Unworn Hadrosaur tooth from the maxillary (upper jaw). Based on the size, it could be from a juvenile. -
I was taking a walk yesterday afternoon next to the Anacostia river in PG county (Maryland), and looked down to see this very interesting rock. Unfortunately I wasn't out looking for anything in particular, so I didn't bring a ruler to measure the tracks. I think these might be hadrosaur tracks to my very inexperienced eye? There have been other tracks discovered in this general area, notably the large assemblage of late Cretaceous tracks discovered outside NASA a few years ago, and hadrosaurs have been discovered from this general area/time period. Can anyone else confirm my suspicions?

Are these real? Hadrosaur and Oviraptor Eggs
DesertJerboa posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, Newbie here. Wondering if these items are real. The pair are billed as oviraptor eggs. The other is billed as a hadrosaur egg. Thanks very much for sharing your thoughts! Best, Z!.thumb.jpg.7554b3e340354392b967c53eff479b0d.jpg)

I found this fossil on top of the Unchompagre, in an area of the Morrison Formation. I am trying to verify if this is possibly a Dinosaur Fossil??

Hi TFF community, I recently purchased this small piece of Hadrosaur rib section originating from the Lance Creek Formation, Weston County, Wyoming. My question isn't to identify the Hadrosaur species (as its likely an Edmontosaurus sp. however if anyone can say with confidence then please do let me know!). My question is to ask if anyone can give more information or speculation towards what these curious scratch marks could be. The listing mentioned them possibly coming from a juvenile dromaeosaurid however I have my doubts based on the size of the markings but that's just my armature assumption. The markings show 3 scratches moving down the rib section, all of which are evenly spaces at 2.5mm away from each other and are in the classic theropod foot position. I've done some quick research towards the small flighted bird species that hail from the Lance Creek Formation but cant find much to match the size of these marks. I understand that these markings may also just be random damage that has been caused during the time this fragment has been buried, but opinion from others will be greatly appreciated. The fossil is 42mm x 24mm approx. I've also attached a microscopic look of the middle marking at 40x magnification if that helps. Thank you all for your time and help

A seller near me has a fossil egg. A hadrosaur egg of some sort. I think the seller is genuine, and I am fairly well committed to buying the egg at this stage, but want to confirm things before it all gets the final go ahead. I've looked at the various egg buying guides here, and though this doesn't look quite like the example eggs given it also doesn't look like any of the fake eggs. Can people please let me know if they think this is a genuine egg? Thanks for the help!

A couple larger dino vertebrae I found on the Judith River last year, I believe the larger round one is Hadrosaur but not certain, the longer rectangular shape vertebra I have no idea. I was hoping someone would be able to help identify.

Greetings, I have a bone fragment that's a mystery to me. This fragment is part of a find that I had posted in another thread in 2019 showing a Dental Battery. The dentary was presumed to be Edmontosaurus. The pictures here are of a 5" fragment that I would like to identify the bone & placement, this fragment also has a penetrating bite. The sediment that filled the bite area has been removed and the cavity seen in the pictures is from the bite. Two curved teeth about 4" or more penetrated completely through, pushing a lower tooth down into bone while two smaller teeth were sheared away. I've been unable to match this fragment with the other pieces I recovered and any assistance would be greatly appreciated. I found this on private land with permission. Rosebud County Montana.

Why are hadrosaur/triceratops tooth so hard to buy now
Raptor9468 posted a topic in Questions & Answers
Please do not leave online shop names in the comments, dm me if you want I have tried to find teeth of these two species for more than a year yet they never appear,used to see them online everywhere,is there something going on with the fossil quarries? -
From the album: Dinosaurs
Edmontosaurus annectens Hell Creek Fm., Harding Co., SD, USA Partial dental battery Hadrosaurs had the most histologically complex teeth of any animal, with six unique tissues. This allowed for differential wear, creating an ideal coarse surface for grinding plant matter. (Erickson et al. (2012)) -
An acquaintance asked me to post these pictures of what he believes is a hadrosaur jaw/head. Hadrosaur digits have been found in Minnesota. I do have to say that it is a very suggestive rock, enough so where I agreed to post it. :-) It was found in Mower county, SE Minnesota, among glacial drift near Austin, MN. For Scale I have to admit that it does look like teeth. :-) The bottom side of the "teeth". Bottom of rock. Side one. Side two. Thank you for your consideration. :-)

Hi all... I was sorting my finds from Big Brook, NJ, over the years and had a few whatzits. I'd much appreciate any insights you might be able to provide. The one in the middle looks similar (to me at least) to a hadrosaur tooth, but I don't like jumping to conclusions. The others... I couldn't even guess! Thanks for the look. (Scale in centimeters)

Associated Vertebrae?
Nanotyrannus35 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I'd came across an sale listed as an associated pair of juvenile Hadrosaur Dorsal vertebrae - from the Judith River Formation. I had been wondering, are they really associated, and how can you tell if fossils are associated? Here are the pictures from the seller. -

North Carolina Dinosaur or Mosasaur Vertebra or phalanges?
fossil_lover_2277 posted a topic in Fossil ID
Hi, I recently found a bone that looks like either a vertebra or a phalanges. The bone is from eastern North Carolina, legally collected from public land, and comes out of either the Cretaceous Tar Heel or Bladen formations. Both marine and freshwater organisms as well as dinosaurs are known to be found from the general area. The bone does not look like it comes from a turtle or crocodile, but I could be wrong. Is it a dinosaur or mosasaur bone, or something else? And no, there is no way this bone is Cenozoic. Thanks!

Found this while sifting a Cretaceous marine sight in upper New Jersey. Resembles a partial hadrosaur tooth but I'm not 100% on that ID and curious if it's actually something more common that I'm not aware of. It's approx. 1.9 cm (3/4") in length.

Are there any excursions other than Paleoprospectors where you pay for the fossil excursion and you can keep your finds? Hells Creek

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!

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

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?

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
