Description
Liparoceras Fossil Ammonite from the Jurassic Coast, Dorset, UK
Discover a genuine Liparoceras Fossil Ammonite recovered from the famous Green Ammonite Marls of the Lower Lias on Stonebarrow Cliff, Charmouth, near Lyme Regis on the UNESCO World Heritage Jurassic Coast of Dorset, England. This carefully selected fossil specimen represents an authentic piece of Early Jurassic marine history and showcases the remarkable preservation and natural detail for which the Dorset coast is internationally renowned.
The photographs shown are of the exact fossil you will receive, ensuring complete confidence in the preservation, morphology, colouration, and overall appearance of the specimen. This fossil includes a fully hand-signed Premium Certificate of Authenticity confirming its genuine origin and provenance.
Your specimen was discovered by our own team members, Alister and Alison, on 12 May 2026 and has been professionally cleaned, prepped, and treated by Alison to stabilise and enhance the fossil while preserving its authentic natural character.

Fossil Identification and Scientific Classification
Liparoceras is an extinct genus of ammonite cephalopod belonging to the family Liparoceratidae within the superfamily Eoderoceratoidea and the order Ammonitida. These marine molluscs lived during the Early Jurassic Period approximately 190 million years ago when much of what is now southern England lay beneath a warm shallow tropical sea.
Liparoceras ammonites are particularly recognised for their robust shell morphology, inflated whorls, and strong ribbing patterns. Specimens commonly display broad rounded shell sections with pronounced rib structures that may branch or strengthen across the outer whorls. The shell structure evolved to provide buoyancy and protection while the animal moved through Jurassic marine environments.
The genus is closely associated with Lower Jurassic strata and is highly collectible among ammonite enthusiasts due to its attractive preservation, large shell form, and importance within Jurassic biostratigraphy.
Geological Formation and Jurassic Environment
This specimen originates from the Green Ammonite Marls within the Lower Lias Group exposed along Stonebarrow Cliff near Charmouth and Lyme Regis. These fossil-rich marine sediments were deposited during the Sinemurian Stage of the Early Jurassic within a shallow epicontinental sea that covered much of present-day southern Britain.
The Green Ammonite Marls are internationally famous for producing exceptionally preserved ammonites, marine reptiles, bivalves, crinoids, and other marine fossils. Fine-grained calcareous muds and periodic low-oxygen depositional conditions allowed delicate shell material and marine organisms to become rapidly buried and preserved within the sediment.
Over millions of years, mineralisation replaced or preserved the original shell structures, creating the fossil ammonites recovered today from the cliffs and foreshore of the Jurassic Coast. The Dorset coastline continues to reveal new fossil material through natural coastal erosion and winter storm activity.
Stonebarrow Cliff is particularly respected among collectors and palaeontologists for its rich Lower Jurassic fossil beds and historical significance within British palaeontology.
Preservation and Fossil Features
This Liparoceras specimen has been carefully cleaned and professionally prepared by Alison to reveal the natural ribbing, shell structure, and overall morphology of the fossil while retaining its authentic geological character. Depending on the individual specimen, natural preservation may include visible whorl detail, growth lines, shell compression, mineral replacement, or subtle pyritisation typical of Lower Lias ammonites.
The fossil may retain portions of its original shell material or display mineralised internal structures formed during fossilisation. Natural matrix remnants from the Green Ammonite Marls may also remain attached, providing additional geological context and authenticity to the specimen.
Every ammonite from the Jurassic Coast is entirely unique due to natural fossilisation processes, preservation conditions, and millions of years of geological history.
Genuine Jurassic Coast Fossil Collectible
This genuine Liparoceras Fossil Ammonite is ideal for fossil collectors, Jurassic Coast enthusiasts, palaeontology collections, educational displays, and natural history enthusiasts seeking authentic British Jurassic fossils.
