  1. Hi, I’m new here! So I recently won an auction for what is easily the most charismatic fossil in my small collection: a nearly complete scapula of an adult hadrosaur (edmontosaurus?) from Hell Creek. (with PNSO corythosaurus for scale) I’ve never had a fossil anywhere near as big or fragile as this one, and I’d like to learn how best to take care of it. It was reassembled and gap-filled/restored with a gray adhesive and a white putty (epoxy?). The putty was concealed with brown acrylic paint. It doesn’t look like there’s any protective coating. (I’ve asked the seller if they can tell me what products were used for prep. They said they’d look into it.) Most of the middle area here is restored. As sold, the scapula was in two pieces. I’m not inclined to try to reconnect them because (1) the fossil is easier to move in two pieces and (2) it looks like they may not connect properly anyway because a piece of the distal blade didn’t fully lock in during reassembly. The break During shipping, a piece of the glenoid and a small chunk of the distal blade re-broke. Glenoid piece with gray adhesive Distal blade piece The preparer covered some areas of natural bone with acrylic paint in an attempt to make the restored areas blend in. I would rather the restorations be visually distinct from natural bone and I hate seeing paint on bone, so I tried removing some of the paint with a Q-tip soaked in isopropyl alcohol. That seems to work well without any harm to the bone, as far as I can tell. Restored areas with smeared paint Finally, although most of the fossil seems reasonably sturdy as restored, the crumbly bits at the end of the distal blade are really spongy and fragile and I think a consolidant and/or coating might be desirable. Crumbly bits and smeared paint I don’t want to attempt anything super complicated, but I’m thinking about doing the following: -Reattach glenoid and distal blade pieces with superglue gel -Consolidate end of distal blade with low-viscosity superglue or Butvar -Using rubbing alcohol and cotton swabs, continue to slowly remove acrylic paint smears until it looks “good enough” -Give the whole thing a protective matte or low-sheen coating (Butvar?) Is any (or all) of the above too risky for a beginner to attempt on a piece like this? Any recommendations, things you would do differently?

    Protohadros Age

    Howdy all, I've recently aquired a protohadros tooth and I've heard some people say that the genus is 95 million years old, and some who say it's 75 million years old. Which is the correct age?

    Edmontosaurus teeth

    From the album: Hell Creek Formation Microsite

    Edmontosaurus teeth, straddling its ontogeny. A) young juvenile teeth; B ) maxillary tooth; C) large adult dentary tooth
  4. Hello everyone! I'm going to start posting fossils individually, to gain more traction on the forum. I'll post a few fossils I am worried are fake or composite today, then repost any fossils I have yet to receive identification for with higher-quality images in about a week. I bought this Edmontosaurus tooth fossil from a somewhat unreliable website online. Is it real? If any of you need more high quality photographs, please tell me. Also, as I don't know where else to post this, I purchased this Tarbosaurus claw replica a while ago. Do any of you know which digit it comes from? Thank you and hope you have a good day!
  5. One of my favorite fossil types. Dinosaur eggs come in all shapes and sizes — from an oval as small as a thumb, to a sphere as big as a basketball. These fossils are often faked by the hundreds, if not thousands, in Chinese factories (China is also the world's richest source of true dinosaur eggs). However, there are also many natural-occurring objects mistaken as dinosaur eggs such as concretions or even fortuitously-shaped rocks. Despite these hurdles, dinosaur eggs remain one of the most desirable of all fossils. NOTE: Dinosaur egg and eggshells, by their nature as an ichnofossil, are challenging for private collectors to identify. None of the IDs I provide here are acceptable on a scientific level as I lack the tools to examine the cross section slices of my eggshells. However, for the sake of documentation I will still provide accurate names and locality here to the best of my ability. First up are my Oviraptorid eggs "Common" Name: Oviraptor egg Elongatoolithus sp. 71 - 66 mya | late Cretaceous Nanxiong Basin, Guangdong "Common" Name: Citipati egg Macroolithus yaotunensis 71 - 66 mya | late Cretaceous Nanxiong Basin, Guangdong Length: 8.78 inches (Note: Has composited eggshells) "Common" Name: Oviraptorid(small type) Nest Elongatoolithus sp. 71 - 66 mya | late Cretaceous Nanxiong Formation Guangdong

    Perinatal hadrosaurid tooth

    From the album: Aguja Formation

    A very small tooth from a "baby" hadrosaurid. It has feeding wear, so clearly not embryonic.
  7. Hello everyone, I have the opportunity to buy this set of 12 fossilised eggs. I shared several pictures. They seem perfectly real to me, but I would appreciate your expertise on authenticity! Thank you very much, Antonin [Seller verbiage removed]

    Edmontosaurus dental battery

    From the album: Hell Creek / Lance Formations

    A remarkable dental battery of the hadrosaurid dinosaur, Edmontosaurus annectens. Hadrosaurs had highly sophisticated teeth arranged in these batteries which advanced teeth in a conveyer-belt fashion to replace worn ones. Even the roots of teeth were used once the enameled crowns wore away. This one was in active use and fossilized when the animal died. This battery in particular is special, as it was collected by former forum member Troodon, seen in his "My Jurassic Park" thread here. It comes from a hadrosaur-dominated bone bed.
  9. Hey everyone I am preparing a rib from the Hell Creek formation it isn't in the greatest of shape and I still had a long way to go but wanted to start thinking about maybe trying restoration for the first time and wondering what you guys recommend. Here is the startand here is where I'm at right nowwith the right side there will need to be some fill to the missing bone. My question is though with the degree of curve on the right end do you think I'm close to the head and should try reconstructing the head? I could be looking at the curve wrong too and just have the bottom of the rib, either way though is there any method you guys use in reconstruction to get the bone texture? Thanks for the help I'll continue updating this as I get further into prepping it.

    Hadrosaur foot bone?

    Hello everyone. I was wondering if anyone can confirm or deny my ID on this fossil. My father in law found this in Montana when he was 16 along with associated bones. Some of the bones have dissolution features on the surface, but this phalanx is in decent shape. I identified it as a hadrosaur assuming Cretaceous age, but don't have much information on where it came from. The proximal end of the bone shows a clear darkened band where cartilage was once present, but rotted off. The notch on the proximal end of the bone makes me question my original identification. The bone is good sized and the proximal end shows a bumpy texture which indicates the epiphyseal plate may have detached, though it's hard to say for sure given the clear dissolution features on the surface of some of the other bones .I've also included a photo of the end of what I'm thinking is a limb bone if that helps.

    Hadrosaur spit tooth?

    Found what I believe is a hadrosaur spit tooth as soon as I opened my bag of Aguja Formation micro matrix! Can anyone confirm?

    Shed hadrosaurid teeth

    From the album: Hell Creek Formation Microsite

    Typical shed hadrosaurid (Edmontosaurus) teeth, a.k.a. "spitters." Most are river tumbled and missing their enamel. These teeth are quite common, as Edmontosaurus was abundant and regularly shed them from its arsenal of hundreds. A) teeth in occlusal view

    Edmontosaurus tooth discovery

    From the album: Hell Creek Formation Microsite

    A large hadrosaurid (Edmontosaurus annectens) dentary tooth, recovered from a channel deposit in Montana.
  14. I am confused is the dental battery only in the lower mandible or is it in the maxilla as well?
  15. Happy New Year everyone! Apparently I was good last year because I got gifted a blast cabinet and a mobile problast from vaniman which have been amazing. I made some mods to my hf cabinet that made it much more useful. I added a base frame and castors too it and changed the lighting to led bars which really improve the lighting. I also used some extra angle iron to the back to use as a mounting bracket for my magnifying lens. I also updated the switch to house some plugs. Here it is in all its glory. All in all I'm pretty happy with it the only thing I might do is cut the gloves out and use disposable gloves as the stock gloves are too large for my hand. Here is the air drying system that I put together I will definitely modify it in the future but it works great for now. For the first prep after a bit of practice I chose a fairly beat up Hadrosaur Chevron. It has a palm seed and a stick in the v that I though were pretty cool. There were definitely some mistakes but all in all I'm fairly happy with it. I'll probably go back and re-prep it later but for now I like it. Hope you enjoyed this and I can't wait to show you all the things I'll prep this year!

    Saurolophus Jaw

    Seller says this is a Saurolophus jaw. Is there anyway to identify? Is this legal to own as the species is form Mongolia?

    Chinese Dinosaur Eggshells

    Shown below are 3 different types of dinosaur eggshell, all said to be from the Gaugou Formation in China. The bottom left eggshell is labelled as coming from Dendroolithus, and I am confident in this identification. The other two types are supposed to come from Tarbosaurus bataar (top left) and Oviraptor philoceratops (right) however, and neither of these species are known from the Gaugou Formation, so the question is what they are actually from. Thanks in advance for any suggestions Othniel

    Hadrosaur Origins

    Howdy all, I've recently heard that hadrosaurs originated in Appalachia, and it was essentially their "ancestral homeland." Is this true?
  19. Came across with this cheap bargain hadrosaur egg, wondering if its actually a crushed egg or just rock and dirt concretion, the dealer gave me a video of it but im not sure if i can post it here so il just post the image.
  20. Fullux


    Howdy all, This is supposedly a hadrosaur tooth from the Woodbine formation of Dallas Texas that I'm very interested in. (If you know you know) Do y'all think the ID is accurate?
  21. The seller said it is a complete unhatched egg from China. 5.5 inches long. It looks weird to me. A fake or something else? Thanks
  22. So I was practicing looking for authentic Hadrosaur eggs after reading the how to spot a fake hadrosaur egg. Comparing it to real ones I’m thinking this is real. Am I correct in thinking this? If not I’d love to know what screams fake. What I see: Color seems right, pebbly texture on the shell, blemishes that don’t look painted, and cracks on the egg that are not shallow or drawn. Don’t look like the hollow fake ones that tend to hide most of the egg in matrix and look hatched or perfect.
  23. Hi all, I could not resist to get these 3 beautiful hadrosaur eggs. Those have been the last ones in my price range, and from a renowned local seller. Was wondering if anyone could give more insights. Here is what I have Possibly saurolophus 80 mio. year old, Cenomanian, Late Cretaceous Egg size 10.5 to 12cm (4 to 4.5"), about 8-9kg (18lbs) Xixia Basin, Henan province, China From an old collection Hoping no one tells me I bought some fakes .... (well, then I will return them ...). I am so curious. Getting them by tomorrow. Any comments from the experts here? Thanks a lot in advance. mr.rod

    Dinosaur egg??? Penarth Wales

    Hi there I found this and three others, one complete in penarth was wondering if it could be anything or just another coincidental rock formation. It does resemble the description and images of an egg, any input would be gratefully received thanks
