  1. Do you have thousands of dollars? How susceptible are you to financially ruinous bouts of pareidolia? I've been sort of fascinated by online sellers who seem to be genuine in their passion for paleontology but completely clueless, so I thought I'd share. There honestly doesn't seem to be any purposeful shenanigans here to shame, but I really hope nobody buys these. The item description for a sad looking cycloptic dinosaur head reads: (Seller ad copy removed by moderator) Lastly there's my favorite, a triceratops hatchling. I've included my professional forensic reconstruction of this lumpy little embryo for the advancement of science. If I'm wrong and these are actual fossils, I apologize.
  2. Tonight I decided to stop by the Chicago Rock and Mineral Societies 70th Annual Silent Auction which ran from 6pm - 9pm. This was the first time that I have attended this event and since it was a rainy night and only 40 miles from home I figured I stop by to see what they had. Here are a couple pics of the event- Most people were interested in the Rocks and Minerals and not the few fossils that were offered, and I hate seeing fossils up for auction and no one bidding, so I did and picked up a couple items that I did not need. This first piece is from Mazon Creek and I do love bark, so I got this piece for $3.00- Calamites bark with a great cross section of an internode. Here are 3 pieces of Pennsylvanian black shale that contain Shark Spines- these are from Illinois and I forget which Pit they come from and they only cot 50 cents each. I definitely did not need this next flat of Upper Ordovician Isorthoceras sociale cephalopods, but I could not just let them sit there without anyone putting down the starting bid of $1.00. I wrote down $1.00 and this was the last table to close and no one raised it, so I brought them home. I was planning on collecting from this site again this year after the MAPS Show. These two larger pieces of Turritella Agate from I believe Wyoming were a good price at $2.00 each- one slab is natural and the other slab is cut and polished on both sides. I also picked up these 5 echinoids and 1 gastropod that were supposed to have been collected in July of 1967 in Salenia, Texas- I picked these pieces up for 50 cents each. Here are a bunch of brachiopods and 1 horn coral that I got for a few dollars, but I do not have a location or age on these, If someone can help out it would be appreciated @Tidgy's Dad @Peat Burns- I believe that they are all from the same location. I’m thinking maybe Devonian from New York or Ohio? Here is a small trilobite that may be complete within the matrix- unknown location. I picked this up for 50 cents as well as this other piece with multiple brachiopods, believe it maybe Ordovician Sowerbyella rugosa. All in all, it was a good time and I helped them get rid of some stuff that they did not have to pack up and take back.
  3. Today I decided to drive 75 miles to a auction that was taking place near my house, yes I consider 75 miles near my house. This auction usually runs for several hours and has various items for sale, the bulk being Native American artifacts from the area and on most occasions, fossils. I had checked the info on auction prior to deciding if I wanted to go and seeing that they had a couple large mammoth teeth, I decided to go. Unfortunately when I arrived I learned that some of the pictures that were posted were from an auction several months ago that I did not attend. There were other “so called fossils “, but as you will see from the below pics, there was nothing that I would want. If I stayed and bid, I could have won each “beer flat” for $50.00- that would be all of the fossils in the tray. They also had 2 pieces identified as Permian Trackways. The Permian was correct, since it was sandstone from the Coconino Formation, but both pieces were void of any trackways. I am not going to even comment on the Moroccan Starfish. Now for your viewing pleasure-
  4. Was just looking through online, and found this item. Now, to me at least, I cannot see if this is just a regular rock. There seems to be some sort of honey-cone (bone) structure in some places, but I just cannot see how this is a real deal psittacosaurus skull. Seems a little too good to be true. What are your opinions guys?
  5. Auction

    Well I decided to take some time off of painting the house and drove 45 miles to an auction. This auction goes on about 5 times a year and has Native American artifacts, military items, old fishing gear and yes, fossils. The majority of the fossils are fake Moroccan, but sometimes they have other things- today they have a large slab of trackways from the Coconino Sandstone that I am interested in, but it is so far down the list, I do not think I can wait. Here are some pics of The offerings- most of the flats will sell for about $50.00. Trackway Slab- standard pen for size reference. The could have cut this slab down a lot since the trackway is in a narrow region of the slab. This fake Starfish plate just sold for $75.00. Other stuff-
  6. Another Auction Prep

    @holdinghistory was the winner of the most recent prep auction that I held to support our great community here. He sent me a Diplomystus from the Green River Formation 18” layer. I finished up some other preps and got started on this today. Here’s how this started out:
  7. Mammoth vertebra?

    I've been watching this vertebra on our favorite auction site and am not quite sure if it's from a mammoth, and neither is the seller, since he's placed a question mark along with it. Could someone more knowledgeable than myself please confirm or deny this? I'm thinking that it may be from some other kind of animal. I'm afraid there's only one photo. It measures 11.5 x 11.3 x 10.5cm.
  8. MOROCCAN DINOSAUR TAIL AUCTION

  9. Almost can't believe this... "Mastodon tooth"
  10. $640,000 MAMMOTH

    A snip at this price http://www.bbc.com/news/world-europe-42379425
  11. Posted are a few concerns I found wandering through the internet. These are but a few examples of the type of issues you may encounter. I send this out as a reminder if you're shopping for fossil presents of any kind. Sellers mis-identify material simply through lack of knowledge but it's up to the buyer to know what they are looking at. Don't hesitate to post interests BEFORE you buy. BUYER BEWARE when it comes to fossils of any kind. Seller wants huge money for this Saurolophus osborni lower arm from the Two Medicine Formation. Looks like a nice arm but some of his facts are incorrect. This species is not found in the Campanian of the Two Medicine Formation but the early Maastrichtian age of the Horseshoe Canyon Formation. Another key point is that it's very difficult to determine taxons from post cranial bones of Hadrosaurs especially in an fauna where multiple species exist. Nice lower arm from somewhere and from some unknown Hadrosaur. What's this seller thinking the "2 Medicine Man Formation" really attention to detail not one of his strong points. Someone tell him its the Two Medicine Formation. Maybe he watches lots of Westerns Seller describes this as Pachycephalosaurus in my opinion it's Thescelosaurus Seller is properly describing this beautiful jaw as Ornithischian but in detail description adds that it was discovered where many Pachycephalosaurus fossils were found giving one the impression it's Pachy. In my opinion it's Thescelosaurus. Teeth of these two species look similar inquire before you buy. I see a lot of these being offered or sale, nice Christmas gift. For those of you that are new to collecting the only thing real here are the crowns. Nice gift Seller is offering this Claw and Identifying it as Velociraptor from the Hell Creek Formation. It's a very worn Anzu wyliei hand claw.
  12. seen this for sale and to me it looks genuine but i am wondering about its authenticity, its location has no red flags as is Washington (not Cincinnati) any input would be appreciated.
  13. Dinosaur Ridge Rock Out for the Ridge

  14. Auction Prep Part Deux

    I'm almost caught up on prep jobs (3 going concurrently now) so I figured it's time to start in @RJB's monster fish. Here's how it arrived at my humble abode... Wow, what a fish!!!!! It rests in a 1" thick slab of 18" layer matrix (read hard as concrete) and Ron was nice enough to mount it to a 1/2" cement board... I think I got a hernia lifting it to the prep table. Needless to say, it is rather stable. Now for the prep...
  15. So I may or may not get killed for my recent purchase, I jumped at it when I received a offer and now I'm freaking out a bit. Could you please help confirm that this indeed real and then possibly I'll be out of hot water. Thanks!!!
  16. There are a lot of Asaphus kowalewskiis on a particular auction site, that range in price from 100-300 dollars. Are these legitimate? They all come from Russia, Finland, Estonia, and that region. I know there's always some restoration to the shell, but are they ever faked outright? Example attached
  17. Fossil auctions

    Hi. I have an ammonite block which I would like to sell in an auction to support the forum. Am I old enough to sell fossils in an auction? (I am 15.) Thanks, Daniel
  18. Please be aware there's a bunch of supposed Ankylosaurus fossils on our favorite auction site. They are sold as Ankylosaurus armor, or tail plates. There are other similar pieces of maybe-fossils sold as Ankylosaurus parts, along with pieces of rocks sold as dinosaur eggs. I admit my knowledge in Ankylosaur fossils is limited, but I see absolutely nothing about these that's indicative of authentic Ankylosaurus fossils. No locality is given either. Please be on alert when you see these, along with the sellers' other suspect items. Real Ankylosaurus fossils should firstly be sold by a reputable dealer(since they are hard to identify properly), they should have bumps/ridges indicative of armor, and should have a rugose/wrinkled/bumpy texture. They are found in the Hell Creek Formation, Lance Formation, and Scollard Formation. Here are pictures of 4 authentic specimens for your reference.
  19. I know I'm not the only one that doesn't live near good fossil deposits, which means that i'm not the only one that has to buy or trade fossils from time to time to build the collection. I thought it would be fun to have an ongoing thread to share our latest great score that we didn't personally find in nature, a thread to share your latest fossil purchase or trade. Let's see what you found at the local fossil show, online or anywhere else other than in the ground.
  20. Hi Everyone, I've been shopping for a Spinosaurus Jaw for a little bit and saw this guy online. I did search previous posts on Spino jaw ID but I thought I'd open it up to the group as I was unable to determine if it was croc or spino. Thank you
  21. Recent auction post labelled 'MOSASAURUS FOSSIL TOOTH ROOT BONE'. I'm a little new at this so bear with me but - The root bone looks real but the teeth look placed. Is it a red flag that one tooth curves to the left while the other curves to the right?
  22. Auction Prep

    I started the preparation that @snolly50 won on my auction. Here's a pic of the fish as I received it.
  23. Whole dinosaur eggs are highly sought-after fossils. The ones usually available to collectors are Hadrosaur eggs, Oviraptor eggs and Segnosaur eggs from China. This thread deals specifically with hadrosaur eggs. Hadrosaur eggs (Dendroolithus sp.) as we know from the market are in fact various dinosaur species, often hadrosaurid (many collectors/dealers lack the tools or discipline to examine eggshells under microscopes or have accredited museums examine them). Commercially available eggs vary greatly in price, anything from 150 USD to 1,500 USD depending on quality, size, hatched/unhatched and prep work. They usually range from 3.5 inches to 7 inches in diameter, and are mostly hatched types (which means the egg is in fact empty. If you prep out the bottom matrix, chances are it's hollow). However, hadrosaur eggs are also one of the most commonly faked, or mistaken fossils in the world. Anything from pieces of rock, pebbles, septarian nodules, concretions, or even chemically-etched objects are sold as eggs. There are several online right now. Here are examples of false hadrosaur eggs we often see in the market. Here are examples of partial/composite hadrosaur eggs (Note these ones are real to an extent. They can be a more economical choice as long as you know what you are getting).
  24. Dinosaur skin are a highly sought-after fossil. The ones usually available to collectors are Edmontosaurus skin impressions from Lance, or Hell Creek Formation, and they aren't as rare or expensive as you might expect, fetching up to 100-200 USD per inch depending on quality. However, it is easy to mistake a bumpy piece of rock, mud sediment, septarian nodule, concretions, or a coral fossil as dino skin. Right now there are at least several of such on our favorite auction site. Here are examples of fossils/pseudofossils mistaken as dinosaur skin: And here are real Edmontosaurus skin impressions: Positives: Negatives: So how do we tell real skin impressions from misidentified ones? Honestly, it isn't always easy, but here are four basic guidelines. 1) Skin impressions come as negatives or positives. If it comes with both, even better! 2) Skin impressions are rarely ever a complete piece by themselves(not the way a tooth or an ammonite is). Instead, skin impressions are often fragments, or look like they are broken off from larger chunks 3) There should be a uniform shape to each individual scale/osteoderm. Refer to the negative pictures above 4) Most skin impressions come from South Dakota. If you get another locality, be on extra alert - it's either another species(and thus very expensive), or misidentified If in doubt, ask the forum before purchasing. There are plenty of experts here glad to help. Have fun shopping!
  25. Today in online shops and auction sites, we see listings that are outright fake or with wrong IDs. Often, the first thing that comes is anger. "Why would he sell theropod indet. as raptor?" "That Keichosaurus is obviously fake!" "That's horn coral, not a T-Rex tooth..." etc. And in our anger, or need to prevent others from falling into the trap, we might post on the forum or spread it all over FB to warn others of this seller. Yet have we given the seller the benefit of the doubt? What if he/she made a genuine mistake? Recently I posted a thread filled with sarcasm and rage-humor on how a coral was marketed as an expensive sea bird fossil. It was too easy to ID the seller from my title and pictures. The mods thankfully closed the thread. Fossildude19 then contacted the seller, and reported the listing on the auction site. In 2 hours time, the listing was taken down, and the seller apologized for his mistake. The problem was solved quick and clean. I do not deny there are plenty of sellers out to scam. I do not advocate mercy for them, but I wish to tell you guys(and to remind myself) that some sellers are guilty of ignorance, not malice, and we should give them(and the auction site) a chance to remove their listing first. I know some of you are thinking - dealers have an even bigger responsibility to do their due research, and their laziness or mistakes causing buyers to lose $$$ isn't to be taken lightly. I agree. But we don't need to start witch hunts for them. All in all, I used to think reporting listings on eBay didn't work, but Fossildude19 proved it does. So give it a try guys; you can refer to this thread on how to do it >
