This fossil comes from the internationally respected Alice Purnell Collection, and is a prime example of a mid-Jurassic ammonite species with significant palaeontological value.
This authentic fossil is shown in the listing photo—what you see is exactly what you will receive. A scale rule cube (1cm squares) is included in the image for accurate sizing. All of our fossils are backed by a Certificate of Authenticity and are guaranteed to be 100% genuine specimens.
GEOLOGICAL & TAXONOMIC INFORMATION:
- Species: Bullatimorphites bullatus
- Genus: Bullatimorphites
- Geological Period: Middle Jurassic
- Stage: Lower Callovian (approx. 166–164 million years ago)
- Formation/Locality: Deux-Sèvres region, France
- Depositional Environment: Shallow epicontinental marine shelf with fine-grained carbonate sediments; conditions ideal for nektonic cephalopods
- Biozone: Possibly within the Bullatus or Coronatum ammonite zones of the Lower Callovian
- Family: Perisphinctidae
- Superfamily: Perisphinctoidea
- Order: Ammonitida
- Class: Cephalopoda
- Phylum: Mollusca
- Described by: Quenstedt, 1887
MORPHOLOGICAL FEATURES:
Bullatimorphites bullatus is characterised by its distinctive involute coiling and compressed discoidal shell. The species name “bullatus” refers to its inflated whorl section, which can be diagnostic when compared to more compressed Callovian forms. Typical features include:
- Gently convex flanks
- Relatively fine, evenly spaced ribbing
- Rounded venter with no keel
- Moderate umbilicus
- These features make it highly recognisable and of interest for biostratigraphy and evolutionary studies.
NOTABLE ASPECTS:
- A rare species from a classic European Jurassic site
- Excellent preservation of fine morphological features
- Valuable for collectors, museums, and educational use
- Sourced from the well-regarded Alice Purnell Collection
- Includes Certificate of Authenticity
- Photographed specimen is the exact fossil you will receive
SUMMARY:
- Species: Bullatimorphites bullatus
- Age: Lower Callovian, Middle Jurassic (~166–164 Ma)
- Locality: Deux-Sèvres, France
- Formation: Jurassic marine limestone and marl sequences
- Preservation: Fine ribbing and form details intact
- Collection: Alice Purnell
- Authenticity: 100% genuine certified fossil
- Photo: Actual specimen shown – 1cm scale cube included
This Bullatimorphites bullatus ammonite is an excellent collector’s specimen, combining rarity, age, and historical scientific significance. A top-tier fossil for those passionate about Jurassic marine life and European palaeontology.
