This is the last of the ammonites that I received from my Hungarian friend. Scaphite hungadrianus is a heteromorph type ammonite. This means it's shell does not form a neat spiral that is contained in a single plane. The ammonite started out with a normally coiled shell but then at some point it abandoned the coil and grew straight for a bit before returning to a coil. This is best illustrated in the third picture below. The specimen comes from near Pénzesgyőr, Hungary and was found in sediments from the Aptian stage of the Cretaceous.
I found a cool series of videos on You Tube that were created by a local fossil hunter in Hungary. One of them focuses on collecting at Pénzesgyőr.
Thank you Karoly for the cool specimen!
