  1. Hello, I am brand new at fossil collecting and am trying to get specimens for my science class (I’m a high school science teacher). I bought a few fossils pretty cheap not knowing how prevalent fakes are. I think some are fake, partially faked, or enhanced. I don’t want to misinform my students in what is real and what isn’t so I’d love some help! (Fakes aren’t the worst thing for me since we can discuss the use of models in class, I just need to know what is real or fake). Here is my first specimen: a trilobite of unknown origin (I havnt seen one like it online which is why I think it is fake). Thanks!
  2. A Tough Asaphus Prep

    After 48 total hours of very challenging work, an 80 mm Asaphus lepidurus is complete. I've prepared this species before, but this one was the toughest on account of very sticky, hard, calcitic matrix glued right to the shell, which meant very slow and extremely careful scribing under very high magnification. At times, I was removing matrix by the grain! This was the block when I received it with a bit of the bug poking out of the side.
  3. Real or fake trilobite?

    Hi, can anyone tell me if this is real or fake? I can see there are repair work done on it (which I dont mind). I just want to know if its real. Thank you!
  4. Meet my new Maurotarion axitiosum. It's not the finest example, but I am now only missing one of the main Haragan bugs, the Acanthopyge remains elusive. If anyone has one that they want to part with let me know. I probably can't afford it, but I'd settle for bits.
  5. I’m looking for a complete high quality Elrathia kingii still in matrix. If there are multiple on the same plate even better. I have a variety of fossils from the Chengjiang biota and several Devonian trilobites (Penn Dixie and Morocco) available for trade. PM if you’re interested! Thanks.
  6. Collecting trilobites

    Hey! This might be the wrong thread/topic but here it goes. I recently started collecting different species of trilobites. It would have been interesting to see what species others have collected and whether you can refer to some species in a medium price range that is worth collecting. I have a desire to compile a list for myself with different species that I can follow. Someone who has / knows about fine trilobites that are worth collecting? These are the species I have collected so far: - Flexicalymene sp (morocco) - Flexicalymene retrorsa - Coltraneia oufatensis - Hollardops mesocristata - Hollardops sp. - Ductina vietnamica - Elrathia kingi - Different phacops sp. - andalusiana cambropallas - Some unidentified species (will be posting pictures, some of you probably know) Thanks!
  7. Possible Trilobite in NJ Cretaceous?

    Found this in NJ Cretaceous stream. I've heard rumors that some trilobites get washed down from north Jersey, this is about an inch and a half long. Sorry for the crappy images, will work on getting more focused shots later. It definitely seems segmented. Any ideas?
  8. I´m certain that the fossil is real though im not sure of what degree of restoration that is done on the fossil. And im wondering if it looks like its covered in shoepolish or something? its kind of shiny in a unnatural way it seems Thanks!

  11. Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.
  12. Pre/Cambrian Collection

    I have always been quite fascinated with the early stages of development of life on Earth. My interest really picked up when I first discovered the Ediacaran biota, and who can blame me. Those creatures are so enigmatic and fascinating. I was able to pick up a few specimens, but quickly realized that my desire for fossils greatly outweighed the supply and cost of Ediacaran fossils, and I soon discovered the equally fascinating and enigmatic Lower Cambrian Chengjiang biota. I was, and still am, blown away at the quality of preservation of these soft bodied critters. A lot of specimens come very shoddily or incompletely prepared, and while it's been a steep learning curve, I feel that I'm starting to get the hang of prepping them. I've decided to start posting my latest acquisitions as these fossils are too amazing not to share. First up is Cricocosmia jinningensis, a fairly common palaeoscolecid worm from the Chengjiang biota. I have several specimens but this one is the best. It came partially prepped and I am just now satisfied with the result. You can see remnants of the gut preserved as darker regions in the center of the body. Next up is a small hash plate of Bohemiella romingeri brachiopods from the Middle Cambrian of the Czech Republic. Not my usual purchase, but I felt the specimen was too beautiful to pass up.
  13. My first 3D trilobite

    An unidentified species of Paralejurus, dated to the Emsian age of the Devonian. It's from Jebel Oufatene, Morocco. It's also my first 3D trilobite. Of course, I bought it, I don't have any skills in finding fossils and preparing them. They'll hopefully develop in the future though.
  14. Dear TFF Members, today this piece arrived from a seller, who unfortunately didn't know either the correct ID of the fossils, or the age - the only thing he knew in respect of the specimen was that it comes from the South of England. He suggested it's a water worm, but I would like a more precise ID. On the front of the rock - apart from the potential "worm" - there are also numerous trilobite tails. And on the back - an imprint of a snail? ammonite? , two parts of something that looks like shell and a chain of something? Absolutely no idea, what it could be . Please help me Front of specimen: With a flash: Close-ups of trilobites' tails:
  15. So i bought this fossil trilobite a while ago. Is it real? If so what genus, species etc. would it be? Ask if more pictures are needed.
  16. overwhelmed

    Hi all Never thought i would happen to say that, but this week end i put a final effort into cleaning trilos i picked during winter season and i have to admit it : I'm overwhelmed with trilos. Some of the visits had been the most productive i made and even if you dont come home with the quantity, there's always something to make the trip worth. Most of the best pieces had already made it to the shelves, i posted some in earlier topics. So a big part of what i finished are B grade samples. Some have their head more or less disarticulated, some the pygidium missing or damaged. So heres the group view of what i more or less finished over the past two weekends. I ll keep posting in this thread, the most noticable stuff once i got the pictures sorted, so stay tuned.
  17. Love at First (Trilo)Bite.

    Greetings, experts and seekers of expertise and knowledge. I posted an image of my first trilobite, along with a mosasaurus tooth and some images from the Ventura Rock, Gem, and Fossil Show, which took place last weekend. I posted it in Member Collections because it appeared to be the best spot. However, it seemed to have very limited views and comments, so I'm posting in the world famous I.D. section. I'm relatively sure that the little trilobite was correctly labeled, but it would be nice to have comments on that from the experts. I checked it against some images at trilobite.info, and it would seem to be from the order corynexochida. Admittedly, I'm very new to scientific naming, etc. Based on the time frame and physical appearance, it looks like corynexochida to me. It also looks like it is indeed a thysanopeltella (Scutellum?), as it was labeled. So is a scutellum a member of the order corynexochida? I guess I'm just looking for confirmation on the labeling, and of overall condition, prepping, etc. I realize that I could be all washed up on most of what I just said. I claim nothing but ignorance. Many thanks in advance. Cheers.
  18. Hi all, I have been searching through posts in the forum about various types of abrasives, and I can't seem to find a comment anywhere where someone breaks down the pros/cons of the different forms of abrasive and their microns. Of course I realize everyone has their own preferences, I am just confused as to the objective benefits of what looks like the three main types of abrasives: dolomite, aluminum oxide, and just plain baking soda (besides the fact that baking soda is more delicate.) The Paasche Air Eraser comes with 240 micron aluminum oxide, but that seems to be a little extreme for fossil preparation, is there an appropriate time and place in which I could use that? What would be the max (or even a general range) micron of either dolomite or aluminum oxide that one would recommend I use for 1. Green River fish, 2. trilobites, 3. ammonites, or 4. just general fossil clean-up?
  19. C. breviceps

    I bought an unprepped, slightly damaged Breviceps trilobite from HoldingHistory recently to see if I can actually prep something. No air pen, no air abrasives, no real tools at all. Just some needles, pin vices, dental picks, an old nylon cleaning brush from an electric razor & some hydrogen peroxide. Many hours later, I have gotten it to this. I may try to get the last little bits of matrix out of the crevices at some point, but for now I'm pretty happy with my first real attempt. 2 pics showing before, the rest current. Not too terribly bad, is it?
  20. Hello! I would like to know if you think that this trilobite is a good piece. The seller assures me that it is 100% natural, without restorations and with all the real spines. What do you think? This walliserops is from Foum Zguid I can get more photos or videos. Thank you. I hope your help.
  21. Help with cambrian Trilobite ID

    Hi there, I have an old trilobite that I bought 20 years ago as a pre-teen that I have now completely forgotten all details of. I remember it was from a US locality, definitely a cambrian age trilobite. It's pretty small, measuring about 7 - 8 mm. Looking at it now I think it's a Zacanothoides or Olenellus but I cant be sure. It has a long genal spine and what looks to be an impression of another spine at the tip of its pygidium. As a bonus, if anyone recognizes the locality from the look of the matrix that would be awesome. I was thinking Pioche Formation in Nevada but could be wrong.
  22. Trilobite Comura

    Always wanted a Comura but the prices are out of my budget so thought I'd try making one. Not as good as real but didn't have to sell my first born into slavery to make it. Its a Comura bultynici from the early Devonian.I added a photo of a real one. What a beauty would love to own one. . 800px-Comura_bultyncki,_Early_Devonian,_TazoulaOt_Formation,_Jbel_OufatEne,_MaOder_Region,_Morocco_-_Houston_Museum_of_Natural_Science_-_DSC01594.bmp
  23. Morocco trilobite feeler?

    Feeler is real? My freinds photo but feeler is look weird
  24. Trilobite question

    Bought this trilobite many yrs. ago there was no info on it at all but the eyes were so great I had to have it, I am pretty sure its a Order Phacopida but that's as far as I have gone. Family, Genus and species have a dead end in my searching, Not a super piece and am sure some it is missing some of the front of the cephalon which adds to the ID but would like to display it with correct ID. Any help would be appreciated.
  25. Hey guys, Just purchased this Crotalocephalina Trilobite and wanted to get your opinions on it. It's a really nice looking specimen. It's 72x34x18mm! Just a heads up the shine is due to having the lamp on Thanks
