Description
A rare and scientifically significant specimen of Dipoloceras cristatum, an extinct genus of ammonite from the Upper Albian Stage of the Cretaceous Period, collected from the geologically rich Dorset Coast, United Kingdom.
Dipoloceras is easily recognised by its robust shell and striking ornamentation of coarse ribs and deep grooves. This genus provides valuable insights into ammonite diversity and distribution patterns during the later part of the Early Cretaceous.
All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.
