Archaeopteryx was decided as original bird but it subsequently classify as Archaeopterygidae (始祖鳥科) under Reptilia (爬行綱) on 1871, after 10 years of the discovery of first fossil in Germany. Archaeopteryx lives in Late Jurassic Period (晚侏羅紀) around 155 million to 150 million years ago mostly inhabits in Europe, when there were islands nearest Equator. Now 11 fossils are discovered and store in individual museum.

The pictorial postmark illustrated what does Archaeopteryx look like, Rehburg-Loccum and Eichstätt are the places in Germany discover fossil of Archaeopteryx.

Thanks to Wolfgang who sent me these two first day covers with special pictorial postmark.
