Cayton Bay yields ammonites and some superb gastropods, bivalves and brachiopods from the Oxford Clay. These are best found on extreme low tides on the foreshore.
* Suitable for children 5+ (All children must be acompanied by a paying adult).
* HARD HATS (No Cycle Helmets), and HIGH VISIBILITY VESTS or jacket essential. We do not provide these, but you can add these when ordering if needed.
Most of the year, the best beds are often covered with sand. However, the Cayton Clay provides the best chance to find a variety of fossils by simply searching along the foreshore. Its fossils include belemnites, ammonites and other molluscs.
Near the waterworks at the south end of the bay and at low tide, calcareous sandstone (from the Hackness Rock Member) is sometimes exposed, which yields a range of fossils including bivalves, brachiopods, gastropods and ammonites (Cardioceras and Peltoceras). However, the most productive beds at Cayton Bay are the Oxford Clay. Sadly, these are often covered up with the slipped upper Cayton Clay formations or covered with sand.
If you are lucky enough to visit during scouring conditions, the Oxford Clay can be seen on the foreshore. At the north end of the bay, keep a look out for nodules, as some of these contain shrimps (Meyeria and Macrocephalites kamptus). The Oxford Clay is packed with bivalves and gastropods, and can sometimes be found in the lower cliff sequences
We try to keep most events to a 11am till 4pm schedule, but final times may vary depending on tide times and working around quarries. We will always advice start time and where to meet well in advance of the event.
Please note, many of our locations will not have toilet facilities, water, or other amenities.

The Wren’s Nest National Nature Reserve is world famous for its huge variety of Silurian fossils. Indeed, the town of Dudley has adopted a trilobite as part of its coat of arms – the trilobite, Calymene blumenbachi, was so commonly found by miners in Victorian times that they gave it the nick-name “the Dudley bug”.
Over 700 diﬀerent types of fossil can be found here; 186 fossil species of which were ﬁrst discovered and described here and 86 are found nowhere else on earth. Wren’s Nest contains the most diverse and abundant fossil fauna found in the British Isles and the fossils are among the most perfectly preserved Silurian fossils in the world. Despite the frequency of visitors at Wren’s Nest, the constantly eroding rocks and build up of scree allows safe and productive fossil collecting. The site is ideal for children, although there are no toilet facilities within the site.
At Wren’s Nest, there are so many fossils to collect that you will easily ﬁnd something to take home with you. Take your time and look at the loose material on the ground. Remember do not use hammers or other tools on the rock faces. Hammers are totally banned from this site, in any case.
Fossils to be found include trilobites (especially Calymene blumenbachii-‐ the ‘Dudley bug’), crinoids, brachiopods (some of the easiest fossils to ﬁnd on Wren’s Nest are brachiopods, such as Atrypa, Strophonella and Leptaena), corals, sponges, bryozoans, gastropods, bivalves (especially Goniophora and Pteronitella), criconarids, nautiloids a superb example of a Silurian reef ecosystem.

Are toilets nearby?
Most events will not have access to toilets. The best places to find fossils are mostly areas away from built up areas, and tend to be quite remote. There are a few exceptions where toilets are close by, but it is best to presume they won’t be available.
Will my friend’s hammer and chisels from their tool box be okay to bring?
No tools are allowed on this site due it’s designation as a SSSI, and in any case, are not needed as fossils can be found loose in the scree.
