Manuel Quiring

This rare Protrachyceras ammonite, dating from the Lower Triassic, is a fascinating example of prehistoric life. 

Its shell is beautifully preserved, showcasing the intricate and striking structure of raised tubercles that cover its surface. 

These distinctive bumps give the ammonite an almost sculptural quality, enhancing its natural texture and making it stand out as a true marvel of nature. 

The tubercles, arranged in a precise and geometric pattern, form a striking contrast with the smooth curves of the shell, giving it an almost otherworldly appearance.

 As one of the earliest ammonite species to emerge after the mass extinction at the end of the Permian, Protrachyceras offers valuable insight into the recovery and evolution of marine life during the Triassic period. 
This specimen, with its unique surface detail and rarity, is a prized find for collectors and paleontologists alike.

Complete well centered specimen on a 6x6 cm plate.

High quality, many details like  pragmocone still preserved.

This ammonites are very sought after by collectors and very hard to find on market.
