Geological & Scientific Information:
Fossil Type: Ammonite
Species: Hammatoceras speciosum
Order: Ammonitida
Superfamily: Hildoceratoidea
Family: Hammatoceratidae
Geological Stage: Lower Toarcian (approx. 182.7 – 174.1 million years ago)
Biozone: Speciosum Subzone of the Bifrons Zone (this species is the index fossil for the subzone)
Period: Jurassic
Locality: Ligron, Sarthe, Pays de la Loire, France
Depositional Environment: Offshore marine basin with calcareous, fine-grained sediments deposited under moderate to low-energy conditions, often linked to the Toarcian Oceanic Anoxic Event (T-OAE)
Morphology & Notable Features:
Planispiral, evolute shell with broad whorls
Strong, radial ribbing that bifurcates across the flanks
Large umbilicus with well-defined suture lines
Venter often rounded or keeled depending on preservation
Characteristic of the genus Hammatoceras, particularly speciosum, which is widely recognised for its distinctive ornamentation and biozone significance
Scientific Significance:
Hammatoceras speciosum is a key biostratigraphic species used to define the Speciosum Subzone of the Toarcian Bifrons Zone. It is highly important for correlating marine Jurassic strata across Europe.
The species is well documented in classic 19th-century paleontological literature and continues to be a benchmark ammonite for stratigraphers and collectors alike. Its association with the Toarcian Oceanic Anoxic Event also adds value for paleoenvironmental studies.
Ideal For:
Collectors of rare European ammonites
Biostratigraphic or academic reference material
Geological and paleontological displays
Museums or higher-education teaching collections
What You Will Receive:
The exact Hammatoceras speciosum fossil shown in the photos
Certificate of Authenticity
Secure and professional packaging for safe transport

Jurassic Information
The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
