FOSSIL HUNT - Upper Gilwern Quarry, WalesSaturday, July 29, 2017 from 11:00 AM to 4:00 PM (BST) More Information →
On the edge of the Brecon Beacons, Upper Gilwern Hill is a site long known for its well-preserved and complete trilobites. The hill is made up of rocks from the Lower and Middle Ordovician, and the privately owned quarry is accessible to parties on request. The trilobite fossils here are plentiful and the chances of ﬁnding a good number is very high.
* Suitable for Adults only
* LEADERS: Andrew Bayliss and Lee-anne Colins
* HARD HATS (No Cycle Helmets), and HIGH VISIBILITY VESTS or jacket essential.
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.
Fossil guide to this location: https://ukfossils.co.uk/2016/06/02/upper-gilwern-quarry/
Many fossils can be found on the scree surface, but the use of a geological hammer and a bolster chisel to split the shale along the bedding plane will reveal many and often complete specimens. Safety goggles are essential. The sheer number of trilobite fossils indicates a rapid burial and death, probably from hot, burning ash raining down from sub-aerial volcanoes, followed by poisoning from noxious fumes.
The fauna here is dominated by the large asaphid trilobite, Ogyginus cordensis. Other common trilobites are the trinucleids, Bettonolithus chamberlaini and Trinucleus abruptus, as well as the rarer, Anebolithus simplicior. Other fossils include orthocones, sponges, brachiopods and graptolites.
Can I book over the phone?
Yes, you can, and we can take card payment, however a waiver must be signed before we can accept your booking. The waiver can be emailed or posted out, but must be returned within one week of the booking. Contact us on: 01502 725205 (Mon-Fri 8am-3pm).
Can I pay on the day?
Sorry, we do not allow anyone to pay on the day, as we cannot provide pre-preparation details on risk assessment, and due to health and safety, places are limited.
Do I have to bring my printed ticket to the event?
This will greatly help us and speed things up, but leaders will have a list of those attending on the day.
Is my registration ticket transferrable?
Please contact us and we normally try to accommodate this.
I have a question not listed?
Please contact us on 01502 725205 (Mon-Fri 8am-3pm).
What happens if I can’t make it on time or get to the venue?
You need to contact us urgently. If this is within a few days of the event, call us on 01502 725205 (Mon-Fri 8am till 4pm), if it is on the day or a couple of days before, contact the leader in the final confirmation email detailing where to meet and times. We cannot guarenete we can wait for you, but where possible, we will try.
Are toilets nearby?
Most events will not have access to toliets. 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 toliets are close by, but it is best to presume they wont be available.
Will my friend's hammer and chisels from their tool box be okay to bring?
No, standard tools are made from inferior metal which splinter very easily against rocks. This is both dangerous to yourself and others, and flying metal can cause eye injuries or penetrate the skin. ONLY hammers specifically made for geological use can be used. We offer some to add to your order if you dont have any.
What happens if the event is cancelled?
We try very hard to avoid having to cancel, but if an event needs to be cancelled due to adverse weather conditons or unforeseen circansances, we will notify you immediately, and you will be offered an alternative hunt or date or a refund.
