Fossils for Sale - High-quality BRITISH and WORLDWIDE Fossils. An impressive selection of fossils, including Ammonites, Trilobites, Belemnites, Fossil Fish, Fossil Shark Teeth, Fossilised Insects in Amber, Dinosaurs, and Reptiles. UK Fossils was formed in 1988 and collects and preps our own fossils in the heart of the Jurassic Coast, collecting fossils from Lyme Regis, Charmouth and Somerset. Our passion for fossils is reflected in our carefully curated collection, which includes some of the rarest and most unique specimens available.
This listing presents a rare and genuine Fossil Goniatite of the species Sporadoceras posthumum, discovered in the Devonian strata near Koła, Poland. Sporadoceras is a genus of extinct ammonoid cephalopods within the order Goniatitida, known for its diagnostic suture patterns and coiled shells.
Planispiral shell with a moderately involute coiling
Fine, closely spaced growth lines and faint ribbing
Lobed and saddled suture patterns characteristic of Goniatitida
Scientific Notes:
Sporadoceras is commonly used in stratigraphic studies as a biostratigraphic marker in Devonian rock sequences
The genus helps delineate important faunal transitions and marine paleoenvironmental conditions
Taxonomy:
Order: Goniatitida
Superfamily: Tornoceratoidea
Family: Sporadoceratidae
Formally Described By: Early 20th-century paleontologists (exact citation varies)
Authenticity & Display:
All of our fossils are 100% Genuine Specimens and come with a Certificate of Authenticity. The fossil shown in the photograph is the exact piece you will receive.
Please see the image for exact sizing – Scale cube = 1cm.
A rare and beautifully preserved goniatite specimen that offers a glimpse into the marine life of the Devonian seas. An excellent choice for collectors, educational displays, or as a unique scientific gift.

Devonian Information
The Devonian Period (419–359 million years ago), known as the "Age of Fishes," was a time of major evolutionary advances in both marine and terrestrial life. The oceans were dominated by armored placoderm fish, early sharks, and lobe-finned fish like Tiktaalik, which had features that helped vertebrates transition to land. Coral reefs flourished, and ammonites became more diverse. On land, the first forests appeared, with early trees like Archaeopteris, leading to a drop in atmospheric carbon dioxide and climate cooling. The first tetrapods (four-legged vertebrates) began evolving from fish, marking a critical step in the evolution of amphibians. The period ended with the Devonian extinction, likely caused by ocean anoxia and climate shifts, wiping out many marine species and reshaping ecosystems.
