A fossil that is likely to be found in the same age bedrock as Centroceras is a marine organism such as other types of algae, foraminifera, or marine invertebrates like brachiopods or ammonites. These organisms lived in similar environments and time periods as Centroceras, making them common in the same age bedrock layers.
Centroceras, a type of nautiloid, is known to have been abundant during the Late Ordovician period, approximately 450 million years ago. This period was marked by significant marine biodiversity, and nautiloids like Centroceras thrived in the oceans of that time. Their fossilized remains provide valuable insights into the evolution of marine life.
