LYTOCRIOCERAS Heteromorph Ammonite – Hauterivian Cretaceous, Agadir Morocco
PLN zł240.78
Presenting a rare and visually captivating heteromorph ammonite fossil of the genus LYTOCRIOCERAS, from the Hauterivian Stage of the Early Cretaceous Period. This genuine fossil was discovered near Agadir, Morocco, an area renowned for its fossil-rich marine strata.
Taxonomic Classification:
Order: Ammonitida
Superfamily: Ancyloceratoidea
Family: Ancyloceratidae
Genus:Lytocrioceras
Geological Context:
Period: Cretaceous
Stage: Hauterivian (~132–129 million years ago)
Depositional Environment: Shallow to mid-shelf marine conditions. Fine-grained carbonate and marl sediments created ideal preservation conditions for fragile ammonite shells. These ammonites were likely slow-moving and drifted in the open sea, with shell morphologies adapted to low-energy pelagic lifestyles.
Morphological Features:
Classic heteromorph form with loosely coiled early whorls transitioning into more elongated, hook-like shaft segments
Ornamented with fine ribbing and tubercles, and suture patterns may be visible in well-preserved examples
Irregular coiling is a key identifier of the genus and a subject of evolutionary interest, as it reflects non-standard buoyancy and ecological strategies in ammonites
Scientific Significance:
Lytocrioceras is part of the heteromorph ammonite radiation during the Early Cretaceous, showcasing experimental shell forms outside the standard planispiral coil
These fossils aid in biostratigraphic dating and palaeobiogeographic studies, especially across the Tethyan marine realm
Locality Information:
Agadir region, Morocco – a prolific fossil site with exposures of Early Cretaceous marine sedimentary rocks, often yielding ammonites, belemnites, and other invertebrates in excellent condition
Authenticity & Display:
All of our fossils are 100% Genuine Specimens and are accompanied by a Certificate of Authenticity. The images included show the actual specimen you will receive. Please note that the scale cube = 1cm and full sizing details can be found in the photographs.
This is a carefully selected piece of palaeontological history, perfect for ammonite collectors, fossil enthusiasts, or those with an interest in the diverse evolutionary forms of the Cretaceous seas.
Own a true relic of marine life from over 130 million years ago—a rare and beautiful example of Lytocrioceras.

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.
