This place is just like Wrens Nest Dudley i.e. Silurian. I like both places but find different things at each. Personally I have found more Trilobites bits at Wrens Nest. 1 - Arachnophyllum murchisoni Coral, top view 2 - Amphistrophia funiculata Brachiopod 3 - Favosites Coral 4 - Halysites Coral 5 - Heliolites Coral 6 - Kodonophyllum truncatum Solitary Coral 7 - Labechia conferta Stromatoporoid sponge 8 - Leptaena depressa Brachiopod 9 - Trepostome Bryozoa

Found in the fill of railroad bed. The nearest cut, a good match to the rock type and carbonate nodules found there, is mapped as the forks formation. This is Ludlow aged turbidite. I have reason to believe that this exact area was not included in the study though. The phyla list includes no corals, but I find them to be abundant. Could be just some clay that got spread into the mix, but it sort of looks like some kind of life form or trace.

These two finds are in one piece of rock found in some roadside rip rap in Kankakee County, Illinois. Based on other fossils I found and knowing what is exposed in quarries nearby, I believe they are from the Silurian Racine Formation. I have never worked with dolomite before, so I would also love to hear any prep advice you have, as well as IDs! The first seems to be a couple of pleura from a Gravicalymene, but is it likely there is more there? The second one has me puzzled- is it a trilobite part, or maybe a brachiopod? It seems like it is symmetrical, but covered by the matrix. Thanks!

Hi, I recently found this in the Wenlockian Sugar Run formation in Illinois. I'm guessing it is a Dalmanites pygidium, but not sure. It has some interesting ornamentation. Any ideas?

Yesterday, I was searching the Arctinurus layer of the Rochester Shale. Gorgeous day in Western New York. Here is the bench I planned on going through. If you look really hard in the middle and halfway down, you can see a Trimerus delphinocephalus. (Just kidding) I don't have X-ray vision and you can't see it because it wasn't exposed yet. A nice complete prone bug was waiting about 420 million years to see daylight again. This is what I first saw looking at me. I take pictures prior to extraction, you never know what can happen. It was sawed out and worked out well. Looks like it will be a quick clean prep with not much gluing. Hope I can post finished pictures in a couple weeks.

If anyone would like to visit Wrens Nest near Birmingham ( in the UK) on a mutually convenient date sometime in the next two months I'm happy organise it. Wrens Nest is Silurian and an incredibly productive site, you WILL go home with LOTS of finds. The hash plates here are spectacular. You may find a trilobite or two too, at least two species can be found there to my knowledge. Common finds are crinoid bits, branchiopods, social corals, bryozoa many in great condition. These look spectacular on hash plates. Pieces of sea bed are easily found with beautiful texture and often have fossils on them. Less common are solitary corals and trilobites. Its a family friendly area even for very young ones with several beautiful walks suitable for youngsters and wheelchair users as well as more demanding walks. Partners/spouses not interested in palaeontology will, I'm sure, enjoy the area. If you're interested can you add your name as a response to this thread and pm me for my email. I'll then send emails back copying in everyone (if anyone wants to come along of course! If not I'll go on my own ) and we can work out a date. Link to to my recent trip report Cheers John

Hello, This appears to be an internal mold/cast of an orthoconic nautiloid, and therefore I am not sure if there is sufficient detail to get an ID. This is from the Niagaran Series, Burnt Bluff Group, Hendricks Dolimite (Fiborn Member) Formation (middle Silurian) of Schoolcraft County, Michigan (Upper Peninsula). Looking for more info on possible identity from those familiar with the Silurian orthocones from this area. @FossilDAWG? Cross section

Today I decided to go and visit a roadcut that I red on one of the Silurian literatures I got my hands on (a big thank you to those that led me to those PDFs relating to the geology of the Niagara Escarpment). It turns out the roadcut on the Niagara Escarpment is near my home which is a pleasant suprise to me, considering that I have been disappointed by the Queenston formation. This roadcut is actually several exposures that run on an access road that can lead one to the upper part of Hamilton, Ontario. Here is the exposure I decided to explore. I chose this exposure as the access is a busy boulevard with cars driving by with no sidewalks and pedestrians. I had several people honk and call out to me as I was exploring the site. Maybe I should have worn a safety vest of some sort? Is that even necessary?

Quick trip to Wrens Nest, Dudley, West Midlands, UK
JohnBrewer posted a topic in Fossil Hunting Trips
Hi rock heads Last weekend I was teaching in London which gave me the opportunity to break the journey up by stopping off 2/3 of the way home to Manchester at Wrens Nest. Wrens Nest is situated in Dudley, a town close to Birmingham in the West Midlands, UK. Wrens Nest is the best and productive Silurian site in the UK. Here's two maps of the location Not often you find a site of this size and quality bang in the middle of a large town! There are are three options for parking, the actual car park (which was locked as a UK public holiday. Or The Caves pub next to Wrens Nest. Or the road. After a two minute walk I was in the national park. No hammers are allowed or needed! Here's the Silurian sea bed. It's cordoned off as there are regular rock slides revealing another layer of sea bed. Cool huh? -
I’m going to try and i.d. these Silurian brachiopods, as this note in the matchbox below that holds them is all the information I have. What I have noticed is those indicated with the “white arrow” below would appear to have the same appearance as each other. But the one indicated by the “red arrow” below looks more bulbous and not flat on the bottom. Does anyone think that there may be two different species here?

Amazing preservation, see closeup images for detail of ornamentation. This near complete specimen is large; about 20 cm in cranial-caudal dimension. At the end of the search, I was sitting in the ATV drinking water, and happen to glance out to the right, when to my shock there was a complete scorpion (Proscorpius Osborni) sitting within easy reach in plain sight!! Mr Lang kept the scorpion in order to try to find the mirror image fossil counterpart, and said he'll let me know if/when he might make it available for sale. I have right of first refusal, at least. On plate I took had both a small Pterygotus claw and the coxa of a giant Pterygotus. 5 cm make sure you click on the image and zoom in to see the detail of the carapace surface -

While walking around the gem show this past weekend, I walked by a booth with a number of fossils. Most were the usual shells of gastropods, brachiopods, corals and fish plates. I did notice this in a box and felt inspired by a past trade with member Malcolmt. An almost complete eurypterid. Labeled: Eurypterus remipes, Silurian- Cedarville, New York. Originally priced at $49.50, I talked her down to $15.00! I'm happy.

When the Eurypterid bearing strata weather and crack conchoidally, two nearly identical fossils are produced when the rock splits through the fossil itself. -
Hi I made my first visit to Wren's Nest yesterday. I still need to go through my finds but did well including some Dudley bugs (partial) and lots of coral and brachiopods. However this partial trilobite had myself and others stumped. If anyone can help with ID and cleaning up I'd be grateful (I don't have any professional prep kit like air abrader or air pen). Trilobite at bottom right of first pic. Thanks! Sam

Hi, Im sorry to be back on this topic again but the suspicion is bothering my way to much after spending even more time looking at this piece and comparing it that resembles a very worn, broken up trilobite head from a possibly large one, the location (New York) I found this in I also found other more clearer trilobites but also a few that are 100%trilobite but worn to point that they nearly blend in right with the rock and have minimal features, my guts bothering the hell out of me so I provided a final set of even better photos below from an angle that I haven't posted on the original thread Hoping for someone to lay me to rest once again and tell me its a rock one more time , the texture though barely visible in the photo makes me believe its something, if not trilobite it doesn't share the same consistency as the surrounding rock and shale in certain areas and upon very close examination has very minimal fractions of pieces with a celluloid trilobitey or living thing texture.

Hey all, I'm obviously new here. My 11yo daughter wants to compete in a fossil finding contest that ends at the end of August, and I need some help finding a good place to look. I don't want to travel far for this effort. Back when I was a kid, I used to find fossil conglomerate rocks at the beach in Port Washington. I would melt down the matrix in sulfuric acid(from old car batteries!) and recover crinoid stem pieced and occasionally a nice brachiopod. The beach has changed much since, and I haven't seen any traces of such rocks recently. We tried poking around Lime Kiln Park with rock hammers, and came out with just a few poor quality castings in limestone. I still have some of those fossils I collected in Port, plus many other fossils that my rockhound grandfather and I dug up in Illinois and South Dakota on rock hunting trips, but I certainly do not want to help her cheat. Any help would be greatly appreciated!

I went to a rock outcropping in Central NY to look for Eurypterid fossils for about 2.5 hours yesterday, and focused on perusing the tailings pile that looked old, hoping for new freeze-thaw fracture planes through old discards might reveal previously hidden fossils. My finds were scattered partial specimens; I also collected 10 samples of the Bertie Waterlime (is the new term for Waterlime Dolomite or Dolostone?) with probable remains that were mostly hidden for purposes of experimenting with artificial freezing and thawing to try to uncover the fossils within. I will report on those experiments at some point in the future, as I hope to try a couple of approaches and document the results to see what will maximize recovery of the fossils. It was somewhat in shade in the afternoon hours--it would be exposed in sun during the morning, so bring sunscreen. It was cloudy when I took this picture. 2 cm 2-3 cm 2cm About 2.5 cm transverse
