Green River Fish Fossil for Dinosaur Fossils
Nanotyrannus35 posted a topic in Member-to-Member Fossil Trades
So this is my 1st time on the trade forum, so I hope I'm doing it right. I have this partial green river formation Eohiodon fish that is about 6 inches long that I self-collected from the split fish layer and I would like to trade it for dinosaur fossils. The fossils that I would want would be tyrannosaur teeth partials, and fossils from the Hell Creek and Judith River formations. Here are the pictures of the fish.

A tooth of early tyrannosauroidea members from northern China
Agent_Zigzag posted a topic in Member Collections
Greetings! This is my first share on this forum. I was looking through my collections, and one thing popped my mind was this tooth -- a tooth of Xiongguanlong baomoensis，which i found in 2014 but I could not give a very conclusive identification until earlier this year. I was lucky enough to travel along with a group of scientists into the Gobi desert in Northern China. That day we was traveling in the border zone of three different provinces, basically middle of nowhere. This basin is where most dinosaur from Gansu found -- including X. baomoensis, Auroraceratop rugosus, Lanzhousaurus magnidens, etc. I found two dozen of borken teeth on a random hill. In the beginning I thought those teeth could be either iguanadon, hadrosaurus or some crocodilians. After collecting them and bringing them back to Beijing, I went focusing on other real-life project (preparing for college, preparing for grad-school, etc.). It became a memory sealed in attic and lost until I was re-examining the crocodilian fossils I found from the same trip. Then my eyes fell on this tooth, which I recalled seeing similar teeth from the Lanzhou Geological Mesuem and labelled X. baimoensis. After a further comparing with other teeth from the same clade in museums in China, I am certain that this tooth could belongs to X. baomoensis. X. baomoensis is one of the most mysterious member of the superfamily Tyrannosauroidea, and only thing I could be sure that they could grow larger than the specimen preserved in Lanzhou -- for I found a large theropodian matatarsal from the same site and it's certainly larger than the skeleton they demonstrates. I put it somewhere in my mountains of boxes, please allows me some time to look for it.

Greetings everyone! I am a fossil hunter and a graduate student from Beijing, China. Most fossils I collected is from the Mesozoic sediments in China, composing dinosaurs, crocodilians, turtles, fishes, invertebrates and plants. I do possess some other fossils, including mammal teeth from cave sediments in Southern China. The following picture is a fragment of a theropodian dinosaur from Yunnan, China -- not a recent photo, dated back to 2017. Nice to meet you guys.

Good evening, I recently went fossil hunting in Dawson county MT in the Hell Creek formation. I believe that the fossil I collected is a possible dinosaur vertebra. Is there any way to determine what dinosaur this maybe and if it is a vertebra? The measurement is 7 inches long and 4 inches wide. Thank you, geogrl

While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.

Harryhausen. A trip to the Scottish National Gallery in Edinburgh
Welsh Wizard posted a topic in A Trip to the Museum
We’ve just been to the Scottish National Gallery of Modern Art in Edinburgh to see the Ray Harryhausen exhibition. The exhibition contains models and drawings that Ray Harryhausen made for his various movies. It was a great exhibition and well worth a visit. It had all the models from my favourite films like Jason and the Argonauts, Clash of the Titans and the three Sinbad movies. Why this thread on the fossil forum. Well Ray loved dinosaurs and he was lifelong friends with Ray Bradbury who also loved dinosaurs.

Ankylosaurus/Nodosaurus Ungals and Foot References?
Kurufossils posted a topic in Questions & Answers
Hi, does anyone have or know where I can view images of a ankyloaurus/nodosaur foot but especially the ungals? Having a hard time finding images for a comparison. -
I saw a dinosaur supporting bone. Excavated from Madagascar. But I don't know the variety. His minimum perimeter is 60.5CM. Can you determine the weight? About?

From the album: Lance fm. Microsite Finds
While far less famous than its horned and frilled relatives, Leptoceratops were interesting small herbivores in their own right, likely utilizing their deep set jaws as a deterrent for predators. So far this is the only tooth from this genus I've found so far. -
Looking for unprepared vertebrate fossils
Natalie81 posted a topic in Member-to-Member Fossil Trades
Hello, Since all those covid restrictions I haven't got the opportunity to go look for fossils outside of Belgium. So most of our trips from the last year are almost exclusively in the devonian. To get a little change of this I was hoping to find some unprepped vertebrate material, it dousn't have to be complete and I am not afraid of some puzzel work, but the pieces need to be recognisable. I can offer a multitude of different fossils for trade. ( Ammonites, spiriferids, shark teeth, sea-urchins,...) Natalie -
Hi, everyone. I’m brand new here, so, pleased to meet all of you! I’m wondering if any of you know of locations in the US where you can dig for dinosaur fossils (body and/or trace) on a one-day-at-a-time basis and keep some of the material found. Thanks in advance.

Dino Egg authenticity - real?
BrettCo124 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey everyone! I posted this on a Facebook group and had some great responses. My question is, I recently purchased a segnosaur egg from a reputable dealer who has been selling Dino fossils for a long time now. I have read how some Dino eggs might be fake, and I figured I’d just ask the question and get your professional opinions. Because of the reputation of the dealer, I do believe it’s authentic. It’s not like I bought it off of online from a random person, but I still wanted to ask the question. What do you think? I appreciate your feedback. IMG_9607.MOV

Hello everyone ! This Tyrannosaurus rex tooth measures 1 7/8 inches, has great enamel and great serration. I wanted to ask, how much can such a tooth be worth? and I would also like to know, how big was the whole tooth? Can you deduce from these photos? Thank you

Hi everyone, found this in a new jersey cretaceous creek. Looks like a partial enamel something but I'm not exactly sure what it can possibly be from, it interestingly has some very defined ridges on the least worn side. Very hard to catch the clearest pics to show the sharpest definition but I tried to get the best I could. Maybe this can be a clue to a potential id. Pictures of it with whiteish background are upside down.

This may sound like a stupid question to the more seasoned collectors, but I've recently started buying dinosaur teeth to collect and I can't help but notice a pattern when searching through the various fossil websites. Almost all dinosaur fossils are American or Moroccan. I've seen that international fossil trade is actually illegal in some countries causing some fossils to be unobtainable realistically. Some fossils are also extremely rare as well and are valued much higher making them extremely difficult to find.. Is it really that common for dinosaur fossils to be unobtainable? I don't mean the rare ones, I mean there's absolutely NO WAY to legally purchase them. I've seen the usual suspects on almost every website. Tyrannosaurus, Spinosaurus, Triceratops, Ankylosaurus. As well as certain Raptors, Pterosaurs, and theropods here and there. There are certain popular dinosaurs I never seem to come across though. Giganotosaurus? Brachiosaurus? Suchomimus? Are these dinosaur fossils just hard to come by or are they unobtainable to the average collector? If they are available, what's the best way to obtain them?

HI! I am Ashton, I love fossil and paleontology! I also love anything to do with science, animals, and nature! My favorite dinosaurs are all the weirdest ones like Deinocheirus, Concavenator, and Spinosaurus.

A new genus of Troodontid has been described from late Maastrichtian fluvial deposits of Spain's Talarn formation (Tremp Group). It was named Tammaro insperatus named for a small, elusive creature from local folklore and the latin word for unexpected due to where it was found. Very interesting to see this family of dinosaurs officially represented in Europe's fossil record, along with the overall diversity on the continent when it was still archipelagic. https://www.nature.com/articles/s41598-021-83745-5 http://www.sci-news.com/paleontology/tamarro-insperatus-09426.html Holotype metatarsal II http://cdn.sci-news.com/images/enlarge8/image_9426_2e-Tamarro-insperatus.jpg Artist's reconstruction (Oscar Sanisidro): http://cdn.sci-news.com/images/2021/03/image_9426_1-Tamarro-insperatus.jpg

Breakup of a long-period comet as the origin of the dinosaur extinction

I found this specimen along with some other fossils during a fossil hunt. This vertebra is very peculiar and unique, due to its small size, and it’s composition. It is completely permineralized by hematite, making it feel much heavier than the average rock. It almost feels like a chunk of metal. Probably belongs to one of the endemic hadrosaur species of the Cerro del Pueblo Formation, such as Velafrons coahuilensis, or Latirhinus uitstlani.

Giganotosaurus Tooth? Or Carcharodontosaurus Dinosaur Tooth Fossil
Kurufossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone, I was recently offered this Giganotosaurus tooth. I was wondering if there was a way to distinguish it from carcharodontosaurus teeth from the kem kem beds? Or if anyone can share there opinion on this one, thank you.
