ACRIOCERAS TABRELLI Heteromorph Ammonite – Lower Hauterivian Cretaceous, Morocco
£48.00
For sale is an authentic and scientifically valuable heteromorph ammonite fossil, ACRIOCERAS TABRELLI, originating from the Lower Hauterivian Stage of the Early Cretaceous Period. This striking fossil was discovered in Morocco, a region renowned for its diverse and well-preserved ammonite fauna.
Taxonomic Classification:
Order: Ammonitida
Superfamily: Ancyloceratoidea
Family: Acrioceratidae
Genus & Species:Acrioceras tabrelli
Geological Context:
Period: Cretaceous
Stage: Lower Hauterivian (~132–130 million years ago)
Depositional Environment: Marine outer shelf to slope setting. Fine carbonate sediments accumulated in low-energy, open marine environments, allowing the preservation of delicate ammonite forms like Acrioceras. These ammonites likely lived in mid-water zones and were adapted for a planktonic or weakly nektonic lifestyle.
Morphological Features:
Classic heteromorph structure with open helicoidal coiling, gradually transitioning into more linear, curved shaft sections
Strong ribbing and nodose ornamentation, with complex suture lines on well-preserved specimens
Irregular coiling and spacing are considered evolutionary adaptations that may have affected buoyancy and mobility
Scientific Notes:
Acrioceras tabrelli is a key index species for biostratigraphy in Lower Hauterivian sequences, particularly within the Tethyan domain
These ammonites showcase the diversity of heteromorph evolution, breaking from traditional planispiral coiling typical of earlier ammonite groups
Locality Information:
Morocco – Cretaceous fossil-bearing formations here are globally recognized for their exceptional ammonite assemblages, often preserved in detail due to minimal tectonic disturbance and fine marine sedimentation.
Authenticity & Display:
All of our fossils are 100% Genuine Specimens and are provided with a Certificate of Authenticity. The images show the actual fossil you will receive. Please refer to the included photo for full measurements—scale rule cube = 1cm.
This is a carefully selected specimen of Acrioceras tabrelli, chosen for its clarity of structure and scientific importance. Ideal for collectors of heteromorph ammonites, palaeontology enthusiasts, or educational institutions.
Own a genuine relic from over 130 million years ago—an excellent addition to any fossil collection or natural history display.

Cretaceous Information
The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
