Rare specimen of Palaequorea rygoli, a fossil hydromedusa from the Solnhofen Limestone of Germany, a world-famous Lagerstätte known for preserving delicate soft-bodied organisms.

Fossil jellyfish are exceptionally uncommon due to their soft tissue composition, which rarely fossilizes. This specimen preserves the characteristic umbrella-shaped structure, offering a rare glimpse into Jurassic marine life beyond the more commonly preserved hard-bodied organisms.

Despite its small size, the specimen represents a significant and unusual fossil type, highly appreciated by collectors seeking rare and scientifically meaningful material. The fossil is preserved as a delicate impression on fine-grained limestone, typical of Solnhofen deposits. Preparation has been carefully carried out to maintain the subtle features of the specimen.

An uncommon and distinctive fossil, ideal for advanced collectors, specialized collections, or educational contexts focused on soft-bodied preservation.
