  1. 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
  2. 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.
  3. 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.
  4. 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
  5. Coxa of giant Pterygotus

    From the album Eurypterid Fossils

    5-6 cm transverse. Moistened and digital image tweaked to increase detail.
  6. 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.
  7. 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!
  8. 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

  10. Fossil Hunting in Hamilton?

    Hi guys Im thinking of fossil hunting at some of Hamilton, Ontario waterfall areas like Albion Falls and Webster's Falls and does anyone have any pdf papers relating to the geology of the area? I heard there are various Silurian formations that can be found at Hamilton.
  11. Eurypterid hunt in NY

    My daughters and I went on what I thought would be a once in a lifetime hunt for Eurypterids over Memorial Day weekend this year. I wanted to share the bounty...18cm long 20 cm closeup of telson cool to get dorsal and ventral aspects of the prosoma, thanks to the plane of the conchoidal fracture
  12. Hey guys, need help on Silurian id

    My wife and I have been hunting a Silurian Dolomite outcropping all day in kentucky. We found about 30 beautiful trilobites. In the rock, we also found several of these things. I imagine it is cnidarian something or other, but can't place exactly the id. Any help would be appreciated. -J

    Hey guys, I'm in bardstown right now, and I'm looking for some trilobite road cuts!!! Any help would be appreciated!!!! You can text me at 813-514-7730
  14. I will be in Western NY on Sunday and Monday this coming weekend, and would like some recommendations for sites to visit. I will be travelling from NY City to Canandaigua, and am willing to stop on the way if there is an interesting trilobite collecting site--I am flexible on which way I drive, etc. Since lagerstatten sites such as Walcott Rust are not open to the public, I would love recommendations to sites that are known to be accessible, public or private. If private, please PM me if you think the property owner would be amenable to a request from a solo collector. Specific directions to any recommended site are very appreciated. I am also happy to meet anyone along the way so I can learn with someone with experience. I am interested in trilobite collecting, and would love the chance to find the unusual or less usual species, so the site can be Ordovician, Silurian, or Devonian. Places that you know have better preservation are preferred, even if it is more difficult or farther to travel there. Off the beaten track is fine, as long as it doesn't take a long time hiking just to get there, or is very physically strenuous to reach. I will be making a stop at Penn-Dixie, where I am a member. I will also be staying on my family's property in Canandaigua that has a creek with trilobite species (see images of trilos collected in May this year). Unfortunately, both of these trilobites I have below were found out of their stratigraphic context so I was wondering of there is any resource you can refer me to that can help me tell which strata are probable for finding trilobites(ie as I walk up the creek, and look at the exposed strata, is there a way to visually recognize each bed in the formation?). On the paleodb.org maps, the trilobites listed on the east and west shore creeks of Canandaigua Lake are Phacops/Eldregeops and Greenops sp of the Hamilton Group, Moscow and Jaycox Formations. BTW, I gave up on trying to remove matrix on this one, too hard to do in control--I have no pneumatic tools, only a pick and a small hammer. The Penn Dixie matrix is sooo forgiving/easy in comparison! Thanks in advance!
  15. Hello everyone! I need your help on identifying this piece. This could possibly be a fossil because of the three plant fiber-like impressions on this small sedimentary stone. My sister found it while we were walking on a trail in Wolverine campground park in Genesee County, Michigan. If this is a fossil, then I think that these are fossil impressions of plant material. The geologic strata in Michigan ranges from the Ordovician up to the Pennsylvanian period. I've checked where Genesee county is on the Michigan geologic map, and the bedrock is of Pennsylvanian. Let me know what you think these impressions are from, thanks.

  17. More of a reccy really

    As the title says, more of a reccy for later in the year when I hope to meet Nick @Barerootbonsai again for a hunt. I went away to shoot several images for a cd cover/book for a quirky band http://ironbootscrapers.com/ using one of the Victorian methods of photography I practice. On the journey back back I decided to spend an hour at Wren's Nest in Dudley, West Midlands, UK https://en.m.wikipedia.org/wiki/Wren's_Nest Wren's Nest is a productive Silurian site, particularly for corals such as favosites and rugosa. Here's a fine looking chap at the site
  18. wenlock edge advice

    hi guys i'm planning to go again in wenlock edge next thursday for some hours of hunting, not like the last time that i went for just 2h. Anyone can suggest the most productive path to follow? any advice wil be appreciated. thanks
  19. The Mysterious Cheirurus

    The fossil(s) in question here were collected during the summer of 2016 from the Liston Creek Limestone (Silurian) in northern Indiana. I am using them for my senior thesis project in which I'll be comparing Ordovician trilobites with Silurian Trilobites. Anyways, I have been taking a scientific illustration class during the month of May and for my final project I decided to do a stippled illustration of one of the Cheirurus cephalons I collected in 2016 (in total i have about 7 cephalons of varying sizes, all with identical morphological characteristics). I've been trying to narrow this particular specimen down to the species level since I plan include the binomial nomenclature on my final illustration. After a days worth of researching I'm still unable to confidently identify the specimen at the species level. The literature I have on the rock formation this specimen comes from lists Cheirurus niagarensis among the common fauna. From what I've seen online, I don't think my specimen is C. niagarensis. Two other possibilities I've noted are; C. infensus, and C. insignis... So far those are the only 3 Cheirurus species that resemble my specimen the closest, but I'm still not confident in any one of them in particular. As fossil ID information is notoriously hard to find on the internet I've decided to post some pics of my specimen on here to see if anyone can help me to ID it. The first 5 pics are of the specimen I'm using for my illustration. The 6th picture is of the previously mentioned specimen (right) and a larger specimen (left).
