Dactylioceras atheticum Ammonite (Dactylioceras atheticum)
From: Nuremburg, Germany.
Age: 183 million years old, Jurassic
These blocks containing multiple shoals of the Jurassic ammonite Dactylioceras which are famous from the Schlaifhausen area near Nuremburg in Germany. They have not been cleaned out of the rock but rather have been weathered out by natural acidic groundwater over unimaginable time.
This piece is exceptional with many complete specimens. All ammonites are in situ and have not been stuck on.
