VERY RARE: Pachydiscus neubergicus Fossil Ammonite – Maastrichtian, Cretaceous – Tercis-les-Bains, France – Certified Authentic Specimen

Description

This listing features a VERY RARE specimen of Pachydiscus neubergicus, a remarkable fossil ammonite from the Maastrichtian stage of the Late Cretaceous Period (~72 to 66 million years ago). This exceptional fossil was discovered at Tercis-les-Bains, Landes, France, a locality renowned for its highly significant marine fossil deposits that mark the uppermost Cretaceous stratigraphy.

Pachydiscus belongs to the family Desmoceratidae and is known for its large, thick-shelled, coarsely ribbed appearance. This genus was widespread in the Late Cretaceous seas and is critical for biostratigraphic studies due to its rapid evolutionary changes. Pachydiscus neubergicus is particularly important for correlating Maastrichtian rock layers globally.
