Excavating ammonites and other marine fossils in England’s Jurassic Coast.

Excavating Ammonites and Other Marine Fossils on England’s Jurassic Coast

The Jurassic Coast, a UNESCO World Heritage Site, stretches for 95 miles along the southern coast of England from Devon to Dorset. It is renowned for its stunning geological formations and rich fossil deposits, particularly from the Jurassic period. For rockhounds and mineral collectors, this area presents a unique opportunity to excavate and study ammonites and other marine fossils in their natural state.

The Geological Significance of the Jurassic Coast

The Jurassic Coast is a treasure trove of geological history, showcasing nearly 200 million years of the Earth’s past. area consists of sedimentary rocks that provide insights into different geological periods, including the Triassic, Jurassic, and Cretaceous. The fossils found here, particularly ammonites, offer critical information about marine life during these eras.

Ammonites, a group of extinct marine mollusks, thrived between 240 and 65 million years ago. Their spiral shells, which can range from a few centimeters to over two meters in diameter, are found in various states of preservation along the coast. discovery and identification of these fossils rely on a solid understanding of geology and paleontology.

Types of Fossils Found in the Area

Also to ammonites, collectors can find a diverse array of fossils along the Jurassic Coast, including:

Belemnites: These are ancient squid-like creatures, characterized by their bullet-shaped calcite guards.
Ichthyosaurs: Marine reptiles that resembled dolphins, ichthyosaurs were common during the Jurassic period.
Plesiosaurs: Another type of marine reptile, known for their long necks and broad bodies.
Corals and Bivalves: Essential contributors to ancient marine ecosystems, these fossils provide insights into the habitats of the past.

Best Locations for Fossil Excavation

Several notable spots along the Jurassic Coast are densely packed with fossils. Some of the most popular sites include:

Lyme Regis: Known as the Pearl of Dorset, this coastal town is famous for its ammonite fossils. The beaches and cliff faces are excellent spots for fossil hunting.
Charmouth: Just east of Lyme Regis, Charmouth is equally famous for its fossil beds. It attracts fossil enthusiasts and offers beach access to Jurassic sediments.
The fossil forest at Lulworth Cove: An area that has revealed a plethora of marine fossils, showcasing both preservation and variety.

Practical Tips for Collectors

Collecting fossils along the Jurassic Coast requires preparation and respect for both the environment and regulations. Here are essential tips for successful excavation:

Research Regulations: Ensure you understand local guidelines concerning fossil collection. Some areas may have restrictions to protect heritage site integrity.
Use the Right Tools: Bring appropriate tools such as geological hammers, chisels, and safety goggles. A hand lens can help in identifying finer details.
Stay Safe: Coastal erosion can be hazardous. Always stay clear of unstable cliffs, and check tide schedules to avoid being cut off.
Document Your Finds: Keep records of your discoveries, noting the location, layer of sediment, and the type of fossils collected.

Preserving and Displaying Your Fossils

Once you’ve collected fossils, proper preservation is crucial. Many specimens can be delicate, so take care in handling and storing them. Here are a few methods:

Cleaning: Use a soft brush and mild soap to remove dirt. Avoid harsh chemicals that could damage the fossil.
Storing: Preserve fossils in acid-free boxes or wrapping to prevent deterioration over time.
Displaying: Consider using display cases to protect your fossils while showcasing them. Label each specimen with relevant information for educational purposes.

Conclusion

The Jurassic Coast offers an unparalleled opportunity for rockhounds and mineral collectors to engage with Earths ancient maritime history. From discovering ammonites to studying marine reptiles and other fossils, the hands-on experience contributes to a deeper understanding of paleontology and geology. By adhering to local regulations and practicing safe collection techniques, enthusiasts can enjoy a fulfilling experience while preserving the integrity of this remarkable coastline.
