  1. Iowa trip

    Just thought I'd share some finds from a club trip to the Devonian of Iowa last Sunday. It was a good trip. A nice clam. This Greenops disintegrated shortly after exposure. Crassiproetus sp. Before After. Enrolled Greenops sp. and Eldredgeops noorwoodensis Group shot
  2. This may seem like an obvious question but I’ve always wondered what specific structural differences are present between a Greenops and a Bellacartwrightia. Any help would be appreciated!
  3. Hello forum folks I went to DSR again yesterday 10/05/19 as I had another free day to go collecting. I may not being able to fossil hunt until the end of the month so I had to take advantage! I have been noticing the phyllocarids are coming from certain intervals lower in the quarry...could be nothing....could be somthing....before I assumed I figured I should test it. I knew the exact bedding plane my last Echinocaris came from so I planned on opening a shelf on that bedding plane. My thought was if I could find another phyllocarid on that bedding plane maybe it could mean something....clearly not enough data to make any final assumptions but heck who wouldn’t dig a bedding plane that has produced lol. I was still specifically upset I couldn’t find the missing piece to my phyllocarid from last trip so I did some scanning I initially. I knew it was a waste so I got to work on the bedding plane I desired. before I got started I moved a lot of over burden and got some nice slabs moving. Loving the wedge and sledge combo....so much easier on my body physically. anyway....I found this Echinocaris punctata about 30 minutes into clearing off the shelf. Same bedding plane!!! Only about 1-2 feet from the one I found last trip. Bingo!! I’m going to show a few close ups...this is a really interesting specimen. It appears to be A double carapace folded in half. You can see the margins of the other half and some spots actually fold over slightly that confirm this. It would be great to reveal the other side but I would have a very thin, flattened, fragil specimen. also.....I’m feeling like the boy who cried wolf here but are these mandibles I see on the top left part of the specimen (Seen below)? The margins aren’t as easy to see but it’s clear there are some type or serrations on each part. Here is a close up that does a decent job showing what I’m talking about. They are really non photogenic because of the rust on the shale between the mandibles. It messes with the margins visually. It was still really messy with debris/rubble when I found it so I wasn’t sure where the counterpart was under the rubble. Foolishly it’s on a slab I left behind and I’m going to try and rush out after work to grab it this week. I found this another foot away from the phyllocarid above. When I found this I immediately thought I had a rhinocaris phyllocarid but now I’m not so sure? Unless someone can say for sure. Just doesn’t look right. here is a close up.....it has some lines running across it that make me question what this is. So for now I’m not sure. I found this Rhinocaris sitting out in the open so I have no idea what layer it came from. I’m positive this is a Rhinocaris and it’s very different from the other unknown specimen I found. Here is a reference photo for people who are unsure what phyllocarids are. I really think this specimen is special like the one I found last trip. Also, I do find it interesting that this was on the same bedding plane and very close to the last Echinocaris phyllocarid. More field work will help tell the tale. More to come....my trilobite finds from DSR and I found a layer with all Eldredgeops!!! Really awesome. Stay tuned for part 2
  4. Penn Dixie Greenops

    Decided to tackle prepping this greenops today that I found at Penn Dixie a few weeks back. Part of the cephalon broke off in the negative, but the glue job worked OK. There is still some digging needed to expose the right cheek and pleural tips but they should (hopefully) be there. A fold along that side buried them deep in the matrix. Not a perfect bug but my best greenops found so far
  5. Quick trip to DSR

    Hey all, My sister had a friend in town and it was my turn to come up with an activity, so naturally I took them out fossil hunting! I picked DSR since there is a 100% guarantee that everyone who looks will find something. I spent most of the time there ripping up slabs for my sister and her friend to split down. Unfortunately a thunderstorm rolled in and we had to leave early, so there is a sizeable pile of fresh material waiting for whomever gets there next. The girls found some good stuff- brachs, crinoids, and a few dipleura & greenops cephalons. I had the lucky find of the day with a decently sized, albeit disarticulated, dipleura. I think the whole thing is there, but it will take some prep to find out for sure.
  6. Greenops from Hungry Hollow

    Hello again! I have one more ID request (for now ). I received this Greenops as a gift, but I think I deleted the email which stated the exact location/formation information - does anyone recognize the matrix that it's on? And is it G. widderensis or is it G. arkonensis? I have a document stating that these two species have been found at Hungry Hollow (near Arkona, Ontario, Canada; mid-Devonian in age) - are there two different Greenops species found at Hungry Hollow or only one (widderensis)? Thanks so much! Monica I'll tag @Kane and @middevonian for this one
  7. I found this small pygidium while prepping some Penn Dixie material. Not sure whether it’s Greenops or Bellacartwrightia. Any thoughts? @Fossil-Hound @DevonianDigger Hope you don’t mind the tags.
  8. Trilobite larvae? (Update: SEM Images)

    I found some unusual structures under the exoskeleton of this Greenops (Middle Devonian) They are auburn brown and somewhat translucent, reminiscent of the material that makes up the exoskeleton of the adult. I only found them concentrated in the area where the exoskeleton of the trilobite came free of the matrix. They are embedded in the matrix there. I did not find any outside of this area in the surrounding matrix. There are a total of 6 of them that are exposed. They are not ostracods. They could be spores, I guess. They could be lots of things, and their concentration within the trilobite could be entirely coincidental. But, Looooooong shot... could they be trilobite larvae? @piranha Below: General location of the objects. Scale in mm. Below: Several of the objects exposed in different positions. Scale in mm (the objects are about 0.25 mm in diameter). This is the best I can do with a dissecting scope. Only other option, if warranted, is SEM (which I can do if necessary).
  9. Removed from a stream boulder, this Greenops like pygidium is larger than most complete Devonian trilobites from NY. Im not sure to what the exact species is so Im just calling it Greenops like. The age is Middle Devonian from Livingston County, New York. This could have been a near 5 inch bug if complete. Based on the dimensions of the largest complete Greenops sp. I have found in the collected area. From near spine tip to spine tip wide - 2.3" (58.50mm) Around 1.6" - 1.7" long (42mm)
  10. 4/7/19

    Great day today. Ended up getting a greenops some eldredgeops rollers some really nice brachiopods and even some carbonized wood. What was really awesome is I ended up finding 4 large ammonites out of the Wanakah shale which was strange. But hey I’m not complaining.
  11. Greenops barberi

  12. Hello everyone, When I joined the forum I shared a few of my Buffalo, New York trilobites but only my rare Pseudodechenella rowi trilobites. I said I was eventually share some other trilobites so here I am haha. The winter has kinda been a bummer recently in upstate New York but we just had a freak warm day recently. In the future I want to share my Eldredgeops collection, brachs, cephalopods, plant specimens but I’m not going to rush it. In this post I’m going to share some of my Greenops sp. that I have collected exclusively from the wanakah shale on the Lake Erie shore south of Buffalo, New York. I think I may have an example of Greenops barberi and Greenops grabaui in my collection but I guess I’m not 100% confident in the ID. These 4 are probably my best specimens I’ve managed. For reasons most likely related to environment they are not common and they do not like to preserve well. I would consider them pretty rare actually. Ill follow up with a few more photos of some “lower shelf” specimens I’ve found lol.
  13. My Trilobite Drawings

    Taking a break from grading essays, I gave the pencil another go. This is a prone Greenops. The shading is not as crisp in gradation as it could have been, but I was only using an HB pencil. I did get the pustules and eye lenses on it, which gives it a bit of texture.
  14. Hello everyone, I kept these from fossil hunts in buffalo years ago cause I knew they were different. I read they split Greenops boothi into 4 different species with 2 variations of Greenops and 2 variations of Bellacartwrightia in 1997. I have some pieces that I’m not really sure which trilobite I’m dealing with. I just know it’s not the Greenops grabaui variety. The cephalon came from basic Wanakah shale that surrounds the “trilo beds” as I was moving blocks. The pygidiums came from the “trilo beds” of the lower Wanakah shale at the Lake Erie shore in Buffalo, New York. I only have “a field guide to Devonian paleontology” by Karl Wilson and “Geology of 18 mile creek” by Grabau for reference. I can’t find anything reliable on the internet either so I’m curious if the kind folks on the forum have an opinion. I do have another book on Devonian paleontology of New York coming in the mail that is more recent but the new paper was written in 1997 and this book is a 1994 book so it may not have the update either. The last 2 pics are comparisons of the pygidium of a Greenops grabaui with the specimens in question to show you why I think they are different. I also just added a last photo of the other side of one of my unsure specimens that’s actually a full trilo but damaged beyond belief...may not help with the ID but maybe it could lol. Thanks Al
  15. Not the best greenops ever

    About a month ago I went to Penn with two fossil buddies and they both found prone greenops. Sadly I did not find one. However both of these greenops were split between the positive and negative and probably were missing some skin as the material was quite flaky. For one of my friends this was his first ever find of a prone greenops. Prone greenops that are nicely laid out are a very rare find in the Windom shale. Most of the ones I have found from there or others that I have prepped for people are fully, partially enrolled or distorted. So to my fossil buddy this was a bit of a special find. We wrapped up the two pieces in tin foil in the field and I agreed to take it with me and prep it for him. Well zoom ahead a month in time and I am going out with him last week to collect and he asks how is his greenops coming, whereby I realize that I have not only not started it ,but in my senility had forgotten I had it and had no clue where it was. Well when I got home it turns out that I had never unpacked the bucket of fossils from that trip and low and behold his fossil was packed just as we had left it. A careful look at both parts under the scope confirmed my opinion that the bug was in pretty rough shape , but a prone greenops, not to mention perhaps his first ever prone warranted we attempt to bring it back to life. Unfortunately I did not take any pics until a ways into the prep but here is what I did to start. 1. Washed the mud off both plates scrubbing with a tooth brush 2. Squared up what would become the fossil plate with the diamond gas saw 3. Cut out as small as possible a square from the top piece of the matrix that contained the top part of the greenops using my 7 inch tile saw with diamond blade 4. On a belt sander using aluminum oxide 120 grit thinned the top piece as much as safely possible to help minimize my prep time later. 5. Using super thin cyanoacrylate glue reattached the top portion to the main slab clamping tightly with a c-clamp. Asusual all prep was done under a zoom scope at 10x to 20x magnification using a Comco abrasion unit and in this case a German Pferd MST 31 scribe exclusively.. Not a lot of scribing was done other than to outline the bug as the skin was not in great shape. Abrasion was pretty much done with a .18 and .10 nozzle using 40 micron previously used dolomite at 30 PSI. Here is the bug after about an our of prepping . I have outlined in red where you can still see the outline of the section that was glued down. A lot of people do not realize that many of the fantastic trilobites you see on the market have actually been glued back together because the splits are often through the bug. I once did a Moroccan trilobite that was in 7 pieces when I received it Here is the bug after another 40 minutes Took some pictures of the prep but frankly they ended up too blurry to use so here is the prep after abrasion is complete and after I have repaired a lot of the parts that broke of in the split. I tend to use a white repair material and always take a picture to let the owner know what has been repaired Here is the bug after coloration applied . The repairs were allowed to cure overnight before coloration and a bit of extra carving to clean up spots.Just waiting for me to do a final cleanup tomorrow after everything has cured a bit more. A long way from being the worlds most pristine or perfect bug but I am relatively pleased that we were able to breath some new life into an ailing bug. Totally prep time about 3 1/2 hours over 4 days. I suspect the owner will be pleased with the result. I have seen people toss bugs in the field that were in this type of shape. For those of you who just need to know the bug is 27mm x 18 mm A slightly different view
  16. Greenops with a hitchiker ?

    The high axial lobe of this pygidium reminds me of the Greenops. Should I put it in that collection camp ? Also, he has a little hitchiker riding piggyback. I assume it is an Eldredgeops that's been a bit distorted. Or is it something different ? Cheers,
  17. You know I am very fortunate to be able to collect in a lot of special places and with a lot of great fossil friends. Over the years I have had the good fortune to meet many of you and even prep a few fossils for some of you that are patient enough and brave enough to trust your gem to what is for the first time a stranger. Arkona, Bowmanville , Brechin, Ridgemount are all special places that I collect....... but equally special is New York States very own Penn Dixie Fossil Park. A real gem. Now some of you might think that Penn Dixie is not for the serious collector ......... but you would be dead wrong. Just ask a few of our Forum Members that came away with exquisite and mighty rare Bellcartwrightia from there last season. I was fortunate to be able to prep a few of them . I even found one earlier this season myself but alas as my post on the forum showed it turned out to be a less than stellar partial but none the less the only one in my collection. Well I was at Penn twice in the last week and a half, once to get in Jay's (Devonian Digger) way as he was getting the area ready for the upcoming "Dig With The Experts". Both times I went with Greg from the forum here. He is my designated driver it seems so far this year.......(Dave you may have been replaced).. You see I have this phobia and cannot drive over large bridges. Well anyway back to the story....... Since I spent so much time helping Jay (getting in his way) on the Friday I needed to go back this Sunday to actually look seriously for some fossils. Kane from the forum as you can see from his posts was there later on the Friday afternoon just as we were finishing up with the excavator. For some reason only my cart and saw ended up in any of his pictures. I The Friday was a reasonable day as I came away with about 15 complete eldredgeops and a so so bug that will be either a greenops or a bellacartwrightia once I get around to prepping it. Greg and I had a pretty good day on this past Sunday. I came away with probably 20 to 25 complete trilobites and Greg seemed to have a fair amount in his bucket but only asked me to cut out one large prone Eldredgeops for him. Anyway on to the topic at hand . ... Since greenops and bella's at Penn seem to occur in clusters On Sunday I went to the area I found the greenops on the Friday and I found what looked to be a promising Greenops. Both were in the first inch of the Smoke Creek (no Jay I will not tell you exactly where). For those of you going to "The Dig WIth The Experts" there is plenty of this material that has been piled up for you in an area that is off limits till the 19th of May. Jay and I did take a walk about the piles and we can see that the material for this year'd dig looks to be excellent. We both saw complete trilobites, brachs and cepholapods waiting to be removed from the rock. I must say we were both very good and made sure that no one (especially Kane) collected from the out of bounds area. So here is the promising Greenops that I found on Sunday as collected, prior to any preparation. I did not get a picture in the field but as is typical of how I collect ( I am an excavator) it was in a 200 plus pound slab that I removed from a bench that I was excavating. Don't look like much.... obviously the eye is less than perfect........ but looks can be deceiving.. Here it is again after a couple minutes of prep... After 1/2 hour it is actually starting to look like a fossil albeit a compressed , twisted and somewhat deformed one... but that gives it character Prep is being done on a COMCO MB1000 at about 50 PSI using 40 micron dolomite. using .015, .018, .025 and .030 Comco nozzles . All work is being done under an Olympus zoom scope at 7x to about 20x magnification Scribe work on this bug is with a British Sealy for the rough work an American ARO for general work and a German Pferd MST31 for the fine work. A real mishmash of nationalities.... Progress continues... At this point definitely thinking that it is a greenops (not a bella) and that it has some potential even though I can see it has eye problems But what is this... is that another bug I see coming into view.... could it be a 2nd Greenops... that had been completely hidden We like hidden bugs as they have the greatest potential to be pristine... nice genal spine poking out of the matrix... probably means the whole cephalon is there Definitely looking like there might be two (which I believe is pretty rare for Penn Dixie).... We find lots of pygidiums but rarely multiple complete greenops on the same plate... Anyway fingers crossed at this point... After a bit more prep work...actually a lot more........ OH No !!!!!!!!!! the second one is inverted ... what a shame.. But what is that under the first greenops.... Oh my goodness its an enrolled large Edgredgeops......... Wait a minute ..... What an I thinking.... no reason to be upset,,,,,I can fix that ..... who says an inverted trilobite has to stay inverted.... Lets just do some prep magic and see what happens.... As you can see the second greenops was flipped in the same location on the matrix. Absolutely pristine killer eyes..... So here is the plate as it currently stands. I still need to make a level base for it once I decide exactly what orientation that I want to present it in. I need to do a final clean at high magnification with a .010 nozzle and low 15 PSI to get the last bits off and remove any abrasive that is still there (the white stuff) Total prep time about 6 hours. I also need to decide if I want to repair the broken right genal spine on the attacking bug and its left eye. I am thinking yes for the genal spine as that is an easy repair as either a mold of another bug's spine or a part from a spare cephalon if I can find a size match(always take home cephalons of greenops that have genal spines you never know when you will need one) Let me know what you think I should do in the way of repair/ restoration. I am thinking a restored genal spince will definately enhance the overall look of the piece I absolutely love this plate and it is staying in my personal collection.To me these are natures work of art. I am calling it "Attack of the Killer Greenie's". When you sit staring at a bug under a scope for many hours doing prep you have lots of time to think. In my wild and crazy imagination I can see this pack of Devonian raptors swooping in on the big fat Phacops ... a moment in time , captured forever. Actually this would just be the random way they ended up postmortem......but it sure is neat to speculate.... Again from a slightly different angle.... I would say that if you can find specimens like this at Penn Dixie it is well worth the trip. (Well I think so anyway) As I understand there are still a few spot available for the Sunday of the Dig With The Experts Weekend. I had hoped to be there helping out with my trusty saw and limited advice ......but as you would have know it my wife scheduled my daughters birthday celebration for the Saturday... So not this year...... Here are a few extra angles... Note that there is a partial greenops or Bella pygidium under the Eldredgeops..... Should I have continued looking......... Naw a some point you have to say it is good to go..
  18. While spending too much time and money at Princess Auto (Canadian version of Harbor Freight), I had picked up a rotary tool to remove some tool marks from a few prepped pieces, as air abrasion seems to take a bit longer. Before I set about doing that in earnest, I thought I may as well do another probing exploration of a shale slab from the Widder Formation from Arkona that has been quite kind to me. This was a piece I had entered in last October's FOTM, but I may as well show the slab's history... The first is how I found it during a trip to Arkona back in October with @Malcolmt, @Shamalama (who got the real winning find of the day with his Eldredgeops iowensis southworthi roller!) and @crinus
  19. Greenops sp.

  21. Arkona 17/09/30

    Yesterday, Deb and I spent four hours at our usual spot in Arkona looking specifically in the Widder Fm for Greenops and other related goodies. It was one of those lovely days where it isn't too hot or too chilly to get some real hammer time. First up is the bench I'll be working. This is from the very beginning of the day, left and right shots. I've been working on this bench for the last four or so trips. Where all the tools are resting is just below the rich Tornoceras layer wherein are also found a higher probability of full Greenops. Much of the stuff on top of that is bits or just brachs, shale that is dense and shatters or just comes out in chips. For this trip, I'll be focusing on following the "Torno layer" to the left and right of this bench, but it may also require some approaches from the top, and that means a heck of a lot of overburden and blank shale to remove (and I forgot to bring the pickaxe this time - derp!). And this is what it looked like after four hours. Sorry for the choppiness of the image as it was my attempt to stitch three shots in a panoramic. The second shot shows it from a distance, and the third shot where I am gradually connecting my bench to Deb's bench to the left.
  22. Deb and me just got in from a good six hour search for Greenops, carving out and extending benches. Did we find full ones? Well, yes and no. As those familiar with the area know all too well, finding a full Greenops is not easy. Apart from a zillion moulted pieces, their notorious delicate flakiness, and sometimes the frustration with the matrix itself, full ones - when they appear - rarely come out nice and pristine without some damage. I haven't been as much of a Greenops whisperer this year, but some pics of finds... First up are the heartbreakers - stuff that had the potential to be full, but for one reason or another wasn't. Next is a cluster of more heartbreakers, but there are two "full" ones in there, but with considerable damage on one and distortion on the other. The others in that group may prep out full, but they already display considerable damage. I don't usually find crinoid stems this far up in the Widder shale. This stem actually continues on the other side. Some very delicate prep, and I'm hoping I might find a surprise at the end of that stem. My rule about this orthocone nautiloids is, if it is intact, wrap it up and put it in the bucket. This might actually come free of the matrix.
  23. Trilobite pygidium, Greenops ?

    Hi folks, This looks like a Greenops pygidium but has slightly different spikes than images searched for ref. This was in my typical dig area. Devonian, mahantango, eastern WV. It is quite fragile and was very difficult to expose without totally destroying it. Can you verify / determine the species ? Thanks ! Cheers.
  24. greenops_widderensis

    From the album Trilobites

    Taxonomy: Greenops widdernesis Age: M. Devonian Location: Arkona, ON (Widder Fm) Source: Self collected. Remarks: Prepared by Malcolm Thornley. Specimen is complete and intact apart from some minor pleural damage on right side.
  25. Trilobite Trio

    Hi group, I think this is another greenops pygidium. If it is, this make a Trilo-Trio, all three species found within inches of one another. The Eldredgeops was peeking out of a natural fracture and looked like it might possibly be more than just a cephalon ..... but, no luck. Only had about ten minutes to look today, hope to get a chance to look more tomorrow. Devonian, Mahantango from eastern WV. Kind regards.
