Ammonite pyritisée

L'ammonite pyritisée d'Oulianovsk, dans la région de la Volga en Russie, est un fossile exceptionnel datant d'environ 150 millions d'années, issu des mers du Jurassique supérieur. Au cours de la fossilisation, la coquille de l'ammonite a été progressivement remplacée par de la pyrite, un sulfure de fer aux reflets métalliques dorés. Certains spécimens sont également associés à de magnifiques cristaux de calcite jaune (simbircite), créant un contraste remarquable entre l'éclat métallique de la pyrite et la transparence chaleureuse de la calcite.
