Troodon Posted September 30, 2016 Share Posted September 30, 2016 A lot of misidentified material from a single source: Description: Pachycephalosaurus Vertebra Fact: it's Thescelosaurus not Pachycephalosaurus Description: Theropod Vertebra Dinosaur Fact: Not dinosaurian probably Crocodile Description: Theropod Vertebra Dinosaur Fact: Not dinosaurian looks like a Champosaurus vert. Description: Theropod Finger Bone, Raptor, Dromaeosaur Fact: Not dinosaurian looks like turtle Description: Theropod Vertebra Dinosaur Fossil Fact: Not dinosaurian not sure may be Croc. or reptilian Description: Large Theropod Vertebra, Raptor Rex Fact: Don't believe it's Theropod or Raptor Rex looks more like a Thescelosaur 9 Link to comment Share on other sites More sharing options...

Ash Posted September 30, 2016 Share Posted September 30, 2016 Croc verts there are so different to the ones here. The ones here are sorta ball and socket type things.

Troodon Posted September 30, 2016 Author Share Posted September 30, 2016 I think most have the ball and socket. The first one shown is quite worn or incomplete because they are not very robust..has some characteristics of the one shown in photo. Definitely not dinosaurian Example from Hell Creek Formation 2 Link to comment Share on other sites More sharing options...
Ash Posted September 30, 2016 Share Posted September 30, 2016 Ah yep that shows it clearer, thanks.

Troodon Posted October 10, 2016 Author Share Posted October 10, 2016 Same seller has a new theropod toe bone for sale but the story is the same. Looks more like a Ornithischian than theropod. Possibly Thescelosaurus. Theropod toes bones from the Hell Creek typically have deep oval ligament pits and the ventral side is a bit more arched than flat. Better to run and catch dinner, yum yum 1 Link to comment Share on other sites More sharing options...

jpc Posted October 11, 2016 Share Posted October 11, 2016 Caudal croc verts starting maybe halfway down the tail do not have the ball and socket. They have flat edgs, but this one posted seems too short; they get rather long. Link to comment Share on other sites More sharing options...
Max-fossils Posted October 11, 2016 Share Posted October 11, 2016 Wow, thanks for the info! You seem to know a lot on the subject! So if I ever want to buy a dinosaur (or reptilian) fossil, I'll send a picture of it to you before to make sure I'm not seeing wrong info Thank you and warm regards, Max Max Derème "I feel an echo of the lightning each time I find a fossil.

Troodon Posted October 12, 2016 Author Share Posted October 12, 2016 If you are unsure of what youre buying it's always good practice to post it and get everyones in put in the forum. Just don't trust written descriptions. Link to comment Share on other sites More sharing options...
Troodon Posted October 16, 2016 Author Share Posted October 16, 2016 A beautiful trio of toe bones for sale from the Judith River Formation. The seller calls them Brachylophosaurus and I asked him how he come up with the ID. He said its the "most common" Wonder how he even came to that conclusion Just a reminder for all collectors, identifying isolated hadrosaur bones to a genus or species level is extremely difficult and only left to the most experienced paleontologist. ID: Hadrosaurid indet. Link to comment Share on other sites More sharing options...
LordTrilobite Posted October 16, 2016 Share Posted October 16, 2016 Omg that sure is lovely... I think I'll keep an eye on this one. As far as I know Brachylophosaurus is by far the most common Hadrosaur in Judith River Formation. But it being common is still not a really good reason to label it as such. I agree, Hadrosauridae indet. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Troodon Posted October 16, 2016 Author Share Posted October 16, 2016 This is Judith in Montana and I'm not sure there has been enough discoveries, unlike Alberta, to call anything common. Could be wrong. It's a great looking group. Link to comment Share on other sites More sharing options...
LordTrilobite Posted October 18, 2016 Share Posted October 18, 2016 Well I grabbed that last Hadrosaur toe item. Now to wait for it to arrive! I'll likely be labeling it as Hadrosaurid indet, instead of Brachylophosaurus. But I'll definitely try to find out more about the identity.

Troodon Posted October 18, 2016 Author Share Posted October 18, 2016 Great, nice pickup the preservation is super. It's in good hands to provide an opportunity to ID them Link to comment Share on other sites More sharing options...
LordTrilobite Posted October 29, 2016 Share Posted October 29, 2016 I got that Hadrosaurid toe today. The three bones are definitely really nicely preserved. For the time being I'll be labeling it as Hadrosauridae indet. Though hopefully I can find out some more info on it. Some quick research showed that it's a correct composition of the three phalanges of the fourth toe. I also found out it's from the left foot (which goes nice with the other left toe bone I already had from Judith River MT). So that's the good. There's not a lot of downside to this piece. It probably shouldn't have been labeled as Brachylophosaurus on the auction as it's more than possible that it's from different types of Hadrosaurs. Otherwise the first two bones don't fit perfectly. But that's to be expected from a composite. All in all, I'm happy. Another thing I noticed. I used Edmontosaurus foot images for reference. While definitely phalanges from toe 4. There is some notable differences in morphology in these bones compared to Edmontosaurus. now to find good reference of the Judith River Hadrosaurs...

Troodon Posted October 29, 2016 Author Share Posted October 29, 2016 Nice looking bones, nice pickup. JR references are going to be difficult, good luck. If I see any will pass them on. Link to comment Share on other sites More sharing options...
Troodon Posted October 29, 2016 Author Share Posted October 29, 2016 @LordTrilobite have you seen this Hadrosaur out of the Judith to complicate your identification http://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0141304 2 Link to comment Share on other sites More sharing options...
LordTrilobite Posted October 29, 2016 Share Posted October 29, 2016 I have heard of the dinosaur before. I was not aware it was present in Judith River MT. Thanks. It's a shame the paper doesn't include any foot material. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Troodon Posted October 30, 2016 Author Share Posted October 30, 2016 I'm guessing but there are probably few articulated hadrosaur specimens in the Judith of MT. Most papers I see come from material in Alberta. Link to comment Share on other sites More sharing options...
LordTrilobite Posted October 30, 2016 Share Posted October 30, 2016 Well... One of the best preserved dinosaurs ever found is from Judith River MT. Leonardo the Brachylophosaurus. And as far as I know other "mummies" have been found from the same location as well. Articulated material is definitely there. The trick is finding good photos.
