Fossilised Sponge Sp. Siphonia-Upper Chalk, Fontmaure, Vienne, France, Cretaceous Period

A beautifully preserved example of the extinct sponge Siphonia from the Upper Chalk of Fontmaure, Vienne, France, dating to the Cretaceous Period (~100–66 million years ago).

This specimen features a partially polished face, revealing the sponge’s intricate internal structure and providing a clear view of its characteristic tube-like features.  The sides and reverse of the sponge have been left natural to provide a striking contrast. The fossil displays a rich red-orange coloration, with natural variations of mineralisation throughout.

The Upper Chalk of Fontmaure, Vienne, France, formed during the Cretaceous Period (~100–66 million years ago) and represents a shallow marine environment that was once part of the European continental shelf. Fossils from this region preserve a variety of marine life, including sponges, molluscs, and fish, offering a glimpse into the rich ecosystems of the Late Cretaceous seas.

Combining both scientific interest and aesthetic appeal, this specimen is ready for display or study and is presented with its original label.
