Description
Witchellia glauca Ammonite Fossil – Middle Jurassic, Dorset, UK
This genuine Witchellia glauca ammonite fossil is a carefully chosen specimen from the Inferior Oolite Group at Oborne Wood, North Dorset, UK. Dating to the Middle Jurassic Period, Bajocian Stage, Laeviuscula Zone, this fossil represents an attractive and scientifically interesting British Jurassic ammonite from a classic inland Dorset locality. The photograph shows the actual specimen you will receive, making this a desirable piece for fossil collectors, natural history enthusiasts, geology students, educational displays, and anyone interested in authentic UK Jurassic fossils.

This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. It has been selected as an individual natural history specimen, with full sizing shown in the photo. The fossil is supplied exactly as pictured, allowing buyers to view the preservation, shell form, surface texture, and natural character of the actual ammonite being offered.
Species and Fossil Type
Witchellia glauca is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, and nautilus. Ammonites are among the most recognisable fossils of the Jurassic Period and are highly valued for their coiled shells, ribbed ornamentation, and importance in dating sedimentary rocks. The genus Witchellia is particularly associated with the Middle Jurassic and is a well-known component of Bajocian ammonite faunas.
Witchellia ammonites typically display a planispiral coiled shell form, with ribbing that can vary across the whorls depending on growth stage and preservation. In life, the animal would have lived in the outer body chamber of the shell, while the inner chambers helped regulate buoyancy in the water column. Their elegant spiral form, combined with their geological importance, makes them popular with both collectors and students of palaeontology.
Geology and Age
This specimen comes from the Inferior Oolite Group, a famous Middle Jurassic sequence found across parts of southern and western England. The Inferior Oolite was deposited in warm, shallow marine conditions during the Bajocian Stage, around 170 million years ago. These ancient seas supported a rich variety of marine organisms, including ammonites, bivalves, brachiopods, gastropods, echinoids, crinoids, and other shelly invertebrates.
The Laeviuscula Zone is an important ammonite biozone within the Bajocian. Ammonite zones are used by geologists to divide and correlate Jurassic rock layers because ammonites evolved rapidly and were widely distributed in ancient seas. A Witchellia glauca ammonite from this interval is therefore not only visually appealing, but also represents a useful example of Middle Jurassic biostratigraphy.
Locality – Oborne Wood, North Dorset
Oborne Wood in North Dorset is part of a fossil-bearing region associated with the Inferior Oolite Group around the Sherborne area. While Dorset is world famous for its Jurassic Coast, inland localities such as Oborne Wood are also important for Middle Jurassic fossils. These sites provide a different part of Dorset’s geological story, preserving marine life from younger Jurassic rocks than many of the well-known Lower Jurassic coastal deposits.
The Oborne Wood locality gives this ammonite excellent regional interest, especially for collectors of Dorset fossils, British ammonites, Inferior Oolite specimens, and Bajocian cephalopods. Fossils with named locality information are especially desirable because they preserve geological provenance and provide a clearer connection to the original formation and ancient environment.
Scientific and Collectable Interest
This Witchellia glauca ammonite is a collectable British Jurassic fossil with strong geological appeal. Its named species, Inferior Oolite Group provenance, Bajocian age, Laeviuscula Zone association, and North Dorset locality make it suitable for a specialist fossil collection, natural history cabinet, educational geology set, museum-style display, or thoughtful gift for a fossil enthusiast.
Ammonites remain one of the most popular fossil groups because they combine natural beauty with genuine scientific value. This specimen represents an animal that once lived in the warm Jurassic seas covering what is now Dorset, offering a tangible connection to an ancient marine world preserved in stone for millions of years.
