New Year, New Topic! 2023! LINK to previous years' topics. Some super cool teeth arrived in the mail: some baby GW's from Peru (Pisco Fm.). Really great condition (razor sharp) and nice baby blue color on these rarer teeth. Upper left anterior (A1/A2) ~20 mm slant height. It's marginally larger than that of a full-term embryo, and comparing it to measurements of modern specimens in Dr. Hubbell's collection, the shark was probably less than 1.5 m (5 ft) total length. Neonatal GW's are typically narrower than the adults', and can have small, highly variable "cusplets" which disappear as the shark ages. Upper left anterior (A1/A2) 22 mm slant height. This one is from a slightly older individual, still likely less than 2 m (6.6 ft) total length. You'll notice that the crown has broadened, and the cusplets are already gone. Lateroposterior 13 mm slant height.

These fossils were bought for me at an auction selling scrap cuts. The location and age of these fossils is completely unknown. I believe the big ones are a Knightia species but have no clue for the two small ones. There's also a weird one that might be a clam. All photos are cropped and contrasted except for one of the small ones as it only made it harder to see. Paper is college ruled, each line is 7.1 mm Knightia?: Other two fish: Clam?:

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).

Some type of enantiornithes? Info from auction description: Age : Early Cretaceous (125 million years ago) Locality : Yixian Formation, Liaoning Province -
Suspicious auction tooth
Johnfossilhunter posted a topic in Is It Real? How to Recognize Fossil Fabrications
Dear all, I have recently encountered a very good deal on the tooth attached below. However, the deal is too good so I wonder, is it a fake or is there a chance for it to be real. Deal is around (price removed) for a 10.5 cm tooth Thank you for your help Best- 6 replies

this is shocking... Christie’s Pulls T. Rex From Auction, Citing Need for ‘Further Study’ - The New York Times (nytimes.com) but, for my opinion its the right decision and Black Hills is absolutely right. I am a bit frustrated that the selled did not give the right infos about the T-Rex, no teeth are original, that it is a "cast" of Stan and no one really knows how many bones are original.... When a fossil like this will be offered for sale honesty is absolutely necessary! Hope the seller will be banned from Auction-Houses

Today I drove out about 50 miles to attend an auction that is held a few times a year. This auction usually has Native American artifacts, Chinese artifacts, old fishing equipment, fossils and other odds and ends. The auction starts at 10:30 am and runs several hours. Today I left at 2:30 pm and there was still about 150 lots to auction out of the original 450 or so lots that the day began with. Today there may have been about 50 people in attendance and by the time I left, there were maybe 20 people left. There is no charge to enter and no additional fee is charged to you if you happen to win a bid. In addition, they provide a ton of donuts for breakfast and make sandwiches for lunch, all of the food is provided free of charge. They only thing that you are charged is $1.00 if you want a pop or water. I see many people that come and never bid, but do eat the food. Lol As with all auctions, you have to keep an eye on what is be auctioned at the time and you have to make sure that you don’t get caught up in the moment and bid more than you were thinking about paying. Here are some of the fossils that were up for auction. Most of these came from an older collector that had passed away and his niece was getting rid of some of the stuff. It was a Potpourri of things that included dinosaur pieces ( no teeth), Oligocene fossils, tracks, casts and other stuff. The main problem with these collections is that there is no information on the fossil or the location that they came from. A “lot” consists of what ever is in the flat. There were 3 Riker mounts of Mazon Creek fossils, none of which I bid on. The cool thing about this next Riker mount is that it contained a fossil that was collected and mounted by my fossil mentor Walter. Megalodon teeth are always sold separately, these 2 below were not very good at all and I do not believe that they hit a minimum that some other seller had set for them. This happens quite often on certain pieces and they will end up at the auction again. Some people think that there fossils are worth more than they are. They need to understand that it is only worth what someone is willing to pay for it. When some pieces do have ID’s, they are incorrect, such as these poorly preserved prints that are in Permian Coconino sandstone and are not dinosaur. Dino eggs that they said are real, but I did not look at them or bid. If they were real, the winner got a great deal. Dino stuff and some broken fish plates. A Dino centrum, there were a few. I was bidding on this next piece, but backed away after I saw that a guy who I had been talking to was also bidding, he did the same to me later. This next piece was a nice partial Rhino skull from the Oligocene (USA), location unknown. Some misc Dino bones and other things. This lot contained some poorly preserved Oligocene rhino jaws, a partial squirrel skull, fossil dung beetle balls and fossil locust / insect cocoons, most likely from Wyoming. As mentioned above-?dung beetle ball and insect cocoons. Misc stuff- Green River fish Santana formation fish Dino stuff and fossil Dino casts- I won this lot. This was something that I really did not need, but after sitting for a while, it feels good to bid. An Oreodont skull- I won this piece also. Here are the things that I picked up- A really decent Merycoidon gracilis Oreodont skull. I will prep it up a little more and I got it for a song. Believe it or not, this fake trilobite cast went for almost double of what I paid for the above skull and more than I paid for the Dino stuff below. And the above cast went for more than I paid for the below “lot” Dinosaur pieces that I won. Thanks to Frank @Troodon for helping with some ids, even though I had limited information on the pieces. Centrum from most likely a herbivore. Part of a Dino vertebra. This lot is continued on the next post.

Idea for legislation to reform the trade in Fossils of Large Vertebrates in the United States
Joseph Fossil posted a topic in Questions & Answers
I've heard very recently about the upcoming sale of the Tyrannosaurus Rex Skull Maximus and I'm horrified another priceless dinosaur specimen is once again out of the hands of science and into the hands of the ultra rich. This Smithsonian article is a great summary of what's happening, though it incorrectly states the specimen's age at 76 Million years old (T-Rex lived between 68-66 Million Years ago). https://www.smithsonianmag.com/smart-news/a-t-rex-skull-named-maximus-could-fetch-15-to-20-million-at-auction-180981116/ Though the fossil trade occurs around the world, this problem seems to be most concentrated in the United States as of recent. I think it's about time that the U.S revisit its national laws and pass reform to the trade of large fossil vertebrates. For one thing, there could be a requirement that the only ones allowed to participate in auctions like the Maximus one should be Reputable Museums since this is dealing with the Earth's collective heritage and (so Museum's aren't bankrupt by paying gigantic amounts of money to buy fossils from Private landowners), the State where a large vertebrate fossil was found in should cover the full payment within a reasonable period (maybe a month to 12 months) to the landowner and give the fossil to the Museum so everyone can have a chance to study the fossilized specimens. This is just me spitballing some ideas, but what do you think? Do you think fossil auction and trade reform legislation is necessary in the United States and if so, what suggestions/reforms would you like to see implemented?- 52 replies

I am currently at an auction right now, and I was wondering if anybody can identify this little trilobite? It looks odd to me and I don’t recall seeing one like this before, but I do not know much about trilobites. Any help would be appreciated. If it’s something nice, I might bid on it, it comes with other items as well it’s in the lot.

A couple of years back, I had an opportunity to meet @minnbuckeye and go on hunting trips to the Peace River and tributary creeks in Bone Valley with a few other TFF members ( @jcbshark Right from the beginning, I enjoyed being with him, his generosity, his humor, and love of life. He is easy to like. Plus , I seem incredibly lucky whenever I am with him. For example, right after we took this photo (when Mike donated some of the fantastic fossils he had found to the yearly auction of my local fossil club auction), I went out hunting (by myself) and found the Mastodon tooth. Ever since I considered Mike my good luck charm. Fast forward to this year. Mike PMed me in early March to offer some fossils for the upcoming Fossil Club of Lee County (FCOLC) March 17th (another lucky day) annual auction. I naturally accepted and as soon as the fossils arrived, transferred them to the FCOLC Secretary, who added many as auction items. I went to the Auction last Thursday, even though my muscles and back were hurting from a day of hunting in a creek. Mike's generosity resulted in many hundreds of dollars donated during the auction that goes to Kthru12 outreach, funding to Paleontology students at University of Florida, and better fossils in the Kids Digs. I got lots of Kudos and thank yous at the Auction from people who know me, but those Kudos were mostly due to Mike. I thought about how I could get something that might recognize Mike generosity and help my local fossil club. and the answer appeared ... I could bid on the next item #34 coming up for Auction... and send it back to Minnesota in tomorrow's mail to let him know I appreciate his role as a fantastic Ambassador of the community of Minnesota fossil hunter. Thanks Mike...

Sales just concluded a min ago. I definitely wasn't expecting it to reach this insanely high amount. No word yet AFAIK on whether he's going to a private collection or museum Is this the highest a dinosaur has ever been sold for? I wonder what precedence it'd set for fossils and paleontology moving forward On the pro side, it'd encourage more folks to go out there looking for fossils and possibly finding rare and important finds. On the con, more fossils might be priced out of the reach of museums

Prognatodon currii 'slightly' restored
charlie3425 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I just had another bad experience with the famous auction site wich I can not mention by name as I understand it. (Even my cat could find it in an encyclopedia though...) This time I placed a quick bidding on a - as it was advertised - slightly restored big fully rooted tooth of a Prognatodon currii. To my exitement I won the bidding. Taking a better look at the photo's of the item my doubts grew and on its arrival yesterdag my worries were allas confirmed. The tooth was firmly and totally cemented to the root with a mixture of sand and glue (in a colour nearly matching the fossil). Other breaklines in the root were cemented in the same way (this bothered me less). How about that for a 'slight' restoration. It is possible that the root and crown are just parts of two different fossils. Impossible to know. So I have this argument with the seller who claims the description mentions it is restorated and I should not expect any better for this price... So be warned. Ask for more information before bidding and zoom in on the pics if possible. I will quit my account for that website now. Looking back I can say half of the items I won/bought on it caused me some form of dissapointment. I'll buy from experts only, I never had any problems with scientists and experienced people. Should I give the seller a negative or neutral review? Or was I just too ignorant? Happy to shake it off a bit over here. It's not about the money, it's the new crack in my trust that hurts a little. -
My first fossil of the new year. Hopefully the first of many. A Hadrosaur vertebra from the Judith River Formation. Quite worn, but well priced and I've been keeping an eye out for a decent priced Hadrosaur vertebra for a while

Today I stopped by a local auction house, about 1 hour from home, that usually has Native American artifacts and fossils, today was no different. I picked up this nice mounted display piece of 3 pyritized Jurassic ammonites from Russia. When I arrived at home, I showed it to my wife and she stated that it was the prettiest fossil that she has ever seen me buy- Lol. Here are some pics of some of the other pieces that they had, some of these pieces went for prices that regular fossil collectors would never pay, it was insane. I am glad only one other person bid against me and I got it for $40.00. Horse cannon bones Trilobite- Isotelus (?) Madagascar ammonites 13” Woolly Rhino jaw- I had to tell the guy who paid a lot of money for it that it did not come from Nevada as the auctioneer said it did. Moroccan shark teeth South Dakota Oreodont skull and Stylemys turtle. There were bones that were supposed to be Dino and could very well be, with restoration, but I could not tell.

A new "T-Rex" tooth just showed up on our favorite site. It is not a Tyrannosaurus rex tooth however but a more common and far cheaper Carch tooth. We know this because of its more blade-like morphology, its slender profile, its shape, its smaller denticles and the sand on the base I already notice multiple bids on it and I have no doubt the price would escalate as many hopeful collectors would try their hands on getting a cheap T-Rex tooth for themselves. For anyone looking to buy a true T. rex tooth, there are several factors to take note of: 1) Thickness - T. rex had crushing teeth, hence the teeth are thick. They are meant to crunch through bone 2) Locality - T. rex teeth in the market commonly comes from the Hell Creek Formation and Lance Formation. These two formations are found in Montana, Dakota and Wyoming. If a tooth originates from Africa or Morocco, it cannot be a T. rex tooth 3) Price - T. rex teeth command a premium price. Even a small tooth an inch long may cost 500 USD or more. A 2.5 inch tooth would easily be 2k USD. While exceptions do occur, if a deal seems too good to be true, then you should be extremely wary 4) Source - Make sure you get your T. rex tooth from a reputable source. By that, I don't mean a seller with a high feedback score or someone who prints you a "cert of authenticity". I mean a seller who has a history of collecting or selling Hell Creek/Lance Formation material. Better yet, get it from someone who digs there 5) Morphology - Educate yourself on the differences between T. rex, Carch, Spino, Daspletosaurus and other large theropod teeth. That way, you can immediately spot inconsistencies such as serrations or colors that does not match a T. rex tooth 6) Cross section - If all else fails, look at the cross section. If the tooth has red sandy matrix or sand, it is most likely not T. rex but is more likely from Morocco Here, I will show an example of a red T. rex tooth that superficially resembles the Carch tooth above. Take a look at the thickness and cross section though and you would quickly realize both teeth have very different morphologies Getting an authentic T. rex tooth isn't cheap, nor will it be easy. But it will be worth it in the end when you finally obtain one. Good luck in your hunt and always feel free to ask TFF if you are unsure of an upcoming purchase

I picked this up recently from an internet auction house. The seller had no idea about it, since he knew absolutely nothing about fossils. I was hoping that someone might be able to guide me to at least the genus, when not the species and maybe also an idea about where it may have been found. The jaw partial is 5cm.long.

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.
