  1. My Edmontosaurus collection

    Gday all, this is my Edmontosaurus collection so far. Most of the bones here are from the left foot of an Edmontosaurus but there are a few other pieces, rib sections and teeth. I'm trying to build a complete left foot, originally I didn't set out to do this but I bought a few toe bones and soon realised that the majority of them were from the left foot so I decided to turn it into a project. It will take me some time to source the correct bones but that will also give me some time to save for them! I have a few bones that aren't right, for example met 111-1 is the correct bone but just too small so I need a larger one to keep everything in proportion but waiting and searching is all part of the fun. Thanks for looking, Dave.

  3. Hadrosaur Tooth

    Hi guys I recently got sent a package from some friends for my birthday which included some nice little goodies including tickets to see the Dinosaurs of china event in Nottingham this summer, Included was this lovely piece identified as purely teeth and bone from a Hadrosaur which was found in the Lance Formation, I was just trying to get any information regarding a species level is possible? I'm not entirely sure if this is possible but hopefully you guys familiar with the lance formation fauna may help. Many thanks, Chris.H
  4. Hello, I picked up some Hadrosaur skin on auction last week and not having much experience in skin I'm hoping someone can comment on its authenticity? Thank you
  5. Me and my brother (shajzer64) went to the Trenton State Museum today for identification on some fossils we found in Monmouth County over the past few months. We also brought along a few fossils we found through the past few years that I believed could be Hadrosaur teeth. We met with Mr. Paris and had a great day. The highlight was a large Mosasaur brain case my brother found last month but we were also very happy to find out that the potential Hadrosaur teeth we had were all indeed Hadrosaur teeth; we had struggled with this ID in the pat so it was nice to know we turned the corner with that one. The last highlight was two crocodile teeth which are also Cretaceous. It was a great start to the morning and definitely strong motivation to hit the streams again as soon as possible!
  6. Edmontosaurus annectens Vertebra

    Caudal vertebra of an Edmontosaurus annectens. This is a vertebra from somewhere near the end of the tail.
  7. Dinosaur skin are a highly sought-after fossil. The ones usually available to collectors are Edmontosaurus skin impressions from Lance, or Hell Creek Formation, and they aren't as rare or expensive as you might expect, fetching up to 100-200 USD per inch depending on quality. However, it is easy to mistake a bumpy piece of rock, mud sediment, septarian nodule, concretions, or a coral fossil as dino skin. Right now there are at least several of such on our favorite auction site. Here are examples of fossils/pseudofossils mistaken as dinosaur skin: And here are real Edmontosaurus skin impressions: Positives: Negatives: So how do we tell real skin impressions from misidentified ones? Honestly, it isn't always easy, but here are four basic guidelines. 1) Skin impressions come as negatives or positives. If it comes with both, even better! 2) Skin impressions are rarely ever a complete piece by themselves(not the way a tooth or an ammonite is). Instead, skin impressions are often fragments, or look like they are broken off from larger chunks 3) There should be a uniform shape to each individual scale/osteoderm. Refer to the negative pictures above 4) Most skin impressions come from South Dakota. If you get another locality, be on extra alert - it's either another species(and thus very expensive), or misidentified If in doubt, ask the forum before purchasing. There are plenty of experts here glad to help. Have fun shopping!
  8. Hadrosaur toe

    Hadrosauridae indet. A slender Digit IV phalanx 1 of a left Hadrosaurid foot. Several different hadrosaurs are present at Judith River Formation. There are Hadrosaurs from both Lambeosaurinae and Saurolophinae present in Judith River Formation. These include Brachylophosaurus, Probrachylophosaurus, Lambeosaurus and Corythosaurus.
  9. My growing collection

    Here's a couple of pics of my growing collection. It is a mixture of purchased pieces and self collected pieces, it's all a bit disorganised at the moment but I will work out a way of displaying it properly. I really like the hadrosaur pieces, I would like to get to the point where I could put together a complete foot, although it will be mixed and matched I still think it would display well. Thanks for looking.

  12. Hi everyone, I have this nice Hadrosaur mummified skin, bought online. Just wondering what genus/species this could be? Edmontosaurus perhaps? It was found in the Hell Creek Formation in Montana, 65 mya. Any suggestions will be much appreciated! Cheers!
  13. Hi there, I bought a hadrosaur caudal vertebra online a while ago and I was wondering what genus/species it is? It is from Southeastern Utah - I'm not sure which formation, the seller didn't say. Just joined up and would appreciate any help or suggestions! Thank you!
  14. Hadrosauridae Tooth

    Indet. Hadrosauridae, self collected from a river site. Dinosaur teeth from North Carolina are very uncommon and very understudied. Remains other than teeth are mostly unidentifiable bone shards.
  15. How Hadrosaur Teeth Work

    Attached find a PLOS blog on the workings of a Hadrosaur Dental Batteries. It's a bit technical but gives you a better view of a pretty complex operation of over 300 teeth in a jaw. http://blogs.plos.org/paleocomm/2016/09/14/all-the-better-to-chew-you-with-my-dear/ Here is the paper article.pdf
  16. Hi everyone. I've come across this hadrosaur egg on a well known fossil/gem dealer's site. It's described as from the "Xixia Basin, in the Henan province of China", which research tells me has an embargo on hadrosaur eggs. It's a very well known gem/fossil site selling it, and states "This fossil specimen will come with a certificate of authenticity." (Authenticated by who exactly? Sure...) Naturally these pictures are as good as the resolution gets, and the price point (over $1k USD) seems pretty high risk for a possible fake. I've stayed away from eggs in the past since they're so rampantly faked, but eventually want one (from any dino, really) for my collection. Thoughts? Thanks!
  17. My Dino Dig Trip

    It's September and a great time to go out in the badlands of Montana and South Dakota hunting for Dinosaurs. I try to go out at least twice a year unfortunately family health issues prevented me from a earlier trip so I was happy to be able to go on this one. My South Dakota site is in the upper Hell Creek Formation and full of the hadrosaur Edmontosaurus annectens plus the occasional theropod tooth. All of the bones collected come from this site however some of the teeth I show come from a channel deposit in Montana. I've been collecting this site for 20 years and its still delivering. We are on the edge of a bluff and the fossil layer can be between 2 to 4 feet. Lots of good bones are to be found but we also have lots of punky or junk bones and about 70 % is collectible. The site is quite large and like I said last year we have no idea of its size but it contains scores of hadrosaurs all disarticulated. No skulls are found but all the elements that make up a skull are collected. Some pictures of the site and locality The collecting area is between the white lines My tools are pretty simple and those shown are used 90% of the time. I also use a pick. We have no equipment to remove the overburden so its our biggest challenge and can be quite daunting for those not physically in shape, like most of us The collecting layer starts off with a crumbly pebble deposit where the teeth are found then turns into sand where little is found and most of the bones are in the lower hard clay deposit. Most of the bones fracture when exposed to air so glue may be necessary to keep them together during extraction. I use two Paleobond products : PB4417 which is a field consolidant and comes off easily during prep but does not have structural strength. PB002 is used when I need strength on larger bones. I also carry a debonder just in case I glue my fingers together or as in this trip a fellow collector glued his glove to his hand. Glue can be dangerous since it cures quickly. Its more a safety issue but sometimes needed on bones/teeth in the field. I found this product "Golden West Super Solvent" used in the prep lab of the Royal Tyrrell Museum. Its effective has acetone but had no odor or effects on the skin and is not flammable or volatile. Its more costly than acetone but for the amount I use it works and no smell. In addition to showing everyone what I found I would also like to share the process of extracting some of the bones. Very few get to collect in this formation so it might be interesting to see the process and how hard it is to get from the Dirt to the Finished product.

  24. I'm extremely excited to announce that two days ago at 3:30 a newly discovered dinosaur vertebra was recovered from a Late Cretaceous Campanian formation in West Tennessee. This is only the 4th. dinosaurian vertebra to ever be found in Tennessee! It's also the first dinosaur vertebra I've ever found in my life. The specimen is from the tail section on the vertebrae column of a Hadrosaur. The neural canal and neural arch are still plainly visible. Specimen is missing the neural spine and also possible Chevron bone. This is a historic achievement for paleontology in Tennessee and here is the first look. As I'm sure by now, everyone on the Forum knows, my cell takes terrible pics, I hope to prep the specimen soon and show better shots of it. These photos were taken the day it was recovered and I have no others presently available. I will post more pics on this thread when the specimen is cleaned.
