Description

Durania ehrenbergii
Miocene
Braunkohle Lignite
Adendorf, Rhineland Germany.

14mm fruit from coal deposit.

Durania was originally described as an extinct plant genus based on a fruit fossil from the Oligocene of Germany but one researcher later identified the fruit as belonging to the modern genus Rehderodendron.  It’s unclear if this has become the prevailing view

Great name in any case.
