  1. Disorganized chaos

    Well I got a new phone (Samsung Galaxy Note 8) on Black Friday and was playing with it snapping some pictures. Those of you that have been to my house know that I am totally disorganized and definitely need to organize my fossils. Thought I would share some of the disorganized chaos that is my basement fossil dumping area. This tends to be where fossils go to rest if they do not make it to the glass display cases (3) upstairs where I put the good stuff. But then that is a step up from the ones that never get out of the map drawers and boxes in the garage. One of these days I will get around to organizing things, just never happens to be today....... I suspect my kids will end up having to organize it someday......... (That's a scary thought)
  2. From the album MY FOSSIL Collection - Dpaul7

    Emmonsia Coral, a Colony Coral SITE LOCATION: Beachriver Formation of the Brownsport Formation along Hwy. 641 in Decatur Co., Tennessee TIME PERIOD: Silurian Period (ca 430 mission years old) Favositida is an extinct suborder of prehistoric corals in the order Tabulata. The tabulate corals, forming the order Tabulata, are an extinct form of coral. They are almost always colonial, forming colonies of individual hexagonal cells known as corallites defined by a skeleton of calcite, similar in appearance to a honeycomb. Adjacent cells are joined by small pores. Their distinguishing feature is their well-developed horizontal internal partitions (tabulae) within each cell, but reduced or absent vertical internal partitions (septae). They are usually smaller than rugose corals, but vary considerably in shape, from flat to conical to spherical. Around 300 species have been described. Among the most common tabulate corals in the fossil record are Aulopora, Favosites, Halysites, Heliolites, Pleurodictyum, Sarcinula and Syringopora. Tabulate corals with massive skeletons often contain endobiotic symbionts, such as cornulitids and Chaetosalpinx. Like rugose corals, they lived entirely during the Paleozoic, being found from the Ordovician to the Permian. With Stromatoporoidea and rugose corals, the tabulate corals are characteristic of the shallow waters of the Silurian and Devonian. Sea levels rose in the Devonian, and tabulate corals became much less common. They finally became extinct in the Permian–Triassic extinction event. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: †Tabulata Family: †Favositidae Genus: †Emmonsia

  4. Another trip to Wrens Nest

    Had a great day out with Candace and Nick @thelivingdead531 @Barerootbonsai Friday 20th. Here are a few of my finds, I’ll post the hash plates when I’ve photographed them. We all got a great variety of finds, here are some of mine. I’m sure Nick and Candace will add to this thread.
  5. One of a number of spiral monograptids from this period and a zone species, these have all been referred to Monograptus at various times as well as separate genera based on rhabdosome form which may not be of significant importance. It is bisected by an unidentified straight Monograptus. Reference for ID (as Monograptus spiralis): Elles & Wood 1901-1918, Monograph on British Graptolites, Pal. Soc. Monograph 33. (Plate XLVIII, fig. 7). Now generally referred to Oktavites Levina, 1928, e.g. in J. A. Zalasiewicz, L. Taylor et al 2009, Graptolites in British Stratigraphy, Geol Mag. 146, pp. 785-850.

  6. Wenlock Edge, Shropshire, England

    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
  7. This anything 2

    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.
  8. Silurian Trilobite Pieces?

    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!

  10. Silurian trilobite

    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?
  11. 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.
  12. 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
  13. Silurian Orthoconic Nautiloid

    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
  14. Roadcut in Hamilton

    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?
  15. 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?
  16. Odd shape Lampshell

    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?

  17. 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
  18. The Scorpion's Sting

    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.
  19. From the album Eurypterid Fossils

    When the Eurypterid bearing strata weather and crack conchoidally, two nearly identical fossils are produced when the rock splits through the fossil itself.
  20. Wren's Nest unusual trilobite

    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
  21. Coxa of giant Pterygotus

    From the album Eurypterid Fossils

    5-6 cm transverse. Moistened and digital image tweaked to increase detail.
