  1. This past weekend some good buddies and I headed down to a river in SE NC which is known for producing cretaceous fossils in a lag deposit among other things. The group consisted of folks from NC, VA, MD and PA. Weather forecast Saturday for central/eastern VA and NE NC was really BAD, but forecast was great for where we were headed, mid-80s, mostly sunny with a nice breeze. Even more exciting and important to us (especially at this time of year), the river level was low enough for us to access the lag deposit material. In the field with us for the first time were a few of Ray's @aerogrower "magic cubes." They came in the mail about an hour before I headed south with the boat and I was hoping they would bring us all good luck. Obviously, they did that and more! I just wish Don @sixgill pete could have joined us. Maybe next time. Most of us met Friday night at the hotel, had a great dinner at a local steak & seafood place across the street and then hung out chatting and catching up about life since our last fossil hunting trip together. Two of our group were still gun shy of the hotel from their encounter with "bed bugs" during our December trip, so they drove in early Saturday morning to meet us. Saturday morning started out with perfect weather and eight (8) very excited fossil hunters. Getting the boat in at the ramp was interesting to say the least, given its shad season and the fishermen were everywhere on the ramp, dock, etc. They didn't like having to stop or move even for just a few minutes so we could launch. Water temp was in the low 70s and we headed out to our intended location. When we got there, we perused the area, discussed and debated what was the best strategy and where to start. 2 others started a spot to the right of the boat and I started a spot to the left of the boat. My very 1st screen produced a bunch of sharks teeth and 2 deinosuchus vertebrae, 1 with very fresh shovel marks, if you know what I mean. I will try and post photos of the shark teeth & vert, coprolites, misc. croc teeth and other stuff this evening. One of our group moved farther to the left and started exploring and surface collecting. Dang if he didn't come walking back up with a nice deinosuchus tooth and other stuff, right off the beach. Here's a photo of some of @Daleksec and his dad's croc/deinosuchus teeth. They have quite a few more. Note one of Ray's "cubes" getting its inaugural photo op. Eventually, the guys to the right of the boat gave up and helped explore my area. They are nice folks and good friends, so I only minded a little. :-) j/k So, wouldn't you know that it would have to be one of my buddies who pulled this beauty of a Hadrosaur vert out. This particular friend is known by all to have a lucky golden horseshoe in a certain place. While all this was going on, @Daleksec had walked farther down to the left where his dad was exploring and found this vertebrae exposed in situ. Note, Ray's @aerogrower "magic cube" making another appearance in this photo. As you can tell, the vert came out in several pieces despite our best efforts. Daleksec will put it back together as best as possible and we'll post more photos of it. During the course of Saturday, one of our friends found 2 nice Theropod teeth with one being about an inch and one being about 1/4 inch. Both were serrated. I will add photos once they are cleaned up. Besides the multitude of croc and shark teeth and the 2 deinosuchus verts I found early on, one of my prizes from Saturday was this gorgeous, but yet suggestively shaped object. :-) The laughter and stories going around about my coprolite find are not fit for printing on a family oriented website. We finally finished up hunting/collecting about 415pm Saturday with most of us filthy and sore but VERY happy as we headed back to the boat ramp. Saturday evening was another night of hanging out, chatting and a great dinner with good friends. Though, we did go to bed much earlier than Friday night and Ibuprofen was definitely on the menu. Sunday morning we woke to drizzle, low-50s and breezy. It was going to be a cold/wet ride in the boat back to our spot. Not to mention, at least one thunderstorm had come through in the early hours of the morning. Forecast looked OK though with a little drizzle but most of the rain holding off till after 1pm. We got back to our spot and started at it again. Quite a few more deinosuchus teeth/verts were found along with many more sharks teeth and other assorted goodies. Given the awesome and spectacular finds everyone else had on Saturday, I rubbed my newly acquired "magic cube" for some personal good luck. About an hour into the hunting, the magic cube came through for me. While working through the matrix I heard this distinct "chunk" sound of metal hitting on something very solid. I should have snapped a photo right then but there was no way I was vacating the spot so one of my friends could jump in given the heads turning around at the "chunk" sound. I probed a little more and pulled this beautiful hunk of bone out. This is the very first Hadrosaur vertebrae I've ever found. I've been present when several others were found (by the friend with the golden horseshoe), and he even found a very nice dino toe bone in front of me. But this one is mine. After all the excitement and joking about my "happy" dance died down we went back to the task at hand. And, of course it didn't take long for the golden horseshoe to show up AGAIN!!! He pulled this Hadrosaur tail vertebrae out about a foot from where I had found mine. The cube was working it's magic. About 1230p it started sprinkling and was threatening to turn into a steady rain. We packed up and headed back to the ramp. Photos of all 3 Hadrosaur verts in the next post.
  2. Many of us collect Edmontosaurus sp. skull elements and bones. Attached find a very interesting paper that describes skull elements on an Edmontosaurus regalis which is the Hadrosaur species found in the early Maastrichtian of Alberta. It's a very close cousin to the late Maastrichtian Edmontosaurus annectens found in the Hell Creek/Lance Formations. Beautiful Maxilla Paper: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0175253
  3. 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.

  5. 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
  6. 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
  7. 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!
  8. Edmontosaurus annectens Vertebra

    Caudal vertebra of an Edmontosaurus annectens. This is a vertebra from somewhere near the end of the tail.
  9. 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!
  10. 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.
  11. 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.

  14. 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!
  15. 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!
  16. 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.
  17. 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
  18. 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!
  19. 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.
