How might the Herne Bay area have looked 55 million years ago?
Environment reconstructionEnvironment reconstructionEnvironment reconstructionEnvironment reconstruction


Herne Bay is a small seaside town on the Kent coast, located approximately 9 miles north of Canterbury. The cliffs and foreshore between Herne Bay in the west and Reculver in the east provide an opportunity to explore a prehistoric marine environment dating from 56-54 million years ago. Fossils occur commonly throughout the year especially following stormy conditions when they can be found in large numbers among the pebbles and clay on the foreshore.

The best place to access the beach is at Beltinge - a small suburb of Herne Bay located a short distance east of the town. Parking is available at the end of Reculver Drive from which a concrete path provides access to the beach.

Fossils can be found in either direction of the access point, although the most productive areas occur on the foreshore beneath Beltinge and towards Reculver in the east.

As the retreating tide allows access to the foreshore the iconic Reculver Towers can be seen towards the east (shown below). The towers are all that remain of a 12th century parish church that stood within the remains of an earlier Roman fort. The towers continue to provide a visual navigation marker for ships travelling within the Thames Estuary area.

The geology of Herne Bay

The sediments exposed between Herne Bay and Reculver encompass around two million years of history dating from the late Palaeocene and early Eocene epochs of the Palaeogene period, 56-54 million years ago (see geologic timescale). At this time southern England was located approximately 40°N of the equator, 10°S of its present latitude, comparable to Spain today. The average annual temperature across southern England at this time was approximately 23°C, compared with the present-day figure of around 10°C.

The prehistoric evidence reveals Kent (including Herne Bay) lay beneath a warm, shallow sea, the nearest significant landmass was perhaps 20-30 miles away for much of this time. As a result conditions on the seafloor were relatively undisturbed, allowing fine particles of sediment suspended in the water column to gradually settle; however short-term fluctuations in tidal currents and sea level introduced sand (and pebbles) to the area throughout this time.

Life during the late Palaeocene and early Eocene was abundant, the nearby land was covered by lush tropical vegetation, providing habitat for mammals, birds and insects, whilst in the sea marine life flourished. The diversity of life is represented in the fossils found at Herne Bay which includes both marine and terrestrially sourced organisms, the latter consisting largely of pyritised twigs, seeds and in rare instances insects that were transported by tidal currents.

The earliest deposits belong to the Thanet Formation (Thanetian stage of the Palaeocene epoch) and are best observed on the foreshore and in the cliffs towards Reculver (see figure 1 below). Travelling from east to west the strata dips at a gradient of 3° bringing progressively later (younger) deposits to beach level including the Upnor and Harwich formations, and the London Clay, although the latter is largely obscured beneath sand at beach level.

Fossils occur commonly throughout the various formations, in particular the Beltinge Fish Bed (Upnor Formation) which appears at beach level opposite the access point at Beltinge (below-left). This fossiliferous bed is the source of many shark and ray teeth, bones and pyritised twigs.

Where to look for fossils?

Fossils can be found loose among the pebbles and clay exposed on the foreshore at low-tide, especially after stormy weather when the rough seas have scoured the beach. If possible it's best to coincide a visit with a spring-tide when the sea retreats to its greatest extent, exposing areas of the beach that are otherwise inaccessible. For a relatively low one-off cost we recommend the use of Neptune Tides software, which provides future tidal information around the UK.

The most productive area of the beach occurs immediately opposite the access point described and continues for c.100m towards the west. Fossils can also be found towards Reculver in the east where the sand has been swept away and the Thanet Formation is exposed.

Although fossils are common they're often difficult to distinguish from the sediment, especially if they've been exposed for some time. The photos below demonstrate a typical example, in this instance a partially obscured shark tooth - it's common for just the tip or root to be visible.

What fossils might you find?

The most frequently exposed fossils belong to marine vertebrates, in particular the teeth of Lamniform sharks which hunted in the shallow seas. Although shark teeth occur in large numbers the volume is more reflective of the thousands of teeth a shark may loose in its lifetime. Other fossils include the crushing pallets (usually fragments) of eagle rays, pieces of turtle carapace, twigs, and a variety of benthic fauna including bivalves and gastropods. Below are a selection of finds made during several field trips between Herne Bay and Reculver.

Tools & equipment

It's a good idea to spend some time considering the tools and equipment you're likely to require while fossil hunting at Herne Bay. Preparation in advance will help ensure your visit is productive and safe. Below are some of the items you should consider carrying with you. You can purchase a selection of geological tools and equipment online from UKGE.

Steel point: In some instances it's not necessary to use a hammer and chisel to remove the matrix surrounding the fossil. Sometimes all that's required is some careful precision work using a steel point. This is particularly relevant with crumbly matrix, where chiselling may otherwise shatter a fragile fossil.

Hand lens: A hand lens enables the fossil hunter to enjoy the finer details of the specimens they find. It's often remarkable how well preserved some of the most intricate structures can be. We recommend a lens with x10 magnification that folds away into a metal casing to protect it from damage.

Strong bag: When considering the type of bag to use it's worth setting aside one that will only be used for fossil hunting, rocks are usually dusty or muddy and will make a mess of anything they come in contact with. The bag will also need to carry a range of accessories which need to be easily accessible. Among the features recommended include: brightly coloured, a strong holder construction, back support, strong straps, plenty of easily accessible pockets and a rain cover.

Walking boots: A good pair of walking boots will protect you from ankle sprains, provide more grip on slippery surfaces and keep you dry in wet conditions. During your fossil hunt you're likely to encounter a variety of terrains so footwear needs to be designed for a range of conditions.

Protecting your finds

It's important to spend some time considering the best way to protect your finds onsite, in transit, on display and in storage. Prior to your visit, consider the equipment and accessories you're likely to need, as these will differ depending on the type of rock, terrain and prevailing weather conditions.

When you discover a fossil, examine the surrounding matrix (rock) and consider how best to remove the specimen without breaking it; patience and consideration are key. The aim of extraction is to remove the specimen with some of the matrix attached, as this will provide added protection during transit and future handling; sometimes breaks are unavoidable, but with care you should be able to extract most specimens intact. In the event of breakage, carefully gather all the pieces together, as in most cases repairs can be made at a later time.
