Goldmark. This high price exceeded the financial abilities of several interested museums. In 1879 Werner von Siemens (shown here) financed the transaction, placing the specimen with the Humboldt Museum für Naturkunde in Berlin. After 2 years, the museums could pay the money back and has been the owner ever since. Described in 1884 by Wilhelm Dames, with its excellent preservation of feathers and skull it is considered the most complete and beautiful specimen of Archaeopteryx.
Archaeopteryx, detail of teeth and curved neck (HR 04) by Hwa Ja Götz (MfN)Museum für Naturkunde Berlin
Unlike modern birds, Archaeopteryx has teeth instead of a bill.
The neck is notably curved backwards. When in a dead animal tendons and muscles dry, they will shorten and pull the neck backwards into a strange position. This can also be observed in other fossils.
Archaeopteryx lithographica – the Berlin specimen (2016-09-09) by Hwa Ja GötzMuseum für Naturkunde Berlin
The long tail is a characteristic of dinosaurs, while the tail feathers are typical for birds. In modern birds the vertebrae of the tail are shortened and fused into a single ossification, still bearing the tail feathers.
Archaeopteryx, detail of claws on the fingers (HR 05) by Hwa Ja Götz (MfN)Museum für Naturkunde Berlin
While the long asymmetrical wingfeathers, the elongated arm and the collarbone show a clear similarity with modern birds, the three clawed fingers are a trait of dinosaurs.
Hoatzin (Opisthocomus hoazin) by Hwa Ja Götz (MfN)Museum für Naturkunde Berlin
Among modern birds, only the juveniles of the hoatzin have claws on their wing digits. Some scientists therefore postulated a relationship with Archaeopteryx. This has since been found to be false
The counter slab of the Berlin specimen by Hwa Ja Götz (MfN)Museum für Naturkunde Berlin
The counterslab of the Berlin specimen is partly damaged. Nevertheless, the information it contains is of the highest scientific value.
