Geological Setting – Middle Bajocian, Jurassic Seas of Dorset
This ammonite comes from the famous fossil-bearing coastal exposures around Burton Bradstock, a renowned Jurassic locality on the Dorset coast. The rocks here date to the Middle Bajocian, approximately 168 million years ago, when southern Britain was submerged beneath a warm, shallow tropical sea.
During the Middle Jurassic, Dorset’s marine environment supported thriving communities of ammonites, bivalves, echinoderms, and marine reptiles. Fine sediments accumulated on the seabed, burying shells quickly and allowing excellent fossil preservation.
Burton Bradstock is particularly well known among collectors for producing large, robust ammonites such as Parkinsonia, making specimens from this locality highly desirable worldwide.
Fossil Species – Parkinsonia Ammonite
Parkinsonia is a distinctive genus of Jurassic ammonite belonging to the extinct subclass Ammonoidea, within the class Cephalopoda. Ammonites were marine molluscs related to modern squid and cuttlefish and were among the most successful predators of the Mesozoic oceans.
Parkinsonia is especially prized for its bold ribbing, strong whorl structure, and characteristic shell ornamentation. These ammonites are classic index fossils of the Middle Bajocian, widely used by geologists to date and correlate Jurassic strata across Europe.
Their elegant spiral form and well-defined rib patterns make them among the most attractive ammonites available to collectors.
Morphology and Display Features
This specimen’s large 5.5 inch size gives it exceptional display impact, ideal as a centrepiece fossil. The ammonite preserves:
- Strong ribbed ornamentation across the shell
