3" Heteromorph Rarest Of Fossil Ammonites Barremain Age Morocco Ancyloceras

Location: Agadir, Morocco Weight: 7.9 Ounces Ammonite Dimension: 3 Inches long, 1.5 Inches Wide, 0.5 Inches Thick  Cretaceous Barremian Stage (117-113 million-year-old) The items pictured are the ones you will receive.  This is a real Ammonite Fossil. This is Heteromorph Ancyloceras (Audiloceras) ammonite. It has what is known as a heteromorph shape. While most ammonites have spiral shells that retain the same shape throughout growth homeomorph), a major group of ammonites, the Ancyloceratina, emerged during the Late Jurassic that had uncoiled shells and was called heteromorph ammonites (different-shaped). While little is known of their mode of life, uncoiled shells would have precluded fast swimming. They may have wobbled their way through the water column with out-splayed tentacles, sweeping whatever came within their reach into their hungry mouths. As with all ammonites, these went extinct at the end of the Cretaceous.
