  1. Trilobite question

    I know that Metacanthina is now called Hollardops but I have a Hollardops that has a spine right on the center of the cephalon where it meets the thorax. Is this a Hollardops or something else.Thank anyone for advice.
  2. Okay so I found this specimen at the Taughannock Falls in Ithaca New York. I found it at the edge of the gorge which consists of Shale, composed of slit and clay that fell onto lime mud and hardened into rock. I've done some research and it appears to be a Brittle star trace fossil formed by their arm grazing the sand floor. Although, these Brittle Star fish traces are known as "Pteridichnites biseriatus" and they have only been discovered so far in upper Devonian shales out in western and eastern Virginia. I'm not an expert but to my knowledge the Ithaca geological formation is Devonian and was slowly covered by sand. Is it possible that the Brittle Star fish once roamed in the ancient sea now known as "Taughannock falls" today? Because a research team is trying to find this specimen and they are wondering if anyone has discovered it. Edit: Im referring to the dotted trackway. check this link out for more information. http://www.wvgs.wvnet.edu/www/news/Pteridichnites.htm
  3. I have a dinosauromorph foot print is it rare? I will upload photos of my collection when I get home later today so stay updated.
  4. Came across this piece of petrified wood awhile back and was just noting the odd red markings in the second photo. Any idea what would cause such unique markings on petrified wood? I've never seen such before...
  5. I don’t know if this question is in the right place, I’m sorry. I’m not asking because I want to sell anything. But.... I was browsing the member trade section and noticed y’all do a secret Santa, (HOW FUN!!) the rules state that the gifted fossil’s value should be worth approximately $30 that got me wondering.... how would you even go about estimating the monetary value of a fossil you find yourself? I’ve been fortunate to find very beautiful things but to me they don’t have a for sale value so I wouldn’t know where to start in my collection to find one that is about a “$30 fossil” lol Sorry, is this the dumbest question I’ve posed yet?
  6. Weird stuff/cool stuff

    I have some pictures of weird creatures that I had been collecting online(pictures, not creatures), but never getting around to anything with them, and I keep having to delete them to make room, so I figured I'd just make a thread dedicated to the idea, instead of a thread each time there's a crazy knew whatever I come across. Please feel free to give any info or thoughts, answers or questions about anything brought up, and if there's any weird or particularly cool creature you want to mention, go ahead and post about it, preferably with a picture. it's ok if you don't have a picture, for instance someone might not even know what it's called, and can only describe it some. go right ahead and bring up something new anytime, or to bring something from earlier back up, even if it hasn't been talked about in awhile. If you're posting about something that's not currently being talked about, just be sure to either start by quoting something about it from before, or just preface your post with what thing you're talking about, that way people will know what you're talking about, and won't get confused. If something is getting heavy discussion, anyone can start a new thread to move discussion of that creature over, to make it easier, but if you do, make sure you post the link to the new discussion thread, for everyone! *to avoid confusion, if you're not continuing the discussion from the previous post, just be sure to refer to what you're talking about.
  7. Broken woolly Rhino skull, Need Help!!!

    Hi guys, Recently I ordered a partial wooly rhino skull and as you could imagine I was on the brink of tears when it arrived. I ordered from overseas and someone must have dropped the box or something? but I am contacting the seller to see if I could get a partial refund (but I have my doubts). So I am trying to be positive and make this my "not so little" prep project, there is one problem though. I have no idea what I'm doing! (I don't even know if It's salvageable) So this is where you amazing people come in. I would love to get this looking as original as possible and was wondering if there was a product for that, or if I could just use household items, Or maybe there's some other solution that is foreign to me? Anyway, I would love to here every idea and any advice you've got. I have taken some pictures that are listed below, the last two are it in the condition before it was sent. If you need any more pictures to refer to, Please! contact me otherwise thanks for taking the time to read this and hope to hear from you soon. Thanks so much, Ryan.
  8. Hello everyone, I am in desperate need of help with a huge debate I have been having with a friend over fossils preserved in ironstone concretions. From some of what I had read to some advice from other members I it possible to find vertebrate bone among shells and other mollusks preserved in an ironstone concretion. Whether it leaves a trace of the organism, morphs the organic material into the structure of the iron concretion through the decomposition with preserving, or whatever else it may be it seems to be possible. So recently I have hunted a place known to have recorded marine cretaceous shell and other mollusk found in ironstone concretion as well as cretaceous plants in shale, it seems like not to vast of enough study has been done there only from what I know, but since no vertebrate material had yet been discovered there though there can maybe be the possibility. I found these two particularly distinct pieces in iron concretions that exactly mimic the scute structure of soft shell turtle and croc in my opinion, I know how iron concretions are famous for leaving psuedofossils and such but these two pieces look way to exact and since its possible for shells and mollusks to preserve why not scutes? So I am here looking to end this debate, I'm looking for your opinion, can these be labeled as fossils, traces, etc? Or are these among some of the world's best iron concretions and nothing more. Your input especially if you are very experience in this subject would be tremendously appreciated.
  9. Hello I present an interesting question that I'm not to confident to answer myself and am seeking help from the more knowledgeable. Since it seems like (from what I had seen) iron concretions can at rare times preserve certain fossils or traces in one way or another such as molluscs, brachopods, and such. Due to this would it be possible for material such as turtle shell scutes or maybe even croc scutes to turn up in such concretions in one way or another? (the pics are just snipets of general info that I came across online)
  10. Hey guys, Today i bought a necklace of a supposed tooth fossil from a sperm whale. However, i don´t think it is from a whale. In the same way, i don´t know if it is a fossil. What do you think about? Here are the pictures. Greets from Mexico.
  11. Does anyone know? I hear there's many fossils there. On all of the maps, though, there's no name for the creek. I know it's random, but I just want to try hunting there with a friend. Thanks! ~RiseOfTheExtinct
  12. Can't Identify

    Morning! I was fossil hunting along Calvert Cliffs, MD this week and saw a weird pattern in the cliff wall line. I found a plate with unusual patterns on it. At first I thought it may be a turtle shell but now I'm thinking it may not be. I would love to get some insight. Thanks!
  13. Is this even a fossil?

    I found this “rock” on the beach in Key West, Florida a number of years ago when I stepped on the bulbous part. The shape interested me so I kept it. Recently while watching a documentary about fossils it occurred to me that this looks strangely like part of a fossilized femur. I was wondering if anyone can identify this and confirm or deny my suspicion. Also, if it is a fossil, approximately how old might it be?
  14. Cataloguing software?

    My ever expanding fossil collection is without documentation. With all the details of the fossils in my head alone, is there a software or website capable of cataloguing my collection? Ideally i'd like to be able to upload photos of each fossil and fill in custom parameters and notes for each. Does something like this exist? Note: I am running macOS Sierra version 10.12.1
  15. I've seen people acid prep their keichousaurs and they come out beautiful. I know nothing about acid prepping, so what would I need if I was going to prep my own keichousaurus? Is it as simple as soaking it in chemicals to melt away the rock?
  16. What kind of clay is best?

    So I've been trying to get creative with fossil displays, and I've seen people use a kind of clay to display their fossils and ID cards. What kind of clay should I look for???
  17. I was curious about the bare snouts I see on art/restorations of dromaeosaurs (and maybe other feathered non-avian theropods, but I mostly associate it with dromaeosaurs) and tried to do a bit of Googling on the topic, but I've found conflicting reports on whether or not there's strong evidence for it and not much in the way of actual specimens/papers that relate to it. I thought I'd throw the question out here, as I'm sure some of you have thoughts and/or sources on the subject! (Related: if at least some of them did have bare snouts, do we think they would have been covered in scales or bare skin?)
  18. Academia.edu?

    Question for the room. I didn't know where to put this, so I posted it here. Does anyone on here have access to Academia.edu, or to any other solid sources of searching published academic papers? I keep getting notifications that I have been cited in a few highly cited papers, particularly ones pertaining to paleoceanography—which if anything I ever did was to ever be cited—would probably be pertinent to that. There is a far more knowledgeable Jay C. Wollin in the field, but I don't think he does much with marine fossils. I'm just curious to know if any of these citations could be related to me rather than him. (Not entirely likely, but I admit, the constant notifications have me intrigued.) Thanks, everyone!
  19. Howdy. I always see green river stingrays that are "inlaid." I THINK inlaid means they took the stingray and placed it into a better looking matrix, is this correct?
  20. No Idea If It IS One, If Not, So Sorry!

    Having read the new member posting cautions, do not want to waste anyone's time. We're just baffled. Besides splitting shale, once in awhile finding grass or fern ( since we were kids ), spend a fair amount of PA time crawling around Appalachians looking for Native American petroglyphs, etc. They're around, sometimes in odd spots. Fun, poking the camera somewhere promising, one time in a thousand you'll find something interesting ( besides a snake ). Only using ' Fossil ' ID because it looks like it was alive? Found this, last year. Went back several times after going through pics. It's beneath a flat-ish, large rock perched among a ton of others, promising niche, sometimes old carvings survive when protected. It doesn't seem to be one, not any we've come across Tough getting pics, pretty ' in there '. What on earth is it, please?
  21. Since getting into fossils something has been bugging me alot about material from the Jurassic and especially material from such places as colorado, utah, etc. Alot of bone material I see online for sale, mostly fragments in various sizes are usually unlabeled and generalized as being from any dinosaur from the Jurrasic. I wonder if there is at least a way to differentiate at least herbivore bone from theropod bone (like allosaurus from camarsaurus)? Is it similar to the method used for cretaceous bone of the honey comb pattern or not? I'm curious why it seems harder to identify Jurassic bone piece, I'd appreciate any input or discussion, thank you. For example would the first two pictures be considered theropod and the last herbivore?
  22. Matrix Question

    Hi forum, I'm currently looking at a Plesiosaur tooth from Morocco. The listing says, preserved in phosphatic matrix. Does this mean it was found like this, or placed in this by the seller? Thanks
  23. Ok this might be the most stupid question you have even had on here but it's bugging me and can't seem to get any good pages or images on google, and it is basically to do with the scapula and coracoid, how would it have been attached to the main skeletal system of theropods? as from looking at museum's and models it seem like it is just slapped on the side of the ribs which would not have provided much support or structure, and with sauropods would it have been attached to fused vertebrae like it would be for sacral vertebrae? Thanks for you time to read this. Matt
  24. Another Austin creek find.

    So I have another one for y'all. I found this in the same creek as what I now know is a rudist (thank's guys). Any ideas?
  25. Simple question is this trilobite real partially real or completely fake I understand much of large Cambrian trilobites are completely fake and have no actual genuine fossil remains in them I would like to be informed of which category this "fossil" falls into thanks in advance. (I'm expecting all the replies to be fake if it is completely fake with no fossil remains at all I ask for advice on what to look for next time I know most of the common signs only after the purchase of the "fossil" but before I completely give up the idea of a genuine fossil I figured some more experienced people could look at it again thanks in advance.
