First hadrosaur vertebrae, got it for a very good price. Maybe too good. Thoughts?
thefloralplesiosaur posted a topic in Fossil ID
Hi everyone! Got this at an auction for a really good price (probably because of the missing portion) labeled as hadrosaur. 66-67 million years old. from hell creek formation in South Dakota. length about 3.3 inches, width roughly the same. I guess it seems a bit too good to be true for me as it’s my first vertebrae specimen and it’s also a hadrosaur which I see commonly running for +. Thanks in advance!

Real Hadrosaur Egg?
TeethCollector posted a topic in Is It Real? How to Recognize Fossil Fabrications
I received an offer for a Hadrosaur egg from Nanxiong formation.. and I am confused because the egg looks too perfect... and the crack of the egg looks unnatural to me. Would you share your opinions?

I am told this is an fossiles egg from dendroolitihus sp. It should be real, but who knows?

Finished my latest prep. Now, I realize that in the worlds of both commercial and academic paleo, this is a useless, junk fossil. Its an unassociated, partial in poor condition, and any final monetary value doesnt meet the time invested in the prep. However, its special for me in that its my first "wild" find. I hiked, explored, tracked the float, found the end of this in the face of a wall, then excavated it. I was hoping for a much more complete fossil, but this was it. It is highly fractured and deeply root rotted. But I carefully disassembled all its parts, cleaned them, consolidated them, reassembled into proper positions and finally repaired the gaps to strengthen it. Now, I've dug and prepped lots of fossils over the last 12 years, but all have come from sites someone else found. They did the leg work and established the quarry, I just dug in it. Nobody knew this was there until I found it. Im still hopeful theres more of the animal scattered behind it. An Ed. vert centrum washed out from a few feet away. Hopefully I'll get the chance to check the site again. Just a side comment... I hate prepping this type of fossil. I glued and consolidated this as I uncovered it, which also glues all the matrix in place. That helps prevent the fossil from collapsing into gravel en route home, but then I have to dissolve the glue and completely disassemble all the broken chunks, then pray I can put everything back where it belongs. anatomy and taphonomy. Every fossil tells a story and the following is my attempt at reading that tale. I found a great PDF article https://archives.palarch.nl/inde.../jvp/article/view/447/439 specifically about the pes of hadrosaurines. It would appear my fossil is the distal end of Metatarsal III, likely left side. The erosional break was at the point where MT-II and MT-IV were located, and the bone was pointing distally into the matrix, so no other metatarsal bones would have been remaining if deposited in articulation. Phalanges III was not found on excavation, although it is possible to still be in situ and just more separated than the distance I examined. However, the likely reality is that this indicates a disarticulated and isolated element. The measurement on the width is 160mm which would make it an adult, although not at the largest size. The fossil has a high degree of fracturing which is likely due to a combination of freeze/thaw cycles and plant root invasion. Beyond this, the fossil still has a mostly intact surface which says that it did not suffer long term surface weathering or osteophageous beetle predation. The in-situ damage was confined to the highest points, which shows it possibly suffered peri-depositional damage. The matrix was a loosely consolidated mudstone without associated gravels or stone inclusions, indicating a low energy environment such as a delta, marsh, or low flow river. Walter Stein believes the layer to be a continuation of a densely fossiliferous, multi-taxic bone bed discovered about 1/4 mile away. The fossil as I started prepping. After clearing off the matrix. distal end proximal end prepped and repaired

My wife and I recently traveled to Fairbanks, Alaska for a mini vacation and toured the Museum of the North on the University of Alaska, Fairbanks campus. It brought back some old memories as I completed my undergraduate training there in 1986. Here are a few pictures from the displays that I found interesting. The hadrosaurs display is fairly new and in the entryway Mammoth display Dinosaur interpretive displaysRay Troll art. Enjoy! AK Hiker

Genuine Hadrosaur egg?
JohnBurrows posted a topic in Is It Real? How to Recognize Fossil Fabrications
This is supposed to be a Hadrosaur egg from China, from an older collection. I'd appreciate any input. From the images I've seen its not obvious, but more convincing than some fakes I've seen. I'm afraid other than 'Hadrosaur' and 'China' I don't have any further information..thumb.jpg.fa38be47a6e9b77578138d60034547ce.jpg)

Hadrosaur egg -- Chinese
FF7_Yuffie posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, Any thoughts on this? It is a Hadrosaur egg from Guangdong, China. 9.4cm x 8.8 x 6. I know it's far from the best egg you'll see--but I was offered it for a good price, less than even I've seen poor conditioned eggs go for) . But does anyone see any restoration/composite to it? Now, I wish to check--the grey is eggshell, still partially covered by matrix? Or is the grey bits, which I am thinking is ill-cleaned eggshell, actually not eggshell either? I'm considering it for a piece for my desk at work here in Taipei--got my eye on a better possible egg to ship to my collection in England. Thanks for the help

Hi there I’m new to this site ..... could this possibly be a Hadrosaur Egg? I found it down a long coastal track on the Wild Coast in Transkei South Africa. It’s extremely heavy! Many thanks in advance . Cheers. Kevin.

Hello, I am waiting to here back from the seller a more specific location, so I will update when I get a county/town. But info I have thus far is this is a Hadrosaur column, tail vertebra, supposedly from the Two Medicine Formation of Montana. Is the description of it being Hadrosaur correct? I assume if Hadrosaur, it will be difficult to narrow down further given the number of different Hadrosaur species there are.It is 6 fused vertebra, and if it's Hadrosaur, it might make a nice display piece for me so I will likely go for it. I've also requested some extra photos. The 2nd vert is also sold as Hadrosaur, from Two Medicine too. But it doesn't look like any Hadrosaur vert I've seen, with the really concave front centrum and the back part of the centrum bulging out. I've also requested extra info that I will update with if/when the seller messages me. Does anyone have a clue what it is, if not Hadrosaur? Many thanks as always---hoping to bulk out my collection with some more interesting, larger pieces. If I win the broken trike horn and if this vert column checks out, they would be a nice pair to add along with the raptor vert I am also gonna pick up soon.

Hello, Can someone take a look at this and give your thoughts? I bought it without getting it ID'd because of it's ridiculously low price--if I waited to get it ID'd it would have probably been snapped up. So, figured it was worth a buy now, id later. Anyway, it is sold as been "dinosaur vertebra" from Hell Creek, Montana. I think it is Edmontosaurus because of the heart-shaped centrum--others online seem to have that shape to them. I was wondering if it might also be a Thescelosaurus vertebra given the small size, but most of them I see seem to have more rounded centrums, whereas this is quite prominently heartshaped. Apologies for the poor seller's photos, I'll get some better ones if needed once it arrives. But if someone can give it an ID now, I can update my fossil record database and that would be great. Many thanks

From the album: Aguja Formation
Dinosaur material is uncommon in this matrix. This is a fragment of a small hadrosaur tooth. -
Went on a wild fossil hunting trip today out on private land in the Dinosaur Park fm. and found something that I’ve since reported to the Tyrrell. My best guess is a partial hadrosaur tail. The specimen is about 3 feet long by 1.5 feet wide. There was no other associated material nearby but there may be more of this dinosaur under the surface. I’ll also post a few of my favourite surface finds for today. I have a before and after photo of a vert, a large partial rib and some tyrannosaur teeth & a croc tooth.

I'll start with the jrf vertebrae which I believe to be a hadrosaur cervical wondering if it is possible to narrow it down to a species if possible? And again anyone who is taking the time to look over these I thank you very much in advance.

...so I headed out to find some Dinos. All fossils dinosaur park fm. Got some new land permissions so I have lots of area to wander. Here’s some notable finds from today. Large hadrosaur (or possibly ceratopsian) foot bone, large hadrosaur foot claw, tyrannosaurid caudal vert, possible tyrannosaurid toe bone, and some indet. fused verts. These will be pictured, there were various other verts and smaller bones found that I may post later.

Hi! I got this Hadrosaur caudal vert from the two medicine formation. in Pondera County. I was wondering what part of the tail this bone would have come from? the seller says it is likely a proximal vertebra, but couldn't give any details on its placement. Is there any possible way you can tell what part of the tail this fossil belonged to? assuming a grown individual of the species. If exact placement isn't possible, Ill settle for general region. The centrum of the Vert is 2.7 x 2.3. x 2.2" and the process is 7.6" long in a straightline including the anterior points of articulation. As always I can provide more detailed pictures/measurements of requested parts of the specimen.

Hello, I received this yesterday as a birthday gift - it was sold as an imprint of hadrosaur skin, Cretaceous, from Hell Creek. Do you think it really is hadrosaur skin?

Hello people, I am new user of this forum from Madrid (Spain)

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.

I purchased these two fossils a while ago. Both are from the Hell Creek Formation in South Dakota, and both were described as hadrosaur jaws. They definitely seem to resemble the jaws of hadrosaurs, however I've noticed that the empty tooth rows of ceratopsians look extremely similar (to my untrained eyes), which is making me reconsider the seller's ID. I am hoping that someone out there with more knowledge can state confidently if these are ceratopsian or hadrosaur, and preferably if they can briefly explain why they think so. Bonus points if you can state if these are from the upper or lower jaws, or confidently state the genus. (From my limited research, it seems Edmontosaurus is the only hadrosaur described for the Hell Creek in South Dakota; the most abundant ceratopsian is Triceratops, but Torosaurus is also possible, as is Tatankaceratops, and of course the always popular "not yet described".) Let me know if additional photos would help your ID.

These are two Hadrosaurus jaw fragments I’ve had for awhile. As far as I know they are from the Hell Creek formation of Montana. I think they might be Edmontosaurus but I really can’t tell. The fragment exhibiting tooth channels is about 8 inches in length. The other fragment or chunk exhibits many broken teeth and is about 4 inches in length. @Troodon @jpc might like to have a look?

Hello, I am hoping someone can help identify this fossilized vertebrae that was found along the Missouri River near St. Louis, MO. It is 2" across.

Hello all. A decade ago, before I started keeping proper track of the specimens I own, I purchased a partial femur specimen (for context, it was fairly cheap, less than $150 I think). Anyway, I 'think' that it was from a Hadrosaur, but I don't think the seller knew for sure -- and I know for sure that I don't know for sure! Anyway, I don't recall the formation (I'm going to guess Judith River, but that's based on very little). Any, if anyone is able to readily identify/confirm that the partial femur is from a hadrosaur, or from something else, I'd deeply appreciate it. The specimen is highly mineralized and heavy; please see photos. Thanks!

Hello! I see this jaw with teeth from Ouled Abdoun Basin (Morocco). I read about the new Ajnabia descovered this year. What do you think? Real dinosaur or only a fish? Thank you so much.

Hadrosaur trackway contribution
dinosaur man posted a topic in Partners in Paleontology - Member Contributions to Science
I have recently been looking at some of my photos from trips and found photos of when I was in Alberta in 2018. I saw a photo of a Hadrosaur footprint from a trackway in Dinosaur Provincial Park that me and my brother found. I also read not to long ago that no big trackways have been found in this area so I decided to give the information and location to the Palaeontologist at the Royal Tyrrell Museum in Drumheller, Alberta. I was responded by Dr. Caleb Brown, he told me that I was most likely right and it was probably Hadrosaur. I am currently waiting for him to reply again to see what he thinks about the other information of the trackway and footprint that I gave him. One of the footprints outlined in the photo with pen.
