Description
A stunning 6-inch polished fossil specimen of the extinct nautiloid Cymatoceras, displaying natural iridescence preserved from the Aptian Stage of the Early Cretaceous period. This authentic cephalopod fossil originates from the world-renowned fossil beds near Mahajanga, Madagascar. Known for their excellent preservation and natural beauty, these nautiloids represent a prehistoric marine life form related to modern-day Nautilus.
Cymatoceras is characterised by a globular, involute shell with deep sutures and strong ribs. Its shell often exhibits nacreous luster, a result of fossilisation processes in fine carbonate-rich marine sediments. These features, along with the robust shell form, make it a highly collectible piece, particularly when sourced from the Aptian-aged deposits of Madagascar.
