Rare Large Sporadoceras muesteri Goniatite Fossil – Upper Devonian – Morocco

This striking and rare fossil is a beautifully preserved specimen of the extinct
ammonoid genus Sporadoceras, specifically the species Sporadoceras muesteri. It hails from the Upper Devonian period and was discovered in Morocco, a region well-known for its rich and diverse fossil beds.

Geological Details:


• Species: Sporadoceras muesteri
• Type: Goniatite (extinct ammonoid cephalopod)
• Geological Period: Upper Devonian (~382 - 359 million years ago)
• Formation: Likely derived from the Anti-Atlas region's marine Devonian limestone deposits
• Location Found: Morocco
• Zone/Biozone: Specific zone data not clearly defined for this specimen
• Stage: Possibly Frasnian or Famennian Stage
• Family: Tornoceratidae
• Superfamily: Tornoceratoidea
• Order: Goniatitida

Morphological Features:


• Involute shell structure with gently curved, lobed sutures characteristic of goniatites
• Fine ribbing and smooth whorls
• Prominent suture lines visible, showcasing evolutionary development from nautiloids to more derived ammonoids
• The size and quality make this a particularly desirable collector’s item

Depositional Environment: The fossil was formed in a shallow marine shelf setting, rich in carbonate sediments typical of Devonian warm tropical seas that covered much of what is now North Africa. The conditions promoted exceptional preservation.

Notable Information:


• Goniatites are ancestors of modern cephalopods such as squid and octopus
• The genus Sporadoceras is significant in biostratigraphy for helping to date Devonian marine strata
