Description
Solenopora jurassica of the kimmeridgian composed of limestone tinted with phycoerythrin, red pigment resulting from the body.
The solenopore is a blue alga, close to the stromatolites which lived in the seas rich in limestone of the middle and upper Jurassic.
Very decorative, this specimen comes from Saint-Jean d’Angely in Charente-Maritime.
