Rare Fossil Block with Heteromorph Uncoiled Ammonites (Discohoplites), Scaphites, Echinoid & Gastropod – Upper Albian, Lower Cretaceous

Description

A rare multi-fossil block containing heteromorph ammonites (Discohoplites), Scaphites, an Echinoid, and a Gastropod, from the Upper Albian Stage of the Lower Cretaceous, collected at Pénzesgyőr, Hungary. This specimen is highly collectable as it preserves a diverse assemblage of marine life from the Cretaceous seas. The fossil pictured is the exact specimen you will receive, supplied with a Certificate of Authenticity.

Fossil Types & Species:

• Heteromorph Ammonites: Discohoplites (uncoiled ammonite)
• Ammonite: Scaphites (heteromorph ammonite)
• Other Invertebrates: Echinoid & Gastropod
• Order (Ammonites): Ammonitida
• Superfamily: Hoplitaceae (for Discohoplites), Scaphitoidea (for Scaphites)
• Families: Hoplitidae / Scaphitidae

Geological Context:

• Period: Cretaceous
• Epoch/Stage: Lower Cretaceous – Upper Albian (approx. 105 to 100.5 million years ago)
• Biozone: Associated with Mortoniceras inflatum Zone, an important ammonite biozone within the Albian
• Formation: Albian marine limestone and marl deposits of Hungary
• Depositional Environment: Shallow marine carbonate platform, supporting a rich and diverse marine fauna

Locality:

• Region: Pénzesgyőr, Hungary

Morphology & Features:

• Discohoplites: Uncoiled heteromorph ammonite with distinctive irregular coiling
• Scaphites: Hooked coiling typical of the genus, with strong ribbing and ventral features
• Echinoid: Preserved test with characteristic radial symmetry
• Gastropod: Coiled shell form, representative of marine snails
• Excellent preservation showing the association of multiple marine species on a single block

Scientific Notes:

• Discohoplites and Scaphites represent classic heteromorph ammonites, which evolved unique uncoiled morphologies in the Cretaceous
• Multi-fossil blocks such as this are rare and provide valuable palaeoecological insights into ancient marine communities

Notable Details:

• A rare fossil block preserving ammonites and associated invertebrates together
• Excellent preservation with clear detail across multiple fossil types
• 100% genuine, natural fossil – no restoration
• Scale Reference: Each square or cube in the photo = 1cm. Please see photographs for accurate sizing

Authenticity & Guarantee: All of our fossils are 100% genuine, responsibly sourced, and professionally curated. Every purchase includes a Certificate of Authenticity. The fossil shown is the exact specimen you will receive.

This multi-fossil block featuring Discohoplites, Scaphites, echinoid, and gastropod is a rare and scientifically valuable specimen from the Upper Albian of Hungary – an exceptional addition for collectors, researchers, or natural history displays.
