White Park Bay

Ten kilometres northwest of Ballycastle in Co. Antrim is White Park Bay. Successive layers of rock yield Mesozoic fossils including ammonites, belemnites and Gryphaea. However, the cliffs and platforms are protected, but many loose blocks containing fossils and some washed out fossils can be found. The beach is also known as one of the few places in the world to have “singing sand” – when conditions are right, the extremely fine sand vibrates to make a humming noise. The location is also known as a historic manufacturing hub for flint axes and arrow heads, due to the abundance of flint nodules found in the cliffs, with artefacts dating back as far as 8,000 BC. The landscape also features passage tombs looking out over the sea, where, on a clear day, the coast of Scotland can be seen.Cretaceous, Jurassic, Foreshore, Rating: ♦♦♦

How Fossils Formed (TAPHONOMY)

The most common method of how fossils formed is once an animal or plant dies, it falls to the ground, and is covered by sediment. This is often sediments brought from water. Of the vast amount of prehistoric life that died, it is only a tiny amount that has survived the fossilisation process. The conditions when the majority of life died were just not right at that time, to preserve them.

Where to find fossils

Fossils can be found in many places, most fossils are found on the beach or in quarries but many have been found in some very unusual places. Below is a list of places that you could find fossils. Please note some places such as quarries and farm fields need permission before you can enter, other places where fossils form part of the construction such as sea defences and walls, should not even be attempted. Damaging other peoples property is not only illegal, but morally wrong.

What is a fossil?

The word Fossil used to be defined as ‘something dug up’. Now-a-days it generally means ‘The remains or trace evidence of prehistoric life’. The study of fossils is called palaeontology; someone who collects and studies them is called a palaeontologists. Fossils can be as tiny as a grain of pollen or a seed for e.g. or as huge as a limb bone from a giant dinosaur. For animal or plant remains to have become ‘fossilised ‘, they must go through a certain process that preserves them for up to millions of years after they have died. Usually it is only the hard parts of plants and animals that survive this long process.

Seaham

Seaham is a Carboniferous coal measure spoil heap, which was dumped in front of magnesium limestone cliffs at the old Dawdon Colliery. The reserves are so extensive that they have provided years of interesting collecting from spoil, which is gradually being washed by the sea. The colliery closed in 1991, but the tall cliffs of spoil continue to yield well-preserved plants. Carboniferous, Spoil, Cliffs, Foreshore, Rating: ♦♦♦♦♦

Sudbourne Park

There are two classic pits within Sudbourne Park. Both have become very overgrown in recent years, but sections are cleared from time to time to keep these SSSIs accessible and available for further research. Rich shell beds of Coralline Crag yield a variety of fossils, which can be easily collected from when sections are cleared. Pliocene, Spoil Heap and Disused Pit, Rating: ♦♦♦

Equipment Guide

When fossil collecting, you will need the correct equipment. Often, each location will differ and of course depending on the weather and time of the year, you will also need to consider the correct clothing.If you are collecting in a quarry, there are important health and safety requirements by law. These are that you must wear a hard-hat, high visibility jacket and steel-toe-cap boots. This guide explains the recommended equipment you should take, both for your own safety and also the tools you might need.

Abereiddy Bay

Abereiddy is the best and easiest place in the UK to find graptolites. It is also an outstanding place where you can see and photograph in situ graptolites, crammed into the sloping bedrocks. Although this site is a SSSI (so hammering the bedrock is strictly prohibited), there is no reason why you would want to disturb the bedrock. The foreshore is full of rocks that can be picked up without tools and contain better specimens than those in the bedrock. Ordovician, Cliffs and Foreshore, Rating: ♦♦♦♦♦

Houghton Quarry

Houghton Quarry is an abandoned quarry, formerly used to extract chalk for a cement works onsite (which is no longer there). Quarrying stopped about 40 years ago, but, due to its size and terracing, only parts are overgrown, leaving an enormous amount of clean chalk. A large amount of this consists of boulders of various sizes on the quarry floor, yielding many good fossils. Collecting is not allowed here. Cretaceous, Disused Quarry, Rating: ♦♦♦♦

Tilton-on-the-Hill

This site is a disused railway cutting near Tilton-on-the-Hill, which is extremely rich in fossils. Now fairly overgrown, there is just one small area of collecting where the cliffs are still accessible. The site is a SSSI, for the diversity of its fossils, its geological important and for the living fauna and flora that can be seen here. It is also a nature reserve. One key feature is the presence of two thick limestone beds – crammed full of brachiopods – which can be easily collected from by looking in the loose scree.

Gedgrave

The cliffs at Gedgrave, which run along the east bank of the River Butley, were previously completely overgrown for quite a number of years, despite being recognised as an SSSI for their geological and palaeontological importance. However, as part of Natural England’s conservation of SSSI sites, a small, three metre section has been fully excavated making this site accessible once again. Pliocene, Cliffs, Rating: ♦♦♦

Bach Y Graig

Bach Y Graig is a stream section, rich in trilobites and graptolites. The latter are mostly complete, but are also very fragile and paper thin. Therefore, when splitting, their segments often end up being separated on either side of the split. The site is also dark, being in a thickly wooded area, and is very hard to find without a map or GPS. Ordovician, Stream, Rating: ♦♦♦

Craig-Y-Fro

This disused quarry is situated along the main A470 through the Brecon Beacons. The quarry also contains a waterfall, which keeps the faces clean. There is strictly a no hammering allowed, due to SSSI rules and because the site falls within the Brecon Beacons National Park. However, loose material can be collected from, especially at the base of the waterfall and from the stream running through the quarry. Devonian, Disused Quarry, Rating: ♦♦

Tites Point

The actual site is a foreshore location on the eastern shore of the River Severn to the west of Tites Point, in Gloucestershire. At low tide, the Silurian Ludlow beds are exposed, yielding a range of fossils, including seeds, plants and molluscs. However, of most importance is the abundance of fish remains from the Ludlow Fish Bed. Silurian, Foreshore, Rating: ♦♦♦♦

Cogenhoe

To the southwest of Cogenhoe is an extremely overgrown quarry on the top of a hill. Although the quarry itself has now become too overgrown to collect from, the public footpath, which takes you to the quarry, climbs through several different geological formations and rocks are scattered across the fields next to the footpaths. Ploughing uncovers the rocks; and it is in them that you can find fossils. Jurassic, Ploughed Fields, Rating: ♦♦
