Description
In this picture we conclude the coverage of the true(ammonitine) ammonites. Specifically, the superfamily Acanthoceratoidea and specifically family Collignoniceratidae and specifically the last subfamily Collignoniceratinae. They were characterized by strongly ribbed and tuberculate, evolute shells.Next time we shall be continuing out coverage of ammonites with the final and arguably most bizarre group of ammonites to exist, the Ancyloceratina. The most famous "Heteromorph Ammonites"
