19-22mm Goniatite Hematite Ammonites Devonian era (Germany)

Goniatite, a subclass of ammonites, is distinguished by its coiled, chambered shell adorned with intricate sutures. These ancient marine cephalopods thrived during the Paleozoic era, particularly in the Devonian period. Hematite, an iron oxide mineral, is often found in sedimentary deposits and is known for its metallic luster and reddish hue. It plays a vital role in the fossilization of ammonites, sometimes providing pigmentation and preservation to their shells. Ammonites, a more diverse group of extinct cephalopods, flourished during the Mesozoic era and are recognized for their spiral shells, which vary in size and complexity. Together, goniatites and ammonites exemplify the incredible biodiversity of prehistoric seas, showcasing the evolutionary adaptations of cephalopods across geological time. These fossils not only offer insights into ancient marine ecosystems but also serve as key indicators for geological studies.
