Alcmonavis poeschli was a bird thatlivedaround 150 million years ago andlivedin Germany inthe late Jurassic period .
Find and naming
The amateur paleontologist Roland Pöschl, who owns a quarry called Alte Schöpfel on the Schaudiberg near Mörnsheim in Bavaria , systematically searched for fossils there. In November 2017 he found a stone slab with the right wing of a "primeval bird". The piece was prepared by Uli Leonhardt. In 2018 he reported it as a specimen of Archeopteryx , but pointed out the possibility that it could be a new species.
In 2019 the species Alcmonavis poeschli was named and described by Oliver Walter Mischa Rauhut , Helmut Tischlinger and Christian Foth . The name combines the Celtic name of the Altmühl river , which flows through the area of discovery, Alcmona , with the Latin word for bird, avis . The addition honors Pöschl as an explorer. During the lifetime of the now oldest bird, the Solnhofer Archipelago, a subtropical lagoon with reefs and islands, was located there. Alcmonavis was possibly better suited for fluttering than the oldest bird to date, the Archeopteryx .
The fossil was incorporated into the Bavarian State Collection for Paleontology and Geology after it was purchased by the state of Bavaria .
Way of life
Anatomical details indicate that Alcmonavis was able to fly much better than Archeopteryx and thus represents an evolutionary step.
