Breydia crassornata Ammonite Fossil: Bajocian Dorset Certificate of Authenticity – Inferior Oolite Burton Bradstock UK Specimen

Description

Breydia crassornata Ammonite Fossil

Middle Jurassic Specimen from Burton Bradstock, Dorset

This carefully selected Breydia crassornata ammonite is a genuine fossil specimen from Burton Bradstock in Dorset, UK. It comes from the Inferior Oolite Group and dates to the Bajocian stage of the Middle Jurassic. The combination of identified species, geological unit, age, and British coastal locality gives the piece a strong collecting context. The supplied photographs show the actual fossil you will receive.

Breydia crassornata Identification

The fossil is identified as Breydia crassornata, an ammonite from the Middle Jurassic. Ammonites were extinct marine cephalopods related broadly to living squid, cuttlefish, and nautiluses. Their familiar coiled shells were divided internally into chambers, while the living animal occupied the outer body chamber. Ammonites developed many different shell forms through geological time, and their fossils are valued for their visual appeal as well as their importance in understanding and correlating sedimentary rock successions.

Bajocian Middle Jurassic Age

The Bajocian is a stage within the Middle Jurassic. This geological placement connects the specimen with a marine world that existed long before the modern Dorset coastline developed. Ammonites were abundant and varied inhabitants of Jurassic seas, and their evolving forms provide palaeontologists with useful evidence when studying the relative ages of marine rocks. A clearly recorded Bajocian specimen is therefore well suited to a collection arranged by geological period, stage, fossil group, species, formation, or locality.

Inferior Oolite Group Geology

This ammonite comes from the Inferior Oolite Group, an important succession of Middle Jurassic sedimentary rocks in southern England. The word oolite refers to rocks that may contain small rounded carbonate grains formed in moving marine water, although individual beds within a geological group can vary in composition and fossil content. The recorded Inferior Oolite provenance gives this specimen a meaningful stratigraphic setting and links it to the ancient marine environments represented by the Jurassic rocks of Dorset. Burial in sediment, mineral processes, rock formation, erosion, and eventual discovery all contributed to the fossil’s present geological character.

Burton Bradstock, Dorset, UK Locality

Burton Bradstock lies on the Dorset coast, an area internationally associated with exposed Jurassic geology and fossil collecting. The recorded locality adds an important geographical dimension to the Breydia crassornata identification, Bajocian age, and Inferior Oolite context. It is an appealing choice for collectors building a display of Dorset fossils, British ammonites, Middle Jurassic marine life, Inferior Oolite specimens, or classic UK fossil localities. The species, geological group, stage, and locality can be retained together on a collector’s label for an informative cabinet display.

The Actual Fossil Shown

All three photographs show the exact Breydia crassornata specimen supplied with this listing, not a generic example or substitute fossil. Please study every image for full sizing information and to assess its individual form, preservation, colour, natural texture, and visible surface detail from different views. Fossils are unique natural objects, so the features shown in the photographs form part of the character and collecting appeal of this exact piece.

Collector Display and Educational Value

This ammonite can be displayed as a stand-alone cabinet fossil or included in a Middle Jurassic, British fossil, Dorset, Inferior Oolite, ammonite, or marine invertebrate collection. It also provides an engaging educational object for discussing extinct cephalopods, stratigraphy, sedimentary geology, fossilisation, marine ecosystems, British palaeontology, and geological time. A padded specimen tray, secure display stand, labelled drawer, or protective cabinet can help present the fossil while reducing unnecessary handling.

Authenticity and Certificate of Authenticity

This is a genuine fossil specimen and includes a generic Certificate of Authenticity card with a lifetime guarantee. The certificate provides lasting reassurance for the collector, while the supplied photographs document the exact fossil being offered. Handle the specimen carefully and support it securely whenever it is moved. Avoid aggressive cleaning techniques, because its natural preserved surface is central to its authenticity, geological history, scientific interest, and individual character.
