Description
SPECIMEN IDENTIFICATION
This fossil block features Xipheroceras and Promicroceras calcite ammonite material from the Black Ven Marls, Lower Lias, Jurassic Coast. The specimen is associated with Black Ven, Lyme Regis, Dorset, UK, making it an appealing addition for collectors of ammonites, Jurassic fossils and British geological specimens.
The product name identifies this as a Xipheroceras and Promicroceras Calcite Ammonite Fossil block. The inclusion of two named ammonite forms makes this an interesting display piece for anyone building a collection focused on Jurassic marine fossils, ammonite diversity or the geology of the Dorset coast.
GEOLOGICAL CONTEXT
The Black Ven Marls are part of the Lower Lias exposed around the Jurassic Coast at Black Ven near Lyme Regis. The Jurassic Coast is internationally recognised for its significant geological exposures and fossil-bearing strata. Its coastal rocks provide an important setting for studying the history of ancient marine environments and the organisms preserved within Lower Jurassic deposits.
Ammonites were extinct marine cephalopods with coiled shells. Their fossils are widely valued by collectors because they combine distinctive form, scientific interest and a direct connection with the geological history of the rocks in which they are found. Xipheroceras and Promicroceras are the identified ammonite names supplied for this fossil block, giving the specimen a clear focus for collection and display.
COLLECTED AND PREPARED SPECIMEN
Your specimen was discovered by our own team members, Alister and Alison and has been cleaned, prepped and treated by Alison.
The preparation work allows the fossil block to be presented as a practical collector’s specimen while retaining its connection to the Black Ven Marls locality. It is suitable for display in a fossil cabinet, study collection, educational setting or geological-themed interior. The specimen can also serve as an engaging starting point for learning about ammonites, the Lower Lias and the fossil heritage of Lyme Regis.
COLLECTOR AND DISPLAY APPEAL
This Xipheroceras and Promicroceras fossil block is suited to collectors seeking genuine Jurassic Coast material, British fossils, Lyme Regis specimens or calcite ammonites. Its locality information provides useful context for cataloguing and makes it more than a decorative geological object. It can be displayed alongside other Jurassic fossils, ammonites, marine invertebrates and specimens from the Dorset coast to create a locality-focused collection.
The block is also a thoughtful gift for fossil enthusiasts, geology students, amateur palaeontologists and anyone interested in the Jurassic Coast. The named fossil identification and supplied locality details make it suitable for specimen labelling, classroom discussion or personal research into Lower Lias palaeontology.
