September 2011 marks the 150 years anniversary of the description of an important paleontological discovery - Archaeopteryx lithographica, the first Mesozoic bird recognized by science and considered at the time a compelling proof of Darwin's theory, published just two years earlier.

In 1860 in a quarry near the village of Solnhofen (Bavaria) the faint imprint of a single feather was discovered on a slab of limestone.

Studying this feather (and informed of the discovery of a complete specimen) the German palaeontologist Christian Erich Hermann von Meyer proposed to establish the species Archaeopterix [sic*] lithographica in a short communication dated to 30, September 1861 - even if today it is not entirely clear if the feather can be linked to the specimens of the classic Archaeopteryx discovered in the same geological formation.
